My vet told me that between 4-6 months Yorkies will regress in their potty training for a few weeks and then when they go back to behaving it will "stick". His actual words were, "they get a case of the dumb-a$$". So far, I have found this to be true with all of mine. Peanut is 6 months old and was doing very well with potty training and sure enough about 3 days ago, he caught that nasty dumb-a$$ virus and I feel like we're back to square one again.Just be consistant & patient.
