Potty training is certainly the most challenging for me. In Ohio its cold right now and breaking a puppy is hard to do. I take her out and she refuses to go. I bring her in and she piddles on the floor. Bad puppy!
My older yorkie has problems at night. Perhaps I should be using a crate for them but I feel so bad doing that. I thought of a belly band but I've not seen one or spoke to anyone that has used them. I have my own office so I take them with me from time to time. I'm sure she'll get it sooner or later, as for Max at 4 yrs I'm not sure what to do.
