Hi, just reading through some posts, and this one caught my eye. Most kennels know that a slight loss of appetite is inevitable and tell the customers as such(I do….) I try to wait till the next day to see if the new dog will eat as this being a natural survival instinct for a dog to eat when hungry. Always rare exceptions of course...another story... Anyway, may I suggest to help with the diarreah with the supplement of adding a teaspoon or so of pumpkin to the 'normal' food the dog is used to. A watered down version of a good canned food over the kibble also has done the trick with boarded dogs as well. Start off with half the kibble and then increase with dog's desire to continue so that the kibble will not go to waste as it is wet and bloated and will one will have a dish of bacteria if left out....Just talk it over with the attendant or Doctor as such.
