"I have 2 puggles - and bought this bed when we adopted the second (he was 2 years old when we got him almost 6 months ago) dog named Coal. He weighs 45 pounds, and our smaller female puggle weighs 18 pounds, and both dogs can will curl up on the bed without a problem. Our girl Mylo does not have her own Cesar bed, and she tries to steal it from Coal all the time. When we first got Coal and were training him not to come in our bed at night, I would lay on the dog bed with him, and it is VERY comfortable. I weigh 170 pounds, am pregnant, and even I do not sink to the floor on this bed when I am on it with Coal. You do not need to get an insert to supplement the padding on this bed. The thing I was most impressed with was how well it holds up after putting it through the washer and dryer. Many products with microfleece are not as soft after this, and many products have padding that will get destroyed by the machines. The removable cover is THE BEST THING EVER, because both the fleece and the bolster come out looking perfect afterwards. I cannot say enough good things about this bed!"
