Hip dysplasia

On urgency, this record says: “Nothing about it is time-critical, but most of what an owner can influence happens before 18 months and cannot be recovered afterwards.

Written by Sunny Luthra and sourced from the veterinary literature. Not yet reviewed by a practising veterinarian. It is guidance for recognising and deciding, not a substitute for examining your dog.

Hip dysplasia is two problems wearing one name.

In a young dog it is a growth and conformation problem, a hip joint that did not form properly. In an older dog it is an arthritis problem, the wear that loose joint has caused over years.

Almost everything an owner can influence happens in the first stage, which is over before most dogs show a single sign.

What is actually wrong

A healthy hip is a ball sitting snugly in a socket. In dysplasia the fit is loose, the socket is too shallow, or the ball is not properly seated, or both.

That looseness means the joint surfaces grind rather than glide. The body responds by remodelling bone and inflaming the joint, and over time that produces osteoarthritis.

It is largely inherited, and most common in large and giant breeds, German Shepherds, Labradors, Golden Retrievers, Rottweilers, Saint Bernards, though it occurs in smaller dogs and in indies too.

What you can actually influence

The genetics are fixed. How badly the genetics express is not.

Overnutrition and rapid growth in large-breed puppies, alongside excess calcium, are established risk factors for developmental orthopedic disease. A puppy that grows too fast is asking an immature skeleton to carry a body it has not caught up with.

This is the whole of the prevention story, and it happens before 18 months:

  • Keep a large-breed puppy lean. Not thin, lean. You should feel the ribs easily. This is the one place where the instinct to feed generously is the instinct to resist
  • Feed a large-breed puppy formulation, which is designed to moderate growth rate rather than maximise it
  • No calcium supplements. Puppies absorb calcium passively and cannot regulate intake, so excess goes in regardless, and excess calcium is directly associated with developmental orthopedic disease
  • Avoid high-impact exercise while growing. Repeated jumping, long runs on hard surfaces, and forced exercise before the growth plates close
  • Non-slip flooring. Puppies skidding on tile and marble is not harmless for a developing hip

If you are choosing a puppy: ask about hip scoring in the parents. It is not common practice among Indian breeders, and asking anyway is one of the few pressures that changes breeding behaviour.

The signs, by age

Young dogs, four months to two years:

  • Bunny-hopping, both hind legs moving together when running. This is the classic sign and it is quite specific
  • Reluctance to run, jump or climb stairs
  • Difficulty rising after rest
  • A swaying, loose-looking back end
  • Sitting with the legs out to one side rather than squarely
  • Audible clicking from the hips

Older dogs, the arthritis stage:

  • Stiffness after rest, easing with movement
  • Reduced activity, shorter walks
  • Visible muscle loss over the hindquarters, sometimes with the front end looking overdeveloped by comparison as weight shifts forward
  • Difficulty with stairs and cars
  • Irritability when handled over the hips

Many affected dogs never limp, because both hips are involved equally and there is no good side to favour. Waiting for a limp is how this gets missed for years.

Diagnosis is a physical examination plus radiographs, usually under sedation so the hips can be positioned properly.

Management

For most dogs this is not a surgical condition. It is an arthritis management problem, and the same layered approach applies.

Weight, first and most. In an overweight dysplastic dog, nothing else you do will match the benefit of getting the weight off.

Controlled, consistent exercise. Regular moderate movement maintains the muscle that stabilises a loose joint. Muscle is the joint's support structure, and a dog rested into inactivity loses the thing holding the hip together. Swimming is excellent where available.

Pain management, properly. Veterinary NSAIDs as a baseline, often with additional medication, and never human NSAIDs, which are toxic to dogs.

Physical rehabilitation, increasingly available in Indian cities and genuinely valuable for this condition specifically.

Home changes: rugs over slippery floors, a ramp instead of jumping into the car, a supportive bed, short nails.

Surgery is worth discussing for young dogs with severe disease, or for dogs whose pain cannot be controlled medically. Options range from procedures that alter the growing pelvis in young puppies to total hip replacement in adults. It is a specialist conversation, and it is not the default.

What to expect

Most dysplastic dogs, managed well, live comfortable and active lives. The disease is progressive, but the rate varies enormously and the difference between a lean, well-muscled, well-medicated dog and an overweight sedentary one is measured in years.

Reassess periodically. A plan that suited a five-year-old is often under-treating at nine.

The bottom line

Hip dysplasia is inherited, but severity is not fixed at birth, how a large-breed puppy is grown changes how badly it expresses.

Keep the puppy lean, feed a large-breed puppy diet, skip the calcium entirely, and go easy on high-impact exercise until the growth plates close.

In an adult, this becomes an arthritis problem and the answer is the arthritis answer: weight off, muscle on, pain properly controlled, and rugs on the floors your dog is slipping on.

Bunny-hopping in a young large-breed dog is worth investigating even in the absence of any limp. It is one of the more specific early signs there is.

Near this one

  1. ArthritisA dog that has stopped doing things it used to enjoy is telling you it hurts, not that it is old. Weight loss outperforms every drug available.
  2. Kidney diseaseSilent until roughly two-thirds of function is gone. Increased drinking is the earliest visible sign, and the SDMA blood marker finds it months before creatinine does.
  3. ObesityAround 59% of dogs are overweight and most of their owners do not think so. The most treatable thing on this shelf, and the least treated.
