They are 3 years old and from the same litter. They have been neutered. They have not fully resolved the alpha issues yet. The most probable alpha is the one who is "going" in the room. He also goes in the morning on the morning walk. But he is then crated, and goes within 3 hours in his crate. We have a room in the house that we have their crates in and they have plenty of toys. They weren't crated for a very long time but this problem may have started when one of them got gardia? We went away with them and left them in the house and no problem. We started crating them again to find out which one was the culprit.
