In the afternoon when it’s especially hot the babies get Kongs with Frozen peanut butter and yogurt. Takes them longer to eat and must be refreshing. They sure know what I’m carrying and get so excited!! Biting is much better 😀 Although they were not as bad as some other litters. Like kids they need to know good manners😀 They haven’t gone potty in the house in weeks and the babies who have gone home have easily caught on to what door and where in the yard they need to go, so smart!! So eager to please!!
