I have a basset hound who is a little over a year. He has been potty trained for several months. (Literally, zero accidents in the house and did wonderfully going to the door when he needed out). Until recently. He is recently only going to the doe sometimes. Other times he is going pee in the house. This is very sudden as he hasn’t done this, like I said, in several months. He isn’t going in the same spot every time. He isn’t going in his crate when I am gone at work (which is what leads me to believe that it is not a health concern). He has plenty of attention, sleeps with us, and is with us always unless I am at work. There have been no new people, pets, or other changes in our home that I would think prompted this. He’s still so young. I’m at my wits end what do I do?
