K&H Pet Products Self-Warming Lounge Sleeper Large Gray 32" x 40" x 10"

I was looking for a self warming bed for my two tiny pups (7 & 6 lbs.) to share, and expected this bed to be perfect for them. Ordered the 30”x20” size. I have several products from this brand that I have been quite happy with so it seemed to be a no brainer that this bed would be perfect for what I needed. Unfortunately it was not. The bed is so poofy that my lil pups ended up around the edges of it, falling between the pillow part and the sides of the bed. Laying in the gaps, so to speak. Not so comfy since there is only a piece of fabric between them and the floor at that point. I stuffed small dog blankets in the gap between the cushion pillow and the sides to eliminate the gap, but that kinda erases the bumper feature of the bed. We're making due with it for now, but I've had to order something else to replace it. I'll pass this bed along to someone with a larger pup that won't fall in the gaps along the sides. If the attached pillow section and the sides were actually attached to each other, instead of both being attached to the bottom, there would not be a big gap around the edges. The quality of this bed seems great though. The upholstered outside is beautiful, and the inside is super soft. Great bed…for heavier pups.
