My boxers Ozzie and Roo, have been up to no good at night. My veternarian described this as the equivalent of a "teenage rebelious phase". A little history...Ozzie is a 2-year-old-male and Roo is a 1-year-old female. They are crate trained for when we are not at home. Anyway, during the night while us humans are asleep they have developed some rather destructive behaviors that include, but are not limited to...chewing personal belongings, getting into the trash can and dragging it throughout the rest of the house and chewing furniture. We have never actually caught them in the act of the bad behavior, so finding the proper corrective method has been hard. There are several chew toys available to them at all times. This all began 1-month prior to Roo's first heat(which took place on her first birthday, 12/20/04) and has been continuing at least weekly since. Please, any advice or similar situations would offer much needed hope!
