Large enough for my 100# lab she has plenty of room to move around in lay any which way she wants, super light so I can move it to different areas if I need to. easy to just slide under the bed like I do for storage or to vacuum. but the best part is the price is amazing! if I bought this at my local pet supply store I would spent every bit of $100. I was able to buy 2 of these 1 for inside and one for outside and not even come close to $100! Great Buy!!!
