My 8 month old boxer has separation anxiety. When I would leave the house, I would always crate him b/c I thought he was too young to be left alone in the house. He would ALWAYS poop in his crate and I started finding marks in between his paws that would be bleeding. Then one day I came home and he was out of the crate, he actually broke the bars off it and got it. Sooo, next option was to leave him in my room. HUGE MISTAKE! He tore my rug and mattress up, pooped all over, stepped in it, and then ran all over my room. I called the vet and they said they might have medication to put him on. I didn't like the sound of that, so my last resort was to let him roam the whole house w/ my 3 year old lab (who is of course allowed to roam the house b/c of his age). Well, my boxer must feel more comfortable being around my lab when I am gone, because he has not touched ONE thing in the WHOLE entire house. So, you might want to call the vet and see what they suggest. To me, my only options were, medication or leaving him w/ my other dog!
