content: Easy to assembleLarge enough for a 100 lb boxer/mastiff mixI leave my pooch in the garage with access to the backyard during the work days. This kennel gives him nice cozy place to curl up on those cold days in the NW. I placed an outdoor heating pad on the bottom and i covered the top and sides with an old rug to provide some "insulation." He appears to like it just fine.If you need to move the kennel around, you might want to have a second person to hold the other end - it isn't heavy, but the sides easily pop out of joint if you drag it. Other than that, no complaints.I haven't closed the door while my dog is in it, so I can't attest to the kennel's ability to hold up against an escape artist...
