So, I ordered 3 of these-size medium-for my dogs. I have a full grown pit, a husky/shepherd/coyote mix (about 60lbs), and a 10 month old pit. The size is perfect, the cover is nice and soft and I actually sat on one of them to play with my dogs the first day because they were so comfy. The dogs love them and don't mind sleeping there as opposed to on the bed if they get kicked off in the middle of the night. The only real problem I had with these was that the cover is SUPER thin, which is a huge problem having two very playful pit bulls. As you can probably guess, they ate right through the cover on two of the beds. Now, they have about a billion other beds that they don't eat, the problem with these ones was that during "crazy puppy time" one of them accidentally scratched or bit through the cover, got caught and then decided to tear at it. The beds themselves suffered minimal loss, a small chunk of the corner, but I'll need to find a thicker cover for these guys so they don't get eaten anymore!tl;dr great beds, dogs love them, but very flimsy cover. If you have chewers or hyper dogs, I suggest you get a thicker cover before leaving your dog alone with these!
