My babies deserve to be comfortable when they're not on my lap or sitting beside me. My pug and puggle love this bed! It feels very comfortable with the memory foam. Thank goodness that my girls are house broken so I won't have to worry about the waterproof features. It's the perfect size for one or even both of the girls, each weighing around 18-20 pounds each. I have caught them lying side by side on it. When opening the shipping box and the plastic on the bed, it relaxed to about 4-5 inches and I am guessing about 36" in length. Overall, my babies, not me, love it and that's what counts.
