Great Bed! I have a pittie/retriever mix and he’s 65lbs and this suits him perfectly. I would definitely recommend sizing up if you have a longer dog so they can stretch out as much as possible. The bed itself is very lightweight which is a plus if your’e trying to move things around. The bottom of the bed is tacky so it helps from it shifting around with movement. Additionally, the thickness of the bed is great, it doesn’t sink when he lays on it so it gives him a lot of support which is so much better than some of the beds i’ve seen at retail stores. Overall I couldn’t recommend this product enough. BUY IT!!
