What could cause rear limb muscle weakness in a older Labrador?

Answer by  ryark (243)

Always consult your veterinarian when you have concerns about your dog's health. Common reasons for rear limb muscle weakness are hip dysplasia, arthritis in the hips, knees, hocks, and spine.If your dog seems to wobble or "walk like a drunken sailor," this is a strong sign of spinal cord damage.

This does not necessarily have to be about Muscles. It is most likely Arthritis in the Hips and Joints of the rear legs. Please make sure your lab has a comfortable bed to sleep in, daily walks and Pain medications.This is common to large Labs.

Many things, including a ligament injury, arthritis, or hip dysplasia can cause our older (and larger) canine friends to walk with some trouble. The only way to be sure what's going on is to see your vet!

Hip dysplasia will cause this in many breeds of large, older dogs. It is wearing down of the joints. Sometimes hip replacement is recommended. Sometimes medication helps for a while.
