My 3 goldens were continually suffering from diarrohea which the vet was unable to discover the reason for. I was using VIP dog rolls and had noticed some changes in the smell and texture of the rolls, so, under advice from my vet, I have used Tucker Time for the past 12 months and no more diarrohea. The kids love it. They have only Tucker Time (chicken and garlic rolls) and senior Pedigree dry food. They certainly aren't fading away. I often give it to the yorkies as well, and they love it.
Some vets sell it, PetStock sells it and my local One Stop Pet Shop. It isn't available in supermarkets.
I purchase it from my local One Stop Pet Shop and the owners are dog show people. They have assured me the product is free of undesirable additives, and, in fact, have stopped selling any other type of dog food because of the additives.
