The vet said my dog sprained her ACL?

i would think that since you know your dog better than your vet does, no matter how much schooling he has had, he would at least listen to your concerns and give them some sort of weight in his diagnosis and examination. i suggest you find a vet that not only cares about your animal but sees you and your concerns as an important part in the treatment. your dog can't speak for herself, you can speak for her, find a vet who will listen to you. does that make sense?
