I took my 2 GP puppies that I have raised to the vet today because the female started limping on her left front the end of Oct. This was after she had gotten out into the woods next door and we do have a lot of cactus, so i thought she got into something. I found nothing and thought it may right itself if it was sprained etc.... Well my male started limping on the same leg 2 weeks ago. I got them into the vet and he said he didn't feel anything, and if I didn't have a lots and lots of money to spend right now, we should just wait and see if it goes away with a little time. He told me to add fish oil & omega 3 capsules to their food. One of the other littermates limps on the same leg when he does a lot of running..... all the others seem fine, that I contacted or know, and their parents have no issues. Has anyone else had this problem, and if so what did you do?
