Dog Breed Health Guide
Every breed carries specific health predispositions. Know what conditions your dog is most at risk for — so you can catch signs early and insure before they appear.
This content is for informational purposes only and should not replace professional veterinary advice. Always consult a licensed veterinarian for concerns about your dog’s health.
Selective breeding has made dogs extraordinarily diverse — but it has also concentrated certain genetic traits that predispose specific breeds to predictable health conditions. Understanding your dog's breed profile isn't just interesting. It's the foundation of proactive, cost-effective care.
This guide covers the most common health risks by breed group. Whether you own a French Bulldog, a German Shepherd, or a Labrador Retriever, knowing what conditions to watch for lets you act early — when treatment is less complex and less expensive.
One important caveat: breed predispositions are statistical tendencies, not certainties. Your dog may never develop the condition your breed is known for. But if they do, and you're not insured, you may face a $3,000–$10,000+ bill you weren't prepared for. Fetch Pet Insurance covers hereditary conditions — but only if you enrol before they're diagnosed.
Pre-existing conditions aren't covered
Pet insurance only covers conditions that develop after your policy starts. If your Labrador develops hip dysplasia before you get insured, that condition is excluded permanently. The best time to get covered is now — while your dog is healthy.
Large Breeds
Health risks for large and giant breeds
Large breeds (50+ lbs) are predisposed to joint disease, bloat, and heart conditions. Their size increases surgical risk and costs significantly.
Hip Dysplasia — Labs, Shepherds, Goldens
Malformed hip joints lead to pain and arthritis. Common in retrievers and shepherds.
Bloat (GDV) — Deep-Chested Breeds
Great Danes, Dobermanns, and Weimeraners have significantly elevated bloat risk.
Dilated Cardiomyopathy — Dobermann
DCM affects Dobermanns at extremely high rates — often developing silently.
Elbow Dysplasia — German Shepherd
Malformed elbow joints causing lameness — common in German Shepherds and Labs.
Degenerative Myelopathy — German Shepherd
Progressive spinal cord disease — similar to ALS in humans. No cure.
Osteosarcoma — Large Breeds
Bone cancer is far more common in large and giant breeds. High amputation and chemo costs.
Small Breeds
Health risks for small and toy breeds
Small breeds often live longer than large breeds, but they're predisposed to dental disease, luxating patellas, and collapsed tracheas.
Dental Disease — Toy Breeds
Small mouths mean crowded teeth. Periodontal disease causes pain and systemic illness.
Luxating Patella — Pomeranians, Chihuahuas
Kneecap dislocation is common in toy breeds — ranges from mild to requiring $2,000+ surgery.
Tracheal Collapse — Yorkshire Terriers
A honking cough is the hallmark sign. Managed medically or surgically in severe cases.
Mitral Valve Disease — Cavaliers, Dachshunds
Heart murmurs develop in most Cavalier King Charles Spaniels by age 10.
Hydrocephalus — Chihuahuas
Fluid on the brain — common in toy breeds, particularly dome-headed Chihuahuas.
Legg-Calvé-Perthes Disease — Small Breeds
Deterioration of the hip joint in dogs under 20 lbs — most common in Yorkies and Maltese.
Flat-Faced Breeds
Brachycephalic breeds: French Bulldogs, Pugs, Bulldogs
Flat-faced breeds have compressed airways that lead to a cluster of breathing and structural problems. They are among the most expensive breeds to insure and treat.
BOAS (Brachycephalic Obstructive Airway Syndrome)
Stenotic nares, elongated soft palate, and narrow trachea — surgery often needed.
Overheating / Heat Stroke Risk
Flat-faced dogs overheat much faster and can't pant efficiently. A genuine danger in summer.
Eye Problems — Cherry Eye, Proptosis
Prominent eyes are prone to injury and cherry eye prolapse, requiring surgical correction.
Spinal Issues — French Bulldogs
Hemivertebrae and intervertebral disc disease (IVDD) are common in French Bulldogs.
Dental Crowding
Compressed jaw means severely crowded teeth — dental disease often starts early.
Skin Fold Dermatitis
Moisture in facial folds breeds bacterial and yeast infections requiring ongoing care.
Working & Active Breeds
High-energy and working breed health risks
Working and sporting breeds are built for activity — but that same athleticism creates specific injury and orthopedic vulnerabilities.
CCL / ACL Tears — Active Breeds
Labrador Retrievers, Rottweilers, and Golden Retrievers have the highest CCL rupture rates.
Progressive Retinal Atrophy — Border Collies
Hereditary blindness that progresses slowly — genetic testing can identify carriers.
MDR1 Gene Mutation — Collies
Drug sensitivity that makes many common medications toxic. Test before treating.
Subaortic Stenosis — Golden Retrievers
A heart defect causing a murmur — ranges from mild to life-threatening.
Genetic Conditions
Hereditary conditions across all breeds
Some conditions cross breed lines — they're inherited regardless of breed and can appear in mixed-breeds too.
Von Willebrand Disease
A clotting disorder — Dobermanns are at highest risk. Can turn minor surgery fatal.
Hereditary Cataracts
Early-onset cataracts across multiple breeds — genetic testing can identify risk before breeding.
Osteochondrosis (OCD)
Abnormal bone development in joints — causes lameness in young, rapidly-growing dogs.
Addison's Disease
Adrenal insufficiency — often called the 'great pretender' for how many conditions it mimics.
Screening & Testing
Health screening and genetic testing
Proactive screening can identify conditions before they become symptomatic — giving you more treatment options and lower costs.
DNA Health Testing
Tests like Embark screen for 200+ genetic conditions. $100–$200 one-time cost.
Hip & Elbow OFA Evaluation
The gold standard for orthopaedic screening in breeds predisposed to dysplasia.
Cardiac Screening
Annual cardiac auscultation is recommended for Cavaliers from age 1.
CERF / CAER Eye Exam
Annual eye exam by a veterinary ophthalmologist — essential for herding breeds.
