I am very frustrated with Buttercup right now. He was very good, I mean very good, with the potty training. Peeing and pooping outside and never made a sound when in his crate/kennel. Two weeks ago, he started peeing and pooping in the house, barks like crazy when he is in his crate, and bites everything he can get his teeth on. I am very frustrated right now because he have never peed or pooped in the house before. He ruined my persian rug today by pooping on it and then smudge his poop all over it. I am FURIOUS and I am on the verge of getting rid of him.
