While this item is well-made, the inside dimensions are very limited. The raised sides take up a lot of the circumference. The edge of the pillow fits partially under the sides leaving a useable area of about 7”x8” for your pet to lie down flat. I have a 5 pound Maltese who can’t lie comfortably. Also, the top cover does not stand up as shown in the picture. I do not recommend this product for a dog, unless perhaps a very tiny one.

I bought two of these for my cats. They fight over who gets to sleep in them. I have one cat who drags the bed around the house with him to make sure no one takes it from him. I’ve had them for a few years and they’ve held up wonderfully. Very easy to wash and dry. Highly recommended
