Dog ate chocolate?

Loss of muscle mass on one leg.

Species: Dog
Breed: Samoyed
Age: 11-15 years
My dog has lost muscle mass on just ONE hind leg and is getting worse everyday. He started by not being able to get up by himself, now he can barely walk. What could this be? Thanks in advance




Online vet, Dr. Marie

Dr. Marie replied:

I'm sorry to hear that Dino is having problems with his leg.

A loss of muscle mass is usually because the dog is not using this leg as much as the other. The cause of that is usually because of pain.

There are a number of things that could be causing this pain. Arthritis is possible. If this is a hind leg, hip dysplasia, which is severe arthritis in the hip could be a cause. It could also be due to a joint problem, or a ligament tear such as an ACL tear in the knee. Although it is not common another cause could be a bone cancer.

It really would be a good idea to have a vet take a look at Dino. They should be able to tell where the source of pain is and hopefully they can prescribe some anti-inflammatory medications that will help.

There is no over the counter medication that I would consider useful for Dino's case.

I hope he is ok!

Dr. Marie.
