Most Common Dog Breeds With Hip Dysplasia: Risk List

Hip dysplasia turns up most often in large and giant breeds. German Shepherds, Labrador Retrievers, Golden Retrievers, Rottweilers, Bernese Mountain Dogs, Saint Bernards, Newfoundlands, Great Danes and the whole mastiff family, English Mastiff, Bullmastiff, Neapolitan Mastiff, Dogue de Bordeaux, are the names that dominate orthopaedic screening databases. Bulldogs and Pugs are heavily represented despite being compact dogs, and small breeds down to the Chihuahua can be diagnosed with it too.

Breed is a risk factor, not a verdict. Plenty of German Shepherds live out long lives on sound hips, and plenty of mixed-breed dogs with no giant-breed ancestry develop dysplastic joints. What breed gives you is a reason to look earlier, screen sooner, and build a joint-protective routine before a limp ever appears.

Why certain breeds end up on the list

Hip dysplasia is a developmental problem, not an injury. The hip is a ball-and-socket joint, and in a well-formed hip the femoral head sits deep and snug in the acetabulum. In a dysplastic hip the fit is loose. That laxity lets the head slide and grind against the rim of the socket instead of rotating cleanly inside it. Over months and years the cartilage wears, the bone remodels at the edges, and the joint ends up with osteoarthritis, which is the part most owners actually see.

Three things stack the odds:

Genetics. Hip conformation is polygenic: many genes each contributing a small amount. That is why it does not follow neat inheritance patterns, why two parents with excellent hip scores can still produce an affected puppy, and why reducing it in a breed takes generations of disciplined screening rather than a single test.

Growth rate and body mass. A puppy that will weigh 140 pounds has to build a skeleton fast, and the soft tissues stabilising the hip, joint capsule, round ligament, the gluteal and pelvic musculature, have to keep pace with bones that are lengthening quickly. Giant breeds grow for longer and carry more load across a joint whose fit is still being finalised.

Body condition and early loading. A long-running lifetime feeding study in Labrador Retrievers found that littermates kept lean throughout life showed radiographic signs of hip osteoarthritis later than those fed more generously. Carrying extra weight does not create a dysplastic hip, but it changes how hard an imperfect one is worked every single day.

Conformation matters too. Breeds built with heavy forequarters, a short croup, or a dramatically angulated rear load the hip differently from a square, moderate dog: part of why bulldog-type breeds appear so high in screening results despite modest body weight.

The breeds that show up most often

The Orthopedic Foundation for Animals publishes breed-by-breed hip evaluation results, and the same groups recur year after year. Here is how the risk tends to cluster:

Group	Representative breeds	Why risk runs high
Giant working and mastiff types	English Mastiff, Bullmastiff, Neapolitan Mastiff, Dogue de Bordeaux, Saint Bernard, Newfoundland, Great Dane	Extreme body mass over a long growth period; heavy soft-tissue loading before skeletal maturity
Large herding and sporting breeds	German Shepherd, Labrador Retriever, Golden Retriever, Rottweiler, Old English Sheepdog	Very large gene pools with long-standing hip laxity; high activity levels expose subtle instability
Mountain and draft breeds	Bernese Mountain Dog, Leonberger, Greater Swiss Mountain Dog	Giant-breed growth plus a deep, heavy-bodied build
Brachycephalic and bulldog types	Bulldog, French Bulldog, Pug, Boston Terrier	Pelvic conformation and shallow sockets; rank among the highest in screening results despite moderate size
Thick-set spitz and terrier types	Chow Chow, American Staffordshire Terrier, Shar-Pei	Dense musculature and compact, heavily loaded hindquarters
Toy breeds	Chihuahua, Pomeranian, Yorkshire Terrier, Miniature Poodle	Lower incidence, but hip disease does occur and is often missed or mistaken for other joint problems

Mixed-breed dogs inherit whatever their parents carried. A shepherd-cross or a mastiff-cross should be treated as a large-breed risk profile until a veterinarian says otherwise.

Mastiff hip dysplasia: what owners notice first

Mastiffs deserve their own paragraph because the signs are so easy to write off as personality. Mastiffs are not fast dogs. They lounge, they lean, they take stairs deliberately. So the early signals of hip trouble read as normal mastiff behaviour until they are not.

The symptoms owners of mastiffs and other giant breeds most commonly report:

• A bunny-hop, both hind legs moving together at a trot or up stairs, rather than alternating
• Reluctance to rise, especially after a long sleep or on a cold morning, with a stiff first few steps that loosen up
• A narrow or swaying rear stance, hocks drifting close together
• Sitting sloppily with one leg kicked out to the side
• Visible loss of thigh and rump muscle, often with the shoulders building up to compensate
• An audible click from the hip at the walk
• Hesitation at jumps, car doors and stairs that used to be nothing
• Snapping or flinching when the hindquarters are handled or the hip is extended

In giant breeds these signs can appear young, sometimes in the first year, while the dog is still growing, and then again later in life as osteoarthritis accumulates. The in-between years can look deceptively quiet. If you own a mastiff and any of the above sounds familiar, that is a conversation with your veterinarian, not a wait-and-see.

Small breeds are not exempt: including Chihuahuas

Search any veterinary forum for Chihuahua hip problems and you will find owners surprised that it is possible at all. It is. Hip dysplasia is less common in toy breeds, but it occurs, and small size can actually delay diagnosis: a four-pound dog hides a sore hip easily because so little load passes through it.

Two other conditions complicate the picture in small breeds, which is exactly why imaging matters rather than guesswork:

• Patellar luxation, where the kneecap slips out of its groove, is far more common in Chihuahuas, Pomeranians and Yorkies, and produces a skipping hind-limb gait that owners often attribute to the hip.
• Legg-Calvé-Perthes disease, a degeneration of the femoral head seen in young toy and small terrier breeds, causes hind-limb lameness and muscle loss that can mimic dysplasia closely.

Pugs and French Bulldogs sit in a category of their own: small dogs that appear near the top of hip screening results, a reflection of pelvic conformation rather than body mass. A small dog that limps, skips, or stops jumping onto furniture needs the same diagnostic pathway as a Rottweiler: radiographs and a proper orthopaedic exam.

Screening, diagnosis and the questions to ask

Breed tells you where to look and when to start looking: it never tells you whether your individual dog has dysplastic hips, and only a veterinarian with radiographs can answer that.

Two formal screening systems are used widely. The Orthopedic Foundation for Animals evaluates hip-extended radiographs and grades joint conformation. PennHIP, developed at the University of Pennsylvania, measures passive hip laxity with a distraction technique and can be performed on much younger dogs. Breeders of high-risk breeds should be able to show you results for both parents without hesitation; if they cannot, that tells you something.

In a clinical setting, your vet will watch the dog move, feel for pain on hip extension, assess muscle symmetry and check for an Ortolani sign, a palpable clunk as a loose femoral head relocates, usually under sedation. Radiographs confirm the joint architecture and the degree of arthritic change. From there the plan might involve weight management and rehabilitation, prescribed pain control, or surgical options ranging from juvenile procedures in young dogs to femoral head ostectomy or total hip replacement later on. Those decisions belong with your veterinarian, who has the images and the hands-on exam.

Daily support for a dog in a high-risk breed

For a dog whose breed puts them on this list, the routine you build matters more than any single intervention.

Keep them genuinely lean: ribs easy to feel, a visible waist from above. Swap repetitive high-impact work for controlled, consistent movement: measured leash walks, swimming, underwater treadmill work, and the targeted strengthening a veterinary rehabilitation practitioner can prescribe. Put down traction on slick floors. Use ramps for the car and raised furniture. Build hindquarter muscle deliberately, because musculature is what stabilises a loose joint.

Where anything prescribed is concerned, NSAIDs, injectable monoclonal antibodies, gabapentin, a surgical plan, follow your veterinarian's direction exactly. Nothing in a supplement routine replaces it.

The supplement aisle is where owners get taken advantage of. Kitchen-sink chews with twenty ingredients at trace amounts, proprietary blends that hide how little is actually in there, and marketing budgets that dwarf the evidence behind the label. This is where scepticism belongs.

It is also the context in which a lot of owners of large and giant breeds have moved toward peptides. pawgen makes K9-REPAIR, a BPC-157 and TB-500 formulation for dogs. BPC-157 is a peptide sequence derived from a protein found in gastric juice, and published laboratory research describes effects on angiogenesis, fibroblast migration and connective tissue repair processes in tendon, ligament and muscle models. TB-500 is a synthetic fragment related to thymosin beta-4, an actin-binding protein studied for its role in cell migration and tissue remodelling. That is mechanism, promising, actively researched science that owners are adopting as the stack they run through recovery and rehab periods. Neither compound is an FDA-approved veterinary drug, and nothing here is a claim about what will happen in your dog. Research suggests these pathways are worth understanding; owners report using them alongside, never instead of, the plan their vet set.

What pawgen can state plainly is what is in the bottle: a defined BPC-157 and TB-500 formulation with weight-based reference amounts on the label, third-party testing with certificates of analysis published for every batch, shipping direct to your door, and a 60-day money-back guarantee. Before adding anything to a dog with diagnosed hip disease, particularly one on prescribed medication, a growing puppy, or a pregnant or nursing dog, talk it through with your veterinarian first.

Key Takeaways

• Large and giant breeds dominate the list: German Shepherds, Labradors, Golden Retrievers, Rottweilers, Bernese Mountain Dogs, Saint Bernards, Newfoundlands, Great Danes and the mastiff family.
• Bulldogs, French Bulldogs and Pugs rank high despite modest size, driven by pelvic conformation rather than body mass.
• Chihuahuas and other toy breeds can develop hip dysplasia, though patellar luxation and Legg-Calvé-Perthes disease are more common look-alikes.
• In mastiffs, watch for bunny-hopping, slow rising, a narrow rear stance and quiet loss of thigh muscle.
• Hip dysplasia is polygenic, and growth rate, body condition and early loading all influence how it expresses.
• OFA grading and PennHIP distraction measurement are the established screening routes; ask breeders for both parents' results.
• Lean body condition, traction, controlled exercise and hindquarter strengthening are the foundation of day-to-day management.

If you want to go deeper on a specific breed's joint profile, pawgen's breed health library covers them individually. Batch certificates of analysis for K9-REPAIR are published in the COA archive, formulation and ordering details sit on the product page, and shipping coverage is listed under where pawgen ships.

One last thing worth saying clearly. Your veterinarian owns the diagnosis and owns the treatment plan: the radiographs, the pain management, the surgical decision, the rehab prescription. Breed risk lists like this one exist to tell you when to make that appointment and what to ask once you are in the room. Supplements and peptides, including K9-REPAIR, operate in the space that proper veterinary care creates, never in place of it.
