My dog loves it! We got this for him in case he's outside and it starts raining. We put shavings inside to give him added warmth and because he didn't like the feel of the plastic floor (he's weird) so far we haven't had rain but our two cats and him go in to get out of the wind. He's 75 lbs and when we were putting it together we could fit inside it together. I'm 5'2" and could sit up almost straight with my head touching the roof. Very spacious! I recommend getting a liner if it snows where you live though!
