A dog's four legs work in a coordinated manner to get him from point A to point B, but sometimes the legs don't work quite as they should or the central nervous system doesn't communicate properly with the head, body, or legs. This makes a dog wobble and have problems moving around. This uncoordinated abnormal movement is called ataxia, and there are three general causes in dogs. Knowing more about this abnormal movement will help a dog owner better recognize these problems if they occur.
There are three main causes of ataxia that may occur in dogs, but all affect how well a dog can move around.
