Hello, I am posting on behalf of my daughter. She has an 11 month old Pembroke Corgi. Several months ago she noticed that one of his front legs was "knuckling over" occasionally. She took him to the vet and he said that it was a genetic problem with Corgi's where one of the bones grows faster than the other, and it may or may not get worse. Well, it has gotten worse, and another vet said he actually has the problem in both front legs. He has said that to try to correct the problem surgery is necessary, and it needs to be done before the growth plate closes. Cost will be $5,000. !!! If anyone has any knowledge about this condition and the surgery I would appreciate your insight. Also, she has a contract with the breeder saying he was free of genetic defects. She contacted the breeder about this, and her only response has been to say that one of the other puppies in the same litter has this condition also, and that she will not be re-breeding the sire and dam.
