I absolutely love the crib mattress cover from Molly Mutt. The fabric is vibrant and sturdy. I appreciate that the zipper is designed to tuck in so my dogs can't chew it off. I had purchased dog beds in the past and my dogs both chewed them apart within the first hour of bringing them home. By purchasing this well-made cover, I am saving the mattress from filling a landfill, allowing my dogs to have the best quality bed orthopedically and the pet bed is indestructible. None of this would be possible without Molly Mutt. Try them, you and your pet will love their products!
