Dog breeds prone to hip dysplasia: what breeders should screen for

A dog with hip dysplasia does not always cry in pain. For months, sometimes years, the signs are quieter: a reluctance to climb stairs, a bunny-hop gait on the run, a puppy that tires faster than its littermates. By the time the limp is obvious, the joint has already changed in ways that cannot be undone. Understanding which breeds carry the highest risk, and what screening can catch before a litter is ever born, is where the conversation has to start.

In a healthy hip, the ball of the femur sits snugly inside the socket of the pelvis. Hip dysplasia is a developmental condition in which this fit is loose. The ball shifts, the socket is shallow, and the cartilage that cushions the joint wears down under repeated abnormal movement. Inflammation follows, and over time, the joint lays down extra bone in an attempt to stabilise itself. That process is osteoarthritis, and it is progressive. The underlying cause is genetic: a dog inherits a predisposition to poor joint development. But genetics are not destiny on their own. Rapid weight gain, high-impact exercise in puppyhood, and slippery flooring can all accelerate how quickly a predisposed joint deteriorates. The breed determines the starting risk. The environment determines how fast it moves.





Hip dysplasia appears across many breeds, but prevalence data consistently places certain breeds at the top. German Shepherds are among the most studied, in part because of their popularity and in part because the condition is common enough in the breed to have shaped breeding conversations for decades. Labrador Retrievers and Golden Retrievers, both heavy, active dogs bred for sustained physical work, show high rates in screening databases. Rottweilers carry significant risk, as do Saint Bernards and Bernese Mountain Dogs, where the combination of large frame and rapid early growth puts early stress on developing joints. Among breeds common in Indian homes, the Labrador is the most relevant. It is also one of the most frequently overbred and poorly screened breeds in the Indian market, which compounds the risk for buyers who do not ask the right questions. Larger Indian breeds such as the Rajapalayam and the Gaddi are not exempt, though systematic prevalence data for Indian native breeds is limited. The Mudhol Hound and the Chippiparai, being lean sighthound types, carry lower structural risk by build, but no breed is entirely free of it. Medium breeds including Bulldogs and Pugs carry hip dysplasia risk alongside their other structural concerns. Small breeds are affected less often, but it does occur.

Screening for hip dysplasia happens before breeding, not after. A responsible breeder does not wait for a dog to show symptoms. The standard tool is radiographic evaluation: X-rays of the hips taken under sedation, with the dog positioned in a specific way so the joint can be assessed accurately. Two main systems are used internationally. The Orthopedic Foundation for Animals grading system, known as OFA, evaluates the hip at two years of age and assigns a rating from Excellent through Fair to the dysplastic grades. The PennHIP method measures joint laxity, the looseness of the ball in the socket, and can be done from sixteen weeks of age, which allows earlier decisions. In India, formal breed health registries equivalent to OFA are not yet established at scale, but breeders working with the Kennel Club of India and those connected to international breed clubs do use radiographic screening. A breeder who cannot show you screening results for both parents is not a breeder who has done the work. Screening does not eliminate the condition from a line in one generation. Hip dysplasia is polygenic, meaning many genes contribute, and even two screened parents can produce an affected puppy. What screening does is reduce the probability over generations, and it does so meaningfully when applied consistently across a breeding programme.



The questions matter as much as the answers. Ask whether both parents have been radiographically screened for hips, and ask to see the documentation. A verbal assurance is not documentation. Ask what the breeder does if a puppy from their litter develops hip dysplasia: a breeder who has thought about this will have an answer. Ask about the puppy's diet plan and whether the breeder advises against high-impact exercise in the first year, because both affect how a predisposed joint develops. Ask whether the puppy's grandparents were also screened, because a single generation of screening tells less than a pattern across the line. If a breeder cannot answer these questions or becomes defensive when asked, that is information. In a market where many litters are produced without any health testing, the buyer's willingness to ask is one of the few checks that exists. A dog with hip dysplasia can live a full life with the right management, but that life will involve vet visits, pain monitoring, and decisions that are easier to make when you knew the risk going in.
