Question 1

What causes Legg-Calve-Perthes disease in dogs?

Accepted Answer

The exact cause of Legg-Calve-Perthes disease is unknown, but it involves a disruption of blood flow to the head of the femur (thigh bone). This lack of blood supply causes the bone to die and collapse, leading to severe arthritis and pain. It is believed to have a genetic component, particularly in small and toy breed dogs.

Question 2

What are the early signs of Legg-Calve-Perthes disease?

Accepted Answer

The most common early sign is a gradual or sudden onset of limping on one hind leg, usually appearing when the puppy is between 4 to 11 months old. You may also notice your dog chewing at their hip, showing signs of pain when the hip is touched, or a visible shrinking of the thigh muscles on the affected leg. A veterinarian will typically diagnose the condition using X-rays to look for changes in the hip joint.

Question 3

Can Legg-Calve-Perthes disease be cured without surgery?

Accepted Answer

While mild cases might be managed temporarily with pain medications and strict rest, surgery is almost always required for a permanent cure. The most common procedure is a Femoral Head Ostectomy (FHO), which removes the diseased bone and allows a 'false joint' of scar tissue to form. This surgery effectively eliminates the bone-on-bone pain and restores mobility.

Question 4

Is there a way to prevent Legg-Calve-Perthes disease in my puppy?

Accepted Answer

Unfortunately, there is no known way to prevent Legg-Calve-Perthes disease since it is largely considered an inherited genetic condition. The best preventive measure is for breeders to avoid breeding dogs that have been diagnosed with the disease or have produced affected puppies. Pet owners should ensure their puppies maintain a healthy weight to reduce stress on their developing joints.

Question 5

What is the recovery time and cost for Legg-Calve-Perthes surgery?

Accepted Answer

Recovery from surgery typically takes 6 to 8 weeks, and the procedure generally costs between $1,000 and $3,000 depending on your location. Physical therapy is required during this recovery period to encourage the dog to use the leg and rebuild muscle mass. Most dogs go on to live normal, pain-free, and active lives after a successful recovery.

Question 6

Which dog breeds are most prone to Legg-Calve-Perthes disease?

Accepted Answer

Legg-Calve-Perthes disease primarily affects small, toy, and terrier breeds, typically those weighing under 20 pounds. Commonly affected breeds include Miniature Poodles, Yorkshire Terriers, West Highland White Terriers, Pugs, and Jack Russell Terriers. It is extremely rare for large breed dogs to develop this condition.
