Welcome!
Welcome! You picked an awesome breed of dog. Boxers are a lot of fun and are very humerous. I have a 7 yr old female that never chewed up anything. I always had toys and chews around for her though, very important. BUT we now have a 5 mo. old boy that chews on everything! So yes, I would make sure you don't have anything down that you don't want chewed up. It is definately not a good idea to leave a puppy unattended in a room. It's amazing the damage they can do in two minutes. Also, if you haven't started so, I would definately crate train. You can find many wonderful forums and articles here at Boxerworld for any topic you need to research. Good luck and congratulations!
