I have learned other pet supply sites continually change their prices and even worse do not have the products I order in stock. Even though VitaHound's product selection is rather thin they offer great quality products at the lowest prices and they never raise their price when others do. My only grip is the phone support but I have always received immediate responses to my emails, OH one other aspect I love is their coupons, when VitaHound offers discounts via email coupons I don't know how their making money. Any dog owner should try the VitaHound supplement, if you don't mind your dog's larger stools when they go, your dog will feel better, mine stopped itching and shedding.
