I have taken my female Golden retriever here since she was a puppy and have never encountered any of the problems mentioned by a few of the reviewers. My phone calls have always been answered very courteously, I have never encountered anything but very friendly receptionists when I have taken my dog there. She was diagnosed early by Dr. Walls with a torn acl and he was very thorough about explaining all the options to me and recommending a vet surgeon who he thought would do the proper procedures. We followed his advice and she ended up having to have both ACL's repaired and her legs are very healthy today and we are thankful he was able to give us such good advice and recommendations on how to treat. She has had other problems over the years and each one has been handled totally to my satisfaction. I would highly recommend Dr. Walls and the Covington facility.
