Breeding Chinooks

Complete Guide for Responsible Breeders

Breeding Chinooks requires exceptional dedication to preserving one of America's rarest native dog breeds. With fewer than 1,000 dogs worldwide and a documented bottleneck of just 11 breeding animals in 1981, every Chinook breeding decision carries conservation significance alongside the standard responsibilities of health testing, temperament evaluation, and puppy placement.

Breed Overview

The Chinook was developed in the early 1900s by Arthur Treadwell Walden in Wonalancet, New Hampshire, at the foot of the White Mountains. Named after Walden's lead sled dog, the breed was created to combine the power of freighting breeds with the speed of lighter racing sled dogs. The Chinook's development combined working Husky-type dogs with Mastiff-type breeds and possibly Belgian Shepherds, creating a uniquely American sled dog optimized for hauling freight in polar expeditions while maintaining competitive speed.

By 1981, the breed faced near-extinction with only 28 Chinooks remaining worldwide, with just 11 suitable for breeding. Through dedicated conservation efforts led by breed enthusiasts and the Chinook Club of America, the population has slowly recovered. The Chinook achieved full AKC recognition in 2013 and holds the distinction of being the official state dog of New Hampshire.

Currently ranking 180th in AKC popularity, the Chinook remains a rare breed with stable registration trends. Unlike the more popular Siberian Husky or Alaskan Malamute, which number in the thousands of annual registrations, Chinook breeders are participating in active conservation breeding with careful attention to genetic diversity and population health.

The parent breed club, the Chinook Club of America (https://www.chinookclubofamerica.org/), provides extensive breeder education, maintains the breed's health database, and coordinates conservation efforts.

Breed Standard Summary for Breeders

The Chinook is an athletic, hard-bodied dog showing excellent forward reach and rear extension in a seemingly tireless gait. The breed is slightly longer than tall, with moderate bone and a lean, muscular appearance rather than the heavy substance seen in freighting-only breeds. Males range from 24-27 inches and 65-75 pounds, while females measure 22-25 inches and 50-60 pounds. Clear sexual dimorphism in size and substance is expected and necessary for breed type.

The head is broad and wedge-shaped with an intelligent, inquisitive, and kind expression. Eye color is strictly brown (any other color is a disqualification), and the breed's hallmark tawny coloration with dark ear and muzzle shading is essential to type.

Key structural priorities for breeding stock:

• Correct proportion: slightly longer than tall (not square, not excessively long)
• Moderate bone with lean, hard musculature (avoid both refined and overly heavy builds)
• Excellent gait mechanics with strong forward reach and rear extension
• Sound hips and elbows for working ability
• Proper coat texture: medium-length double coat, neither excessively short, long, rough, nor shaggy

Disqualifications that eliminate dogs from breeding programs:

• Any eye color other than brown (blue, amber, or parti-colored eyes)
• Any coat color other than tawny as described in the standard

Serious faults to select against:

• Trimming of coat or whiskers (indicates poor natural coat quality)
• White markings beyond acceptable patterns (blazes, socks, scarves)
• Lack of sexual dimorphism (undersized males or oversized, masculine females)
• Poor movement or structural unsoundness

The Chinook matures slowly, reaching full physical development at 4-5 years of age. Structural evaluation should account for this extended maturation timeline, and breeding decisions should not be rushed based on appearance at 12-18 months.

Reproductive Profile

Chinooks average 6 puppies per litter, with a typical range of 3-9 puppies. The breed's litter size distribution follows a normal curve with most litters falling between 5-7 puppies.

The C-section rate is approximately 20%, which is higher than the 10-15% rate for similar-sized working breeds like the Samoyed but substantially lower than brachycephalic breeds. Natural whelping is the norm, but breeders should be prepared for surgical intervention, particularly in cases of uterine inertia (which affects 5.36% of Chinook females) or hydrops fetalis (fluid accumulation in the fetus).

Fertility challenges specific to Chinooks:

• Small breeding population severely limits outcrossing options and increases inbreeding coefficients
• Cryptorchidism in males occurs at an unusually high rate of 14.63% (any cryptorchid male should be neutered and excluded from breeding)
• Occasional uterine inertia requiring oxytocin or surgical intervention
• Stillbirth rate of 3.8% (approximately 1 puppy per 4 litters)

Natural breeding is preferred when feasible, but fresh and frozen AI are commonly used for breedings requiring geographic distance or to maximize genetic diversity by accessing stud dogs from across the country. Given the small population size, AI has been instrumental in conservation efforts by allowing breeders to outcross to dogs they cannot travel to for natural breeding.

Breeding Age and Timeline

Chinook females typically experience their first heat at 10-12 months of age, though some may be earlier or later. The recommended first breeding age is 24 months minimum for females, after OFA hip certification has been completed. Males can be bred as early as 18-24 months, preferably after preliminary OFA hip evaluation.

The OFA minimum testing age for hips is 24 months. Many Chinook breeders prefer to wait until 30 months for final hip certification to allow for full skeletal maturity, given the breed's slow maturation.

Breeding timeline:

• 18-24 months: Complete all DNA testing (MDR1, Chondrodysplasia)
• 24 months: OFA hip radiographs and CAER eye examination
• 24-30 months: First breeding (females) if health testing is complete and temperament evaluation confirms suitability
• Annual: CAER eye examination before each breeding
• Maximum litters per female: 5 litters
• Retirement age: 7-8 years

Given the conservation status of the breed, breeders should work closely with the Chinook Club of America's breeding committee to coordinate pedigrees and maximize genetic diversity. The average coefficient of inbreeding (COI) in the breed is approximately 15%, and breeders should aim for breedings with COI under 10% when possible.

Required Health Testing

The Chinook has four mandatory health tests for CHIC certification. All breeding stock should complete these tests before the first breeding and maintain annual eye examinations.

CHIC Required Tests:

• Hip Dysplasia (OFA or PennHIP): Screens for abnormal formation of the hip socket causing arthritis and lameness. Cost: $250. One-time radiograph at 24+ months.
• Eye Examination (OFA CAER): Screens for hereditary ocular diseases including cataracts, progressive retinal atrophy, and other abnormalities. Cost: $75. Required annually before each breeding.
• MDR1 Genetic Test: Screens for multidrug sensitivity mutation causing adverse reactions to common medications including ivermectin, loperamide, and certain chemotherapy drugs. Cost: $75. One-time DNA test.
• Chondrodysplasia Genetic Test: Screens for skeletal development disorder causing disproportionate dwarfism. Cost: $75. One-time DNA test.

Total estimated health testing cost per breeding dog: $475 (initial year; $75 annually thereafter for eye exams)

Tests are submitted to the Orthopedic Foundation for Animals (OFA). DNA tests (MDR1 and Chondrodysplasia) can be performed through the OFA's partner laboratories or directly through Washington State University's Veterinary Genetics Laboratory.

Additional recommended tests:

• Cardiac Evaluation (OFA): Screens for congenital and acquired heart conditions. Cost: $150.
• Thyroid Panel (OFA): Screens for autoimmune thyroiditis and hypothyroidism. Cost: $125.
• Epilepsy/Dyskinesia DNA Panel: Research-based screening for genetic markers associated with seizure disorders. Cost: $100. (Note: This is an evolving area of research; no definitive test is currently available, but ongoing studies may identify markers.)

Hereditary Health Conditions

Chinooks face several hereditary health conditions that breeders must understand and screen for. The breed's genetic bottleneck in the 1980s concentrated some issues, though dedicated breeding practices have improved population health.

Cryptorchidism (14.63% prevalence in males): Cryptorchidism, the failure of one or both testicles to descend into the scrotum, is the most prevalent hereditary condition in Chinooks. The inheritance pattern is polygenic with sex-limited expression. Clinical signs include one or both testicles remaining in the abdomen or inguinal canal beyond 6-8 months of age. Retained testicles carry significantly increased cancer risk and require surgical removal. Any cryptorchid male should be neutered and excluded from breeding. Females from cryptorchid-producing pedigrees should be evaluated carefully before inclusion in breeding programs.

Seizure Disorders - Epilepsy and Dyskinesia (8.37% prevalence): Chinooks experience two distinct neurological conditions: classical epilepsy presenting as grand mal seizures with loss of consciousness, and dyskinesia presenting as movement disorders or partial seizures. The inheritance mode is not fully understood but a genetic component is strongly suspected. Age of onset is typically 1-5 years. No definitive DNA test exists, but ongoing research at multiple universities aims to identify genetic markers. Dogs with seizure disorders should not be bred, and close relatives should be evaluated carefully.

Hip Dysplasia (7.11% prevalence): Hip dysplasia in Chinooks is lower than many large working breeds but still significant enough to warrant mandatory OFA screening. The condition is polygenic (multiple genes contribute) with no DNA test available. Clinical signs include lameness, difficulty rising, bunny-hopping gait, reluctance to jump or climb stairs, and rear leg muscle atrophy. Symptoms may appear from 6 months to 2 years, but full radiographic evaluation requires skeletal maturity at 24+ months. Only dogs with OFA ratings of Good or Excellent should be bred; Fair may be acceptable in rare cases with exceptional genetic diversity value and when bred to Excellent hips.

Hot Spots / Allergic Dermatitis (8.37% prevalence): Acute moist dermatitis ("hot spots") occurs in Chinooks with seasonal or environmental allergies. The condition is multifactorial with genetic predisposition plus environmental triggers. Clinical signs include hair loss, red inflamed skin, intense itching, licking, and secondary bacterial infection. While not life-threatening, dogs with severe or recurring allergic dermatitis should be evaluated for breeding suitability, as the condition impacts quality of life.

MDR1 Mutation (Variable prevalence): The MDR1 (multidrug resistance) mutation is inherited as autosomal recessive (homozygous mutant/mutant dogs are fully affected) or partial sensitivity (heterozygous normal/mutant carriers). Dogs with two copies of the mutation experience neurotoxicity following administration of ivermectin, loperamide, and certain chemotherapy drugs, with symptoms including tremors, disorientation, blindness, and potentially coma or death. A DNA test is available and mandatory for CHIC. Breeding two carriers together is discouraged due to the 25% risk of homozygous affected puppies. Clear dogs can be safely bred to carriers; all puppies should be DNA tested before drug administration.

Chondrodysplasia / CDPA (Low prevalence): Chondrodysplasia is an autosomal recessive skeletal disorder causing disproportionate dwarfism with shortened limbs. Unlike breeds where this trait is a defining characteristic (Dachshund, Basset Hound), it is undesirable in Chinooks. A DNA test identifies carriers. Breeding two carriers together results in 25% affected puppies. Carriers can be bred to clear dogs safely, and some breeders include carriers in programs to preserve other valuable genetic traits, provided the mate is tested clear.

Color and Coat Genetics

The Chinook has one of the most restricted color palettes in the working group. The breed standard requires tawny coloration ranging from honey to deep reddish-gold, with darker shading on the ears and muzzle being highly desirable. Any coat color other than tawny is a disqualification.

Accepted colors:

• Tawny (ranging from honey to deep reddish-gold) with dark ear and muzzle shading
• Dilute tawny (lighter tawny with diluted pigmentation from dd genotype)
• Symmetrical white or cream to pale gold markings on cheeks, throat, chest, breeches, and underside

Disqualifying colors:

• Any solid color other than tawny
• Black and tan (though genetically possible from recessive alleles)
• Recessive black
• White markings beyond accepted patterns (blazes, socks, scarves)

Relevant genetic loci:

• A locus (Agouti): Ay (tawny/sable) is the dominant accepted allele. All breed-standard Chinooks carry at least one Ay allele. The breed may carry recessive a (recessive black) or at (black and tan) alleles hidden beneath Ay, but these are not expressed and are considered undesirable.
• E locus (Extension): Em (melanistic mask, producing the desirable dark muzzle), E (wild-type), and e (recessive red) are all present in the breed. The Em allele creates the preferred dark facial shading.
• D locus (Dilution): D (intense pigment) or d (dilute). Dogs with dd genotype produce dilute tawny coloration (lighter, washed-out appearance). Dilution is acceptable in the standard but less desirable than fully pigmented tawny.
• B locus (Brown): All tested Chinooks to date are BB (black pigment). Brown (liver) pigment has not been documented and may be fixed out of the breed.
• S locus (White spotting): Controls the extent of white markings. Minimal to moderate white (Irish spotting pattern) is acceptable; excessive white is a serious fault.

Health-linked color considerations: Dilute tawny (dd genotype) is not associated with color dilution alopecia in Chinooks, unlike some breeds where dilution causes coat and skin problems. However, breeders generally prefer breeding for full pigmentation (DD or Dd) when possible to maintain the rich tawny color that is a hallmark of breed type.

Breeding color predictions:

• Tawny x Tawny (both Ay/Ay or Ay/at or Ay/a): All puppies will be tawny
• Dogs with dd genotype (dilute) x DD (intense): All puppies will be Dd (intense tawny, but carrying dilute)
• Two Dd carriers x Dd carriers: 25% dd (dilute tawny), 75% D_ (intense tawny)

Because the Chinook gene pool is limited, color genetics are less complex than in breeds with multiple accepted colors. The primary selection criteria should be maintaining the desired dark ear and muzzle shading (selecting for Em allele) and avoiding dilute pigmentation when possible.

Selecting Breeding Stock

Selecting breeding stock in a rare breed requires balancing conformation quality, health testing results, temperament, and genetic diversity. In Chinooks, pedigree diversity may occasionally outweigh minor structural faults, provided the dog meets minimum health and temperament standards.

Conformation priorities:

• Correct tawny coloration with desirable dark shading on ears and muzzle (Em allele)
• Sound movement with excellent reach and drive; the Chinook is a working sled dog and must move efficiently
• Proper proportion: slightly longer than tall (not square like a Malamute, not overly long)
• Moderate bone with lean, hard musculature (neither refined nor excessively heavy)
• Wedge-shaped head with kind, intelligent expression
• Dark brown eyes (any other color is a disqualification and genetic defect)

Common faults to select against:

• Lack of dark ear and muzzle shading (dog appears washed out or pale)
• Excessive or undesirable white markings (white blazes, socks, scarves)
• Trimmed coat or whiskers (indicates poor natural coat quality requiring artificial enhancement)
• Poor gait mechanics (restricted reach, lack of drive, pacing, or inefficient movement)
• Over- or under-sized for sex (males under 24 inches or over 27 inches; females under 22 inches or over 25 inches)
• Lack of sexual dimorphism (masculine females or refined males)

Temperament evaluation: The Chinook Club of America emphasizes dignified, calm, trainable temperament with a strong bond to family. Chinooks should be friendly without being overly exuberant, and capable of working independently without constant handler direction. Shyness, which historically affected 7.95% of the breed, is undesirable and dogs showing fearful or anxious temperament should not be bred.

Evaluate breeding prospects for confident socialization, sound sensitivity tolerance (important for working environments), and suitability for multi-dog households (as sled dogs are kenneled in groups). Aggression toward other dogs or people is atypical and disqualifies a dog from breeding consideration.

Genetic diversity considerations: The average coefficient of inbreeding (COI) in Chinooks is approximately 15%, which is elevated compared to breeds with larger populations. Breeders should target breedings with COI under 10% when possible. The Chinook Club of America maintains a breed database and provides pedigree analysis tools to help breeders make informed decisions.

When selecting a stud dog, prioritize genetic diversity and complementary traits. A less-finished show dog from an underrepresented bloodline may contribute more to breed health than a champion from a commonly used line. Work with the breed club's breeding committee for pedigree analysis.

Stud fee range: $500-$1,500, with fees varying based on the dog's health testing, show record, and pedigree value. Given the conservation priority, some breeders negotiate reduced or waived stud fees for breedings that maximize genetic diversity.

Whelping and Neonatal Care

Chinooks typically whelp naturally, but breeders must be prepared for complications given the 20% C-section rate. This rate is higher than the 10-15% average for similar-sized working breeds, likely due to the genetic bottleneck and small population size.

Breed-specific whelping complications:

• C-section rate of 20%: Higher than similar-sized breeds. Factors include uterine inertia, dystocia from large puppies, and hydrops fetalis.
• Uterine inertia (5.36% of females): Primary uterine inertia (failure to initiate labor) or secondary inertia (labor begins but stops). May respond to oxytocin or require surgical delivery.
• Hydrops fetalis: Fluid accumulation in one or more fetuses, causing dystocia and requiring surgical intervention.
• Stillbirth rate of 3.8%: Approximately 1 puppy per 4 litters. Monitor for weak or non-viable puppies at birth.

Whelping preparation: Establish a relationship with a reproductive veterinarian experienced with medium-large breeds. Have funds available for emergency C-section ($1,800 average cost). Monitor progesterone levels starting at day 57-58 to predict whelping date accurately and detect delays.

Birth weights and neonatal targets:

• Male puppies: 14-16 oz at birth
• Female puppies: 12-14 oz at birth
• Daily weight gain target: 5-10% of body weight daily in first two weeks
• Puppies should double their birth weight by day 7-10

Puppies failing to gain weight or losing weight require supplemental feeding and veterinary evaluation. Weigh all puppies twice daily for the first week, then daily through week 3.

Neonatal care: Chinooks do not require dewclaw removal, tail docking, or ear cropping. The breed is shown in natural condition. Any cosmetic alterations are serious faults.

Monitor for:

• Fading puppy syndrome (hypothermia, hypoglycemia, dehydration, failure to nurse)
• Aspiration pneumonia from bottle-feeding
• Cleft palate (check all puppies at birth by visual inspection and palpation of hard palate)
• Cryptorchidism in males (testicles should be descended by 8 weeks; if not palpable by 6 months, dog is cryptorchid)

Puppy Development Milestones

Chinook puppies grow steadily from birth through 8 weeks, with males averaging slightly heavier than females throughout.

Growth chart: At birth, males average 14-16 oz and females 12-14 oz. By 8 weeks, males reach approximately 17 lbs and females approximately 15 lbs. Puppies should gain 5-10% of their body weight daily during the first two weeks.

Weekly milestones:

• Week 0-2 (Neonatal period): Eyes and ears closed. Puppies sleep 90% of the time and nurse. Thermoregulation is immature; maintain whelping box temperature at 85-90°F for week 1, gradually reducing to 80°F by week 3.
• Week 2-3: Eyes open around day 10-14. Ears open around day 14-18. Puppies begin to stand and take wobbly steps.
• Week 3-4: Teeth emerge. Puppies begin to play with littermates and explore the whelping box. Start introducing softened puppy food around day 21-25.
• Week 4-5: Full weaning begins. Puppies are active, playful, and learning bite inhibition from littermates. Begin early socialization with gentle handling, novel surfaces, and sounds.
• Week 5-8: Critical socialization window. Expose puppies to a variety of people (men, women, children), environments (indoor, outdoor, different surfaces), sounds (vacuum, doorbell, traffic), and experiences. This period shapes lifelong temperament.

Socialization window: The critical socialization period is 3-14 weeks, with peak sensitivity from 6-8 weeks. Puppies should meet dozens of people, experience car rides, encounter novel objects, and begin basic handling (nail trimming, ear examination, mouth inspection) before going to their new homes.

Weaning age: 5-6 weeks (gradual process; most puppies fully weaned by 6 weeks)

Go-home age: 8 weeks minimum. Many breeders prefer 9-10 weeks to allow extended socialization and temperament evaluation.

Adult size achievement: Chinooks reach approximately 80% of adult height by 12 months but continue filling out and maturing through 18-24 months. Full physical and mental maturity is not achieved until 4-5 years of age.

Structural evaluation timing: Evaluate puppies at 8-10 weeks for initial structure and movement. Re-evaluate at 6 months, 12 months, and 18 months as the dog matures. Do not make final breeding decisions based on puppy structure alone; Chinooks change significantly during the long maturation process.

Breeding Economics

Breeding Chinooks is rarely profitable when all costs are properly accounted for, particularly given the small average litter size of 6 puppies and the conservation priorities that may require outcrossing to distant bloodlines (increasing travel or AI costs).

Costs per litter (assuming natural whelping):

Health Testing (Dam): $475 initial year, $75 annually thereafter for eye exams

Stud Fee: $500-$1,500; average $1,000

Progesterone Testing: $200 (3-4 tests to accurately time breeding)

Prenatal Vet Care: $300 (ultrasound confirmation, wellness exams, X-ray for puppy count)

Whelping - Natural: $500 (supplies, veterinary support, potential oxytocin or calcium)

Whelping - C-section: $1,800 (emergency surgical delivery, anesthesia, hospitalization)

Puppy Vet Costs: $150 per puppy x 6 puppies = $900 (wellness exams, first vaccinations, deworming, microchips)

Food & Supplies: $400 (increased food for dam during pregnancy and lactation; puppy food through 8 weeks; bedding, toys, cleaning supplies)

Registration & Marketing: $200 (AKC litter registration, individual puppy registrations, advertising, website, puppy packs)

Total cost (natural whelping): ~$3,975

Total cost (C-section): ~$5,275

Revenue:

Average Puppy Price (Pet Quality): $1,800

Average Puppy Price (Show/Breeding Quality): $2,500

Average Litter Revenue (6 puppies at $1,800 each): $10,800

Net per litter:

• Natural whelping: $10,800 - $3,975 = $6,825
• C-section: $10,800 - $5,275 = $5,525

These figures assume all puppies are sold, no major complications, and do not account for the breeder's time investment (hundreds of hours in puppy care, socialization, and buyer screening). Chinook breeders often reinvest profits into health testing, show campaigns, and breed education rather than treating breeding as a primary income source.

Economic realities for rare breed conservation: Many Chinook breeders operate at reduced profit margins or even losses when pursuing genetically valuable but geographically distant breedings that require expensive frozen semen shipments or travel. The conservation priority sometimes outweighs economic optimization.

Frequently Asked Questions

How many puppies do Chinooks typically have?

Chinooks average 6 puppies per litter, with a typical range of 3-9 puppies. Most litters fall between 5-7 puppies. The breed's smaller litter size compared to other working breeds reflects its limited gene pool and conservation status.

Do Chinooks need C-sections?

Approximately 20% of Chinook litters require C-section delivery, which is higher than the 10-15% rate for similar-sized working breeds. Natural whelping is the norm, but breeders must be financially and logistically prepared for emergency surgical intervention. Uterine inertia (5.36% of females) and hydrops fetalis are the most common complications requiring C-section.

What health tests are required for breeding Chinooks?

All breeding Chinooks must complete four mandatory tests for CHIC certification: Hip Dysplasia (OFA or PennHIP), annual Eye Examination (OFA CAER), MDR1 Genetic Test, and Chondrodysplasia Genetic Test. Total cost is approximately $475 for the initial year, with $75 annually for eye re-examinations. Additional recommended tests include cardiac evaluation and thyroid panel.

How much does it cost to breed Chinooks?

Total cost per litter ranges from $3,975 (natural whelping) to $5,275 (C-section), including health testing, stud fee, prenatal care, whelping, puppy veterinary care, food, and registration. With an average litter of 6 puppies sold at $1,800 each (pet quality), revenue is approximately $10,800, yielding net profit of $5,525-$6,825 before accounting for the breeder's time investment.

At what age can you breed a Chinook?

Female Chinooks should not be bred before 24 months of age, after completing OFA hip certification. Males can be bred at 18-24 months, preferably after preliminary OFA evaluation. Chinooks mature slowly (full maturity at 4-5 years), so breeding decisions should not be rushed. Maximum recommended litters per female is 5, with retirement at 7-8 years.

How much do Chinook puppies cost?

Pet-quality Chinook puppies average $1,800, while show or breeding-quality puppies command $2,500 or more. Prices reflect the extensive health testing, limited availability, and conservation status of this rare breed. Reputable breeders often have waiting lists due to small litter sizes and infrequent breedings.

What are the most common health problems in Chinooks?

The most prevalent health conditions in Chinooks are cryptorchidism (14.63% in males), seizure disorders including epilepsy and dyskinesia (8.37%), hot spots/allergic dermatitis (8.37%), and hip dysplasia (7.11%). All breeding stock must be health tested for hips, eyes, MDR1 mutation, and chondrodysplasia. Dogs with cryptorchidism, seizures, or poor hip scores should not be bred.

Is breeding Chinooks profitable?

Breeding Chinooks can be modestly profitable ($5,525-$6,825 net per litter after expenses) but should not be undertaken primarily for income. The breed's conservation status often requires breeders to prioritize genetic diversity over convenience, which can increase costs (distant stud dogs, frozen semen, travel). Many breeders reinvest profits into health testing, show campaigns, and breed education. The primary reward is preserving one of America's rarest native breeds.

Why is the Chinook so rare?

The Chinook nearly went extinct in the 1980s when only 28 dogs remained worldwide, with just 11 suitable for breeding. This genetic bottleneck has permanently limited the breed's population size and genetic diversity. Despite recognition by the AKC in 2013 and dedicated conservation efforts, fewer than 1,000 Chinooks exist globally. Every breeding decision carries conservation significance, requiring coordination with the Chinook Club of America to maximize genetic diversity and population health.

Can Chinooks be any color other than tawny?

No. The Chinook breed standard strictly requires tawny coloration ranging from honey to deep reddish-gold, and any other coat color is a disqualification from breeding and showing. Dark shading on the ears and muzzle is highly desirable. While genetic testing has revealed that some Chinooks carry recessive genes for black and tan or solid black, these colors are not acceptable and dogs producing non-tawny puppies should be removed from breeding programs.
