Silas has started this new behavior that is started to become to over the top. In the mornings around the same time the boys go outside to have their breakfast, go to the bathroom, and wait for us to get up. My husband and i work night shift so we would sleep until around noon. For the past week Silas has gotten into the habit of howling and whining while he is outside. The first time he did it was because my husband got home one morning, let them out, and forgot to put the food out. But ever since then the food has been out, they have water and he just howls, whine, and howls some more. We live in a duplex on the air force base and I'm starting to get worried that our neighbors are going to complain. There isn't a reason for him doing it. He has all he needs, plus we have their outside chew toys out there...we just bough two new toys and replaced two of the old ones. Also, Koda is out there with him and Koda isn't howling or whining. It just makes no since. Any ideas to how to get him to stop?
