Osteochondrosis is a disease that occurs in young growing dogs that results in an interruption to the normal growth of bone and cartilage in the joints. There are multiple forms of osteochondrosis and the resulting effects depend on several factors including:

There is no conclusive scientific evidence to prove that any arthritis supplements work, so why bother?

Because dogs walk on 4 limbs not 2 it takes a lot more pain for them to limp than it does for us to limp. By the time they become lame they are at a much advanced level of degeneration than us weak 2-legged animals. 

Living with Arthritis: your Vet, your Pet and You.

It’s winter, and that’s the worst time for aches, pains and twinges.

Think of arthritis as an incurable, chronic disease.   But, rather than accepting nothing can be done, it means that it’s up to you to make your friend as healthy, happy, and comfortable as possible with the joints that nature, nurture and time have dealt them.

It basically breaks down to a three pronged attack:

  1. how you can make your pet better equipped to live with arthritis
  2. what you, directly, can do to make the disease easier, and
  3. how we, the vets, can help support you both in making life better.
