if so, how are they doing? i've had ****' on this for about 2 weeks. i just noticed last night his hair is smooth as butter and so shiny. i've noticed that his stools are a little smaller and seem firmer. i was worried that this was upsetting his tummy because i had read alot of complaints about that in other dogs. but when i had him outside over the w/e he did attemp to eat any grass. so i am assuming his tummy is okay?
