Breeding Field Spaniels

Complete Guide for Responsible Breeders

Breeding Field Spaniels presents unique challenges not found in more popular sporting breeds. With fewer than 200 puppies registered annually in the United States and a small global gene pool, Field Spaniel breeders must balance breed type preservation with genetic health management while navigating the practical challenges of limited stud availability. This comprehensive guide addresses the specific concerns of maintaining this rare breed while producing healthy, functional hunting companions.

Breed Overview

The Field Spaniel was developed in England during the mid-to-late 1800s from crosses between English Cocker Spaniels, Sussex Spaniels, and other spaniel varieties. Initially bred as an all-black show dog, early breeding for exaggerated features nearly destroyed the breed. The first Field Spaniel registered with the AKC was Coleshill Rufus in 1894, but the breed disappeared from American registries between 1916 and the late 1960s when dedicated breeders undertook breed revival efforts.

The modern Field Spaniel, revived through careful preservation breeding in the 1960s, is a functional hunting companion built for endurance in heavy cover and water. Unlike the more popular English Springer Spaniel, the Field Spaniel is slightly longer in body with moderate bone and a noble, docile temperament. The breed ranks 160th in AKC popularity with stable but limited registration numbers, reflecting its status as a rare breed maintained by a small community of dedicated preservation breeders.

The Field Spaniel Society of America (FSSA) serves as the AKC parent club, providing extensive breeder education resources and health research initiatives specific to the breed's small population.

Breed Standard Summary for Breeders

The Field Spaniel standard emphasizes balance, moderation, and functional hunting ability. Breeders must focus on maintaining the breed's distinct identity while avoiding the extremes that plagued early development.

Size specifications:

Males: 17-19 inches at the withers, 40-55 pounds

Females: 16-18 inches at the withers, 35-50 pounds

Critical structural priorities:

Balance and moderate proportions with a length-to-height ratio of approximately 7:6 (slightly longer than tall)

Sound, effortless movement with drive from the rear and reach from the front

Noble head with long, lean muzzle (avoid short, cocker-type heads)

Moderate bone and substance appropriate for all-day field work (neither light nor coarse)

Level or slightly sloping topline from withers to croup

Functional coat with silky texture and adequate feathering that provides water resistance

Disqualifications:

Sable pattern (lighter undercoat with darker shading or tipping, with or without mask)

Serious faults affecting breeding stock selection:

• Cobbiness or undue length (loss of the moderate 7:6 ratio)
• Lack of balance or substance
• Light bone insufficient for field work
• Tail carried above the back (indicates improper temperament or structure)
• Lack of feathering (indicates poor coat genetics)
• Excessive timidity or aggression (temperament unsoundness)

Breeders should prioritize balance, movement soundness, and stable temperament above color preferences, as the small gene pool makes it critical to select breeding stock on overall quality rather than single traits.

Reproductive Profile

Field Spaniels typically have moderate-sized litters appropriate for their body size. Average litter size is 5-6 puppies, with a typical range of 4-8 puppies. This is smaller than the average litter size for English Springer Spaniels (6-8 puppies) but consistent with other moderate-sized spaniels like the American Water Spaniel.

The C-section rate is approximately 12%, which is relatively low compared to brachycephalic breeds. Most Field Spaniels whelp naturally without intervention, though first-time dams may require assistance and close monitoring.

Breed-specific fertility considerations:

Small gene pool due to breed rarity (under 200 puppies born annually in the USA) creates genetic bottlenecks

Limited stud availability requires shipped semen or extensive travel, making fresh and frozen AI common

Some lines show reduced fertility, requiring careful monitoring of progesterone levels and optimal breeding timing

Higher coefficient of inbreeding across the breed population requires careful outcross planning

Geographic spread of breeders means natural breeding is often impractical

AI suitability: Fresh and frozen AI are commonly used in Field Spaniels due to limited stud availability and the geographic spread of breeders. Natural breeding is preferred when logistically possible, but the majority of litters are produced using artificial insemination. Breeders should establish relationships with reproductive veterinarians experienced with AI protocols.

Breeding Age and Timeline

Field Spaniels typically experience their first heat cycle at 6-10 months of age, though this varies by individual and bloodline. However, physical and mental maturity occur later than first heat.

Recommended first breeding age:

Females: 24 months minimum (after all health clearances are obtained)

Males: 18-24 months (after all health clearances are obtained)

OFA testing minimum age: 24 months for hip dysplasia evaluation, which is a CHIC requirement and determines the earliest possible age for first breeding.

Breeding career parameters:

Maximum recommended litters per female: 5 litters

Recommended retirement age: 6-8 years

Minimum interval between litters: 12-18 months to allow full recovery

Complete breeding timeline:

1. 6-10 months: First heat cycle (record date, monitor cycle length)
2. 18 months: Begin temperament and conformation evaluation
3. 24 months: Complete all CHIC health testing (hip dysplasia, eye examination, thyroid panel)
4. 24+ months: Eligible for first breeding if all clearances are excellent/good
5. Progesterone testing begins at first signs of proestrus (typically 5-7 days before ovulation)
6. Breeding occurs 2-4 days after progesterone rise indicates ovulation
7. Pregnancy confirmation via ultrasound at 28-30 days
8. Radiographs at day 55+ to determine litter size and assess puppy positioning
9. Whelping at day 63 +/- 3 days
10. Puppies go home at 8-10 weeks after health checks, vaccinations, and microchipping

In rare breeds, breeders must also consider the availability of suitable mates when planning breeding timelines. Finding an appropriate outcross with complementary pedigree and health clearances may require waiting longer than initially planned.

Required Health Testing

The Canine Health Information Center (CHIC) requires three specific health tests for Field Spaniels. All breeding stock should obtain CHIC certification before being bred.

CHIC-required tests:

Hip Dysplasia (OFA or PennHIP) - $250 one-time

• Screens for hip joint malformation and degenerative joint disease
• X-rays submitted to OFA for evaluation at 24 months minimum
• Results rated Excellent, Good, Fair, Borderline, Mild, Moderate, or Severe
• Only breed dogs with Excellent, Good, or Fair ratings

Eye Examination (CAER) - $75 annual

• Screens for Progressive Retinal Atrophy, cataracts, retinal dysplasia, and other hereditary eye diseases
• Performed by board-certified veterinary ophthalmologist
• Annual examination required; must be current within 12 months
• Critical given PRA and cataract prevalence in the breed

Autoimmune Thyroiditis (OFA Thyroid Panel) - $150 one-time

• Screens for hypothyroidism and autoimmune thyroiditis
• Blood draw sent to OFA-approved laboratory
• Includes T4, Free T4, T3, Free T3, T4AA, T3AA, and TgAA

Total estimated CHIC cost per breeding dog: $475 initial plus $75 annually for eye examinations

OFA application and processing fees: Add approximately $100-150 for radiograph submissions and database registration.

Additional recommended tests (not CHIC-required):

Cardiac Evaluation (OFA): $100 - Screens for congenital heart defects and cardiomyopathy

Elbow Dysplasia (OFA): $100 - Screens for elbow joint malformation

DNA Profile (AKC): $50 - Identity verification for parentage confirmation, particularly important when using AI

In rare breeds, maintaining comprehensive health records and transparency about test results is critical for collective breed health improvement. The Field Spaniel community strongly encourages submitting all test results to OFA databases, regardless of outcome, to provide accurate prevalence data.

Hereditary Health Conditions

Field Spaniels have several hereditary health concerns that breeders must screen for and manage through selective breeding decisions. The small gene pool makes health testing and transparency particularly important.

Idiopathic Epilepsy (Late-Onset Seizures)

Prevalence: Moderate (the most prominent health concern in the breed)

Inheritance mode: Suspected polygenic (complex inheritance not yet fully understood)

DNA test available: No

Clinical signs: Seizures typically beginning after age 6 years, often with no identifiable cause. Seizures may be focal or generalized, varying in frequency and severity. This late-onset form is particularly challenging for breeders because affected dogs may already have been bred before symptoms appear.

Age of onset: 6+ years (late-onset form)

Breeding implications: The late-onset nature and suspected complex inheritance make this condition difficult to eliminate. Breeders should track seizure incidence in pedigrees and avoid breeding dogs with multiple affected relatives. Research is ongoing to identify genetic markers.

Hip Dysplasia

Prevalence: Moderate (18% prevalence based on OFA data)

Inheritance mode: Polygenic with environmental factors

DNA test available: No

Clinical signs: Abnormal hip joint development leading to arthritis, difficulty rising, reluctance to jump or climb stairs, bunny-hopping gait, decreased range of motion. Signs may appear from 6 months to 2 years, though some dogs remain asymptomatic until middle age.

Age of onset: 6 months to 2 years (signs may not appear until middle age)

Breeding implications: Only breed dogs with OFA ratings of Excellent, Good, or Fair. Consider the hip ratings of parents, grandparents, and siblings when evaluating breeding stock.

Autoimmune Thyroiditis/Hypothyroidism

Prevalence: Moderate (15% prevalence in the breed)

Inheritance mode: Polygenic with breed predisposition

DNA test available: No

Clinical signs: Weight gain, lethargy, cold intolerance, poor coat quality, skin infections, reproductive issues including irregular heat cycles and reduced fertility.

Age of onset: 2-6 years

Breeding implications: OFA thyroid panel is a CHIC requirement. Do not breed dogs with abnormal thyroid values or positive thyroid antibodies (T4AA, T3AA, or TgAA).

Progressive Retinal Atrophy (PRA)

Prevalence: Low to moderate

Inheritance mode: Autosomal recessive (most common form)

DNA test available: Yes (for specific PRA forms)

Clinical signs: Night blindness progressing to complete blindness, dilated pupils, increased eye shine.

Age of onset: 3-9 years (varies by PRA type)

Breeding implications: DNA testing allows identification of carriers. Do not breed two carriers together. Carriers can be bred to clear dogs to preserve genetic diversity.

Hereditary Cataracts

Prevalence: Low to moderate (10% prevalence)

Inheritance mode: Varies by cataract type (autosomal recessive or dominant)

DNA test available: No for most forms

Clinical signs: Opacity of the lens, impaired vision, eventual blindness if severe.

Age of onset: 1-5 years (juvenile form) or 6+ years (adult-onset)

Breeding implications: Annual CAER eye examinations catch cataracts before breeding. Do not breed dogs with hereditary cataracts.

Cardiac Conditions

Prevalence: Low (5% prevalence)

Inheritance mode: Varies by specific condition

DNA test available: No

Clinical signs: Heart murmurs, exercise intolerance, coughing, difficulty breathing, lethargy.

Age of onset: Variable (congenital defects present at birth, acquired conditions develop later)

Breeding implications: Cardiac evaluation is recommended though not CHIC-required. Monitor for heart murmurs during routine veterinary exams.

Color and Coat Genetics

Field Spaniels are bred in solid colors and roans with moderate genetic complexity. Understanding color genetics is important for predicting litter outcomes and avoiding disqualifying patterns.

AKC-accepted colors:

• Black (self-colored)
• Liver (self-colored)
• Golden liver (self-colored)
• Black with tan points
• Liver with tan points
• Black roan (bi-colored with white ticking)
• Liver roan (bi-colored with white ticking)
• Golden liver roan (bi-colored with white ticking)
• Any of the above with white markings on throat, chest, and/or brisket (small markings acceptable)

Disqualifying colors:

Sable pattern (lighter undercoat with darker overlay or tipping, with or without mask)

Relevant genetic loci:

B locus (liver/chocolate): B/B or B/b produces black pigment; b/b produces liver pigment

E locus (extension): Controls distribution of pigment; E/- allows full pigment expression

A locus (agouti/tan points): at/at produces tan point pattern; dominant alleles produce self-colored dogs

K locus (dominant black): Dominant K allele produces solid black regardless of A locus; ky/ky allows expression of A locus patterns

S locus (white spotting): Controls white markings; moderate expression creates roaning pattern

T locus (ticking/roan): Creates the roan pattern where white areas are interspersed with colored hairs

Breeding for color:

Black x Black: All black (unless both carry recessive liver)

Liver x Liver: All liver

Black x Liver: All black if black parent is B/B; 50% black, 50% liver if black parent is B/b

Tan points: Require two copies of the recessive at allele; breeding two tan point dogs produces all tan point puppies

Health-linked color concerns: There are no known health issues directly linked to any accepted Field Spaniel color. The sable pattern is disqualified primarily to maintain breed type distinction from other spaniel breeds.

Complexity tier: Medium - Most Field Spaniel breeders can predict color outcomes with basic understanding of B locus (liver), A locus (tan points), and S/T loci (roan patterns). DNA color testing is available but rarely necessary.

Selecting Breeding Stock

Selecting breeding stock in a rare breed requires balancing conformation quality, health clearances, temperament, and genetic diversity. Field Spaniel breeders face the additional challenge of limited stud availability and the need to maintain breed type while managing coefficients of inbreeding.

Conformation priorities from the standard:

• Balance and moderate proportions (avoid extremes in any direction; length-to-height ratio of approximately 7:6)
• Sound movement with effortless, ground-covering stride showing drive and reach
• Correct topline (level or slightly sloping from withers to croup)
• Noble head type with adequate muzzle length (avoid short, cocker-like heads)
• Good bone and substance without coarseness (moderate for all-day field work)
• Proper coat texture with adequate feathering that provides water resistance

Common faults to select against:

• Short, cobby body or excessive length (loss of moderate proportions)
• Light bone and lack of substance (insufficient for field work)
• Short muzzle or heavy head (cocker-type head is incorrect)
• Poor rear angulation and weak drive
• Straight shoulders limiting reach
• Soft, fluffy coat lacking water-repellent quality
• Tail carriage above the back (incorrect temperament or structure)
• Timid or overly aggressive temperament

Temperament evaluation: Field Spaniels should be docile, sensitive, and fun-loving with a great affinity for human companionship. Evaluate puppies and breeding stock for stable, willing temperament with moderate activity level. Avoid excessive shyness or reactivity, as these traits are contrary to the breed's purpose as a companion hunting dog. Breeders should test for hunting instinct in working lines, though not all Field Spaniels are actively hunted today.

Coefficient of Inbreeding (COI) management:

Average breed COI: 15% (relatively high due to breed rarity)

Target COI for individual litters: Under 6.25% (equivalent to avoiding first-cousin or closer matings)

In rare breeds, some degree of inbreeding is unavoidable, but breeders should strive to produce the lowest COI possible while maintaining type and health. Use pedigree database tools to calculate COI before confirming breedings. Outcrosses to less-related lines are valuable even if they require compromises on minor conformation points.

Stud selection criteria:

• Complete CHIC health clearances with excellent/good ratings
• Proven temperament and conformation quality
• Complementary pedigree with low COI when crossed with your bitch
• Proven fertility and breeding history if available
• Geographic accessibility or frozen semen availability

Stud fee range: $800-$1,500 depending on the stud's show record, health clearances, and demand. Many Field Spaniel breeders offer stud service at the lower end of this range to encourage genetic diversity. Pick-of-litter arrangements are common in rare breeds as an alternative to cash stud fees.

Whelping and Neonatal Care

Field Spaniels generally whelp naturally without complications, though the small gene pool creates some risk factors that require careful monitoring.

Recommended whelping method: Natural whelping is the norm for Field Spaniels. Most dams whelp easily, though first-time dams may need encouragement and assistance. Have your veterinarian's emergency contact information readily available.

Breed-specific complications:

• Small gene pool may increase the risk of genetic complications, though this is not breed-defining
• First-time dams may need assistance with puppy positioning or membrane removal
• Occasional dystocia due to puppy size or positioning (but less common than in brachycephalic breeds)
• Monitor closely for fading puppy syndrome, which can occur in breeds with genetic bottlenecks

Average birth weight:

Male puppies: 9-11 ounces

Female puppies: 8-10 ounces

Daily weight gain target: Puppies should gain 5-10% of birth weight per day. Healthy puppies should double their birth weight within 7-10 days. Weigh puppies daily for the first two weeks to catch weight loss early.

Whelping box setup: Provide a whelping box at least 4 feet x 4 feet with pig rails to prevent crushing. Maintain ambient temperature of 80-85°F for the first week, gradually decreasing to 75°F by week four.

Fading puppy protocol: If a puppy fails to gain weight or shows signs of weakness, consult your veterinarian immediately. Supplement with puppy formula and increase feeding frequency. Some genetic conditions cannot be overcome, but early intervention saves puppies in many cases.

Tail docking, dewclaw removal, and ear cropping: Field Spaniels are shown in their natural state. Dewclaws are not removed, tails are not docked, and ear cropping is not practiced in the breed.

Puppy Development Milestones

Field Spaniel puppies develop steadily from birth through adolescence. Understanding normal growth patterns helps breeders evaluate puppies and advise owners.

Birth to 2 weeks (neonatal period):

Puppies are born with eyes and ears closed, relying entirely on dam. Focus on warmth, nursing, and weight gain. Eyes begin to open around 10-14 days.

2 to 4 weeks (transitional period):

Eyes and ears fully open. Begin to walk and interact with littermates. Start transitioning to solid food around 3-4 weeks.

3 to 14 weeks (critical socialization window):

Primary socialization period when puppies learn social cues and adapt to new experiences. Introduce to varied environments, surfaces, sounds, people, and other animals. Puppy temperament testing can begin around 7-8 weeks.

5 to 6 weeks: Weaning begins as puppies transition fully to solid food. Dam begins to naturally reduce nursing sessions.

8 to 10 weeks: Standard go-home age. Puppies should have received first vaccinations, been dewormed, and received microchips. Breeders often conduct final evaluations for show prospect placement at 8 weeks.

8 weeks, 6 months, and 12 months: Key structural evaluation ages. Breeders retaining show prospects should re-evaluate at 6 months and again at 12 months as growth plates close and adult structure emerges.

12 to 14 months: Field Spaniels reach adult size. Height is typically complete by 12 months, though males may continue to fill out and develop substance through 18-24 months.

Socialization window emphasis: Continue socialization efforts through 6 months to build confident, stable adults. Field Spaniels are sensitive dogs and benefit from gradual, positive exposure to varied experiences.

Breeding Economics

Breeding Field Spaniels as a rare breed presents unique economic realities. Limited demand means lower puppy prices than more popular breeds, while health testing and breeding costs remain constant regardless of breed popularity.

Cost breakdown for a typical litter (natural whelping, 6 puppies):

Pre-breeding costs (per breeding female):

Health testing (CHIC requirements): $650

Show or hunt test entry fees (optional but recommended): $500-2,000

Per-litter costs:

Stud fee: $1,000 (average for Field Spaniels)

Progesterone testing: $300 (4-6 tests to pinpoint ovulation)

Prenatal veterinary care: $450 (ultrasound, radiographs, prenatal checkups)

Whelping costs (natural): $300 (supplies, bedding, heating)

Whelping costs (emergency C-section if needed): $2,000-3,000

Puppy veterinary care: $125 per puppy x 6 = $750 (first vaccinations, deworming, health check)

Food and supplies: $400 (dam's increased food needs plus puppy food for 8 weeks)

AKC registration: $200 (litter registration plus individual puppy registrations)

Total cost for natural whelping: $4,050

Total cost if C-section required: $6,050+

Revenue:

Average puppy price:

Pet quality: $3,000

Show quality: $3,500

Average litter revenue (6 puppies at $3,000 each): $18,000

Net per litter (natural whelping): $18,000 - $4,050 = $13,950 gross profit

However, this does not account for:

• Failed breedings requiring repeat stud fees and progesterone testing
• Smaller litters (4 puppies reduces revenue to $12,000)
• Puppies retained for show/breeding evaluation (reduces revenue)
• Travel costs to shows, stud dog locations, or veterinary specialists
• Ongoing costs of maintaining breeding dogs (food, routine vet care, training)
• Time investment (hundreds of hours per litter in puppy care, socialization, correspondence with puppy buyers)

Reality for rare breed breeders: Most Field Spaniel breeders are preservation breeders who prioritize breed quality over profit. The small market means puppies may take longer to place, and breeders may retain multiple puppies to evaluate for breeding programs. The financial return rarely compensates for time invested, particularly when a breeder shows dogs to championship titles or competes in field trials.

Breeding Field Spaniels is a labor of love supporting a rare breed, not a profitable business venture.

Frequently Asked Questions

How many puppies do Field Spaniels typically have?

Field Spaniels average 5-6 puppies per litter, with a typical range of 4-8 puppies. Litter size is influenced by dam age (first-time mothers may have smaller litters), breeding timing (optimal progesterone timing increases litter size), and individual genetics. The breed's moderate size correlates with moderate litter size compared to larger sporting breeds like English Springer Spaniels.

Do Field Spaniels need C-sections?

No, Field Spaniels have a relatively low C-section rate of approximately 12%. Most dams whelp naturally without intervention. However, first-time dams may need assistance, and breeders should monitor labor progression carefully. Emergency C-sections are occasionally needed for dystocia caused by puppy positioning or uterine inertia, but this is not a breed-defining characteristic. Have your veterinarian's emergency contact information available during whelping.

What health tests are required for breeding Field Spaniels?

The CHIC program requires three health tests: Hip Dysplasia evaluation (OFA or PennHIP), annual Eye Examination (CAER), and Autoimmune Thyroiditis screening (OFA Thyroid Panel). Total cost is approximately $650 for initial testing plus $75 annually for eye exams. Additional recommended tests include cardiac evaluation, elbow dysplasia screening, and DNA profiling. All breeding dogs should obtain CHIC certification before being bred.

How much does it cost to breed Field Spaniels?

Total costs for a Field Spaniel litter average $4,050 for natural whelping or $6,050+ if a C-section is required. Major expenses include health testing ($650), stud fee ($1,000), progesterone testing ($300), prenatal care ($450), whelping supplies ($300), puppy veterinary care ($750 for 6 puppies), food ($400), and registrations ($200). Puppies typically sell for $3,000-$3,500, generating gross revenue of $18,000 for a 6-puppy litter.

At what age can you breed a Field Spaniel?

Females should be at least 24 months old before their first breeding, after obtaining all health clearances including OFA hip evaluation at 24 months minimum. Males can be bred at 18-24 months after health clearances. Breeding younger than 24 months prevents completion of required OFA hip testing and does not allow full physical maturity. Field Spaniels can be bred until 6-8 years of age, with a recommended maximum of 5 litters per female.

How much do Field Spaniel puppies cost?

Field Spaniel puppies typically cost $3,000 for pet quality and $3,500 for show-quality puppies. The relatively modest pricing compared to more popular breeds reflects limited market demand for this rare breed. Puppies from health-tested parents with show championships or field titles may command prices at the higher end of the range. Co-owned puppies or puppies sold on breeding terms may have different pricing structures.

What are the most common health problems in Field Spaniels?

The most significant health concerns in Field Spaniels are idiopathic epilepsy (late-onset seizures, typically after age 6), hip dysplasia (18% prevalence), autoimmune thyroiditis (15% prevalence), Progressive Retinal Atrophy (low to moderate prevalence), and hereditary cataracts (10% prevalence). Annual eye examinations and comprehensive health testing help breeders make informed breeding decisions to reduce disease prevalence. The breed's small population makes health transparency critical.

Is breeding Field Spaniels profitable?

Breeding Field Spaniels is rarely profitable when accounting for time investment, facility costs, and potential complications. While a 6-puppy litter generates approximately $13,950 gross profit after direct expenses, this does not include failed breedings, retained show prospects, travel costs, ongoing dog maintenance, or the hundreds of hours invested in puppy care and socialization. Most Field Spaniel breeders are preservation breeders focused on maintaining this rare breed rather than generating income.

How rare are Field Spaniels?

Field Spaniels are quite rare, with fewer than 200 puppies registered annually in the United States and a small global population. The breed ranks 160th in AKC popularity. This rarity creates unique breeding challenges including limited stud availability, higher coefficients of inbreeding, and the need for extensive coordination among breeders to maintain genetic diversity. New Field Spaniel breeders should connect with the Field Spaniel Society of America for mentorship and breeding guidance.

What is the coefficient of inbreeding for Field Spaniels?

The average coefficient of inbreeding (COI) for Field Spaniels is approximately 15% at the breed level, which is relatively high due to the small population and historical genetic bottlenecks during breed revival. Responsible breeders should aim for individual litter COIs under 6.25% (equivalent to avoiding first-cousin or closer matings) to maximize genetic diversity. Using pedigree database tools to calculate COI before breeding is essential for rare breed preservation.

Can Field Spaniels be bred naturally or is AI necessary?

Natural breeding is preferred when logistically possible, but fresh and frozen AI are commonly used in Field Spaniels due to limited stud availability and the geographic spread of breeders. Many breedings involve shipped chilled or frozen semen, requiring veterinary assistance with AI and precise progesterone timing. Breeders should establish relationships with reproductive veterinarians experienced with AI protocols. Despite the prevalence of AI, Field Spaniels have good fertility when proper timing protocols are followed.

What makes Field Spaniels different from English Springer Spaniels or Cocker Spaniels?

Field Spaniels are longer in body and more moderate in build than Cocker Spaniels, with a distinct noble head type and a specific 7:6 length-to-height ratio. Compared to English Springer Spaniels, Field Spaniels are slightly longer, slightly lower to the ground, and have a different head shape with a longer, leaner muzzle. Temperamentally, Field Spaniels are known for being particularly docile and sensitive, making them excellent companion dogs as well as functional hunters. The breed's rarity and distinct type make preserving these differences essential to maintaining the breed.
