What is it?
Hip dysplasia is a malformation of the hip joint where the femoral head does not fit properly into the pelvic socket. This joint instability gradually leads to wear, inflammation, and arthritis. It mainly affects large dog breeds but can also occur in cats.
The main cause is genetic, related to a hereditary predisposition that favors abnormal joint development. Environmental factors such as rapid growth, excess weight, or unbalanced nutrition during growth can worsen the condition.
Large breeds such as German Shepherds, Labradors, and Rottweilers are particularly predisposed. Rapid growth, being overweight, excessive exercise in young animals, and family history increase the risk.
Commonly observed signs
These signs are neither exhaustive nor specific. Only a veterinarian can establish a diagnosis.
Signs include difficulty rising, an abnormal gait (swaying walk), reluctance to jump or climb stairs, and lameness that may worsen with activity. Over time, thigh muscle wasting and stiffness after rest may develop.
When to consult without delay
This list does not replace veterinary advice. It gathers situations that justify a prompt consultation.
Transmission
This is not a contagious disease, so it does not spread between animals or between animals and humans. Transmission occurs only hereditarily, 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 proper evaluation. Only a professional can confirm the cause and suggest an appropriate approach for the situation.
Prevention
Choosing healthy breeding animals tested for dysplasia in at-risk breeds is essential. Maintaining an appropriate weight, providing balanced nutrition during growth, and avoiding overly intense exercise in young dogs help reduce the risk.
