Brand new 22”x35” Deluxe memory foam dog mattress for hip displasia

Got this fab mattress from Amazon last week. It is everything they said in the ad, but… Pushed the wrong button. Got the wrong size. My dog loved it for 5 minutes but her legs kept falling off when she relaxed. It was fairly entertaining, but not worth keeping a $100 mattress for. My mistake, your pup’s gain.
