Large collaspable metal dog kennel. It measures 4' long, 3' high, 2 1/2' wide
We have a medium sized dog (35 lbs) and a small dog and we've kept them both in this at the same time! They both had plenty of room!
We've kept it inside and out and mainly only used it when we were going to be gone from the house for long periods or when someone was dog-sitting for us.
It collaspes down to about 4 - 6 inches tall and flat. Is easily collasped and raised.
My 5 year old is in one of the pictures to give you an idea of the size! (those are only leaves around it and inside of it! It's sitting on our patio right now!)
