We adopted an 8-month-old male boxer 3 weeks ago and he was doing wonderfully in his crate - no whining, etc. We got a larger crate because he was growing FAST and moved it into another room. He was fine for about a week. Yesterday, when we go home, it looked like someone had broken into our house. Stuff was EVERYWHERE! Last night, he chewed part of the wires off his crate. We both work and are gone for 8-9 hours a day. He had been doing great when we first got him. HELP! Any suggestions? Would a plastic crate (more like the traveling crates) be better? I give him peanut butter in a kong plus a couple of toys to keep him occupied.
