If you find deficits, your veterinarian can help with fine tuning the diagnosis and treatment. A month later she had tripled in size and seemed to be doing fine. Then her ankles became too weak to support her weight and look like they are broken, even though x-rays say they are fine. My vet thinks with the right balance of calcium she will outgrow the problem. Joints require a perfect fit to work properly.
Bones also grow at their ends, close to the joint.
When a bone growth problem is present, it usually shows first at joints. Hocks and carpi become deformed and enlarged. An effected puppy may have an odd angle to the leg, such as being over or under at the carpus. It may be obvious in only one leg, or all legs. If the problem is identified early, fixing the diet is often sufficient for a complete recovery.
