I have been going to Healthy Tails on and off for years. Originally I discovered the store because my Grandparents had rave reviews from their own experiences. The store isn't close to me at all, and not convenient enough to buy our dog food there as we are in the SW, but if I lived in Summerlin I'd buy everything here.
Currently I stop in when Afton is working, as she is always full of great information, whether nutrition based or behavior based advice.
