What is it?
Hip dysplasia is a malformation of the coxofemoral joint where the head of the femur does not fit correctly into the socket of the pelvis. This joint instability gradually leads to wear, inflammation and osteoarthritis. It mainly affects large breed dogs but can also affect cats.
Commonly observed signs
These signs are neither exhaustive nor specific. Only a veterinarian can establish a diagnosis.
Related signs — each one links to its page:
There is difficulty getting up, abnormal gait (waddling), reluctance to jump or climb stairs, and lameness which may worsen with activity. Over time, muscle wasting in the thighs may appear as well as stiffness after rest.
When to consult without delay
This list does not replace veterinary advice. It gathers situations that justify a prompt consultation.
Causes and risk factors
The main cause is genetic, linked to a hereditary predisposition favoring abnormal development of the joint. Environmental factors such as growing too fast, being overweight or eating an unbalanced diet while growing can make the problem worse.
Large breeds such as the German Shepherd, Labrador or Rottweiler are particularly predisposed. Rapid growth, being overweight, excessive exercise in young animals and a family history increase the risk.
Transmission
It is not a contagious disease, so it is not transmitted between animals or between animals and humans. Transmission is only hereditary, from parents to offspring.
Diagnosis and care
Diagnosis is the veterinarian's responsibility, based on clinical examination and laboratory tests. Care is decided case by case.
If your pet shows signs of lameness or difficulty moving, it is important to consult a veterinarian for a proper evaluation. Only a professional can confirm the cause and offer treatment adapted to the situation.
Prevention
The choice of healthy breeding stock tested against dysplasia in breeds at risk is essential. Maintaining an appropriate weight, providing a balanced diet during growth and avoiding excessively intense exercise in young dogs helps limit the risks.
