Ok so I rescued a boxer mix when he was about 5 months old... house breaking him was a nightmare however crate training wasnt so bad... we moved when he was about a year old and me and my husband kept the same routing and placed his crate still in our room where it was at the old house. Well he then started hurting himself trying to get out of his crate, we would come home to the crate being bent, his nails bleeding from scratching and i couldnt stand to watch my baby hurt himself... so i quit crating him and let him roam the house. He would have his good days and bad days of chewing anything he could get his mouth on. He was good for about 2 months of not getting into anything while we were gone, however he is back to being my little monster. We were gone for 8 hours yesterday and he literally destroyed the couch. I am not sure what to do as he has plently of toys and as well I have 2 other dogs that are not crated either. however they are both 7 years old. Any thoughts or suggestions? Me and my husband both work second shift for the most part so doggie daycare is kinda hard as we are not able to pick them up.
