My guess is that her condition, since it is in both knees and of two different grades, is congenital (meaning present at birth). Have the vet, after surgery, differentiate as to whether the groove in the bone was so shallow it needed to be deepened (congenital) or whether he was just repairing the soft tissue (more likely injury). Congenital however is not the same thing as hereditary, although many congenital defects are inherited. Really, what you would need to know is (a) whether the problems with the knee is a too shallow a groove which means congenital and (b) whether there are littermates, or full or half siblings (or parents) with the same condition. If so, most likely it was inherited. |
What age would think would be good to have it done since most vets are under the impression that ALL puppies have loose knees to a degree. This is something I would be interested in doing on all puppies.
