I was skeptical about buying this house for my Pit because I didn't know if it'd be big enough and because it was plastic. I figured my 1 year old puppy would go to town trying to see how quickly he could destroy it. From what I've observed so far I think the house will be able to handle my dog...and my dog will be able to handle the house. No problems yet! As soon as I put the 1st piece down, which was the floor, my dog instantly laid on it like it was everything he'd been waiting for! LOL! I actually snapped the house pieces together around him because he wouldn't move. He's 60 lbs and long. I wish the house was just a bit longer and the floor more firm. Other than that it's perfect for him. He likes to curl up anyway. Plus when he lays flat on his side he still fits inside. Since the floor isn't all that sturdy I took his bean bag and put it in there. That made it his official place to dwell. The first day I left him outside I walked back in the house, he normally tries to come back in with me, but this time he just went in his house, watched me go in, and laid down. I like the house!!! He loves it!
