I bought 2 of these as replacement for my previous  (different brand) that was 5 years old. I bought the model for 100# dogs. One is for a 80+# lab/pit the other is for a 20# pekingnese who would steal the biggest one if i bought seperate sizes lol! They already love them. Dolly mostly just plays with her toys on hers. Moose uses his as more of a trampoline playing with his toys. These beds are perfect for dogs that get hot easy as the mesh and raised bed allow great air movement. Cleaning is as easy as a water hose! Dries in minutes.
