I caught Bentley hiding his heartgard cube and now I wonder if he has been doing this all along and not taking them. He tested neg on his last checkup. Just wondering how long this has been going on. He comes up and takes them from me and walks off kind of slow, turning and looking over his shoulder, then I saw him hide it behind a door! All the other dogs I have had gulped them down whole. I don't think he likes them. Do your malts take theirs ok?
