I bought this for my 5 month old boston terrier/english bulldog mix. He is 25 lbs currently and loves his "bed"! Super light so you can move it with no problems. He does try to get out the zippers at times but it has a clip to secure the zippers so that he can't get them open. There are two main openings so that you can have it set up with him getting out the longways (as pictured) or from the longer side where there is also a door. This makes it very convenient to set up in different places in your house. Also, perfect for the car. This was a great investment and he will be able to grow with it.
