So we have had our bernadoodle for 2 months or so now. He is 4.5 months old, and he poops and pees wherever he wants in my house, including the couches. We have tried treats for going potty outside, I have recently started attaching him to me via leash and that seems to work ok, but he still is not telling me when he needs go to outside. My wife has about had it(even though the puppy was her idea). Any tips or advice?
