The Hartz stuff is not the best IMO, tried it a long time ago and it was a bit too runny and didn't lather well, then still felt like it would not rinse out. Who knows, they may have improved the formula since I last used it?? I use Four Paws Oatmeal Shampoo. It is in a tan bottle with a BOXER on it! Great smell, lathers very well and rinses clean and leaves Killian's coat looking great! People shampoo is not a good idea of course, as it is PH balanced for people and not doggies and can mess up their skin...
