Well Gus is about a year, yes. As of lately he has not been chewing on things but has been incredibly hyper and even urinating in the house! He stays on a strict pee schedule usually and has not had an accident in months! It isn't lifting a leg on the wall or slight piddles. He just has a large release wherever he is in the house. I've been taking him out more doing the whole potty training thing all over again but it hasn't been helping. He used to love his crate and now he's just frantic in it. I'm not sure what to do. I took him to the vet to rule out medical issues, still waiting to hear back on lab work. He has not had any major changes to environment and gets a large amount of exercise a day. I really don't know what to do.
