| Really worried now There is a post in behavior about if potatoes are poisonous to dogs. Someone posted a link of things that are poisonus to dogs. One of the items on there is isopropanal, which is one of the ingredients in Bitter Apple. Is Bitter Apple safe for dogs then or what? (the bitter apple that I have is call Grannick's Bitter Apple- water, Isopropanol 20%, bitter principles and extractives) |
