hello, my 6 month old aussie shep mix was spayed aabout 3 weeks ago, since then we have noticed her biting ather hip, a few days ago we noticedher limping and when i checked her out i noticed a largepatch of hair bitten out of her righ hip area. we took her to the vet they said possible hip dysplagia. after her manipulated her hips she could hardly walk. after thinking about it all, i realized that ahe has only been biting herselfsince she was spayed, has anyome heard of a vet injuring the dog during her spay surgery??? In the mean time i wastold to give her baby asprin. i am so worried
