I have not had my dog all that long, and when I leave for the day to go to work I am afraid what I might find when I return. He starts to look anxious before I have even left the house, and I can hear him crying from my driveway. For the past few days I have come home to shredded pillows, chewed up shoes and even poop! I was told that my dog was totally housetrained, so when I called the breeder she said that maybe my dog was suffering from separation anxiety. How do I stop him from behaving this way. I feel terrible leaving him on his own!
