My dog has very sensitive, irritated skin. I'm not sure if it is from allergies (which he has and take an antihistamine for) or?? Who knows with a dog. He eats a very limited food diet so that we can avoid common things dogs are allergic to. My dog has taken one of these per day for a few months. (He is just over 20 lbs) He still has itchy spots he scratches raw. He has always eaten these without a fuss so I assume they taste fine. I just won't continue to purchase since I see no improvement.
