Home-made Waterproof Customizable 40"x28"x4" Memory Foam Dog Bed This dog bed has a net weight of at least 12 lbs. We use high density of 4-lb memory foam for this dog bed making it difficult to be flatten out. There are many dog bed products from other sellers that use lower density (3-lb or less) and lower grade of memory foam that will sink in easily or degrade after a period of use. Thus, their dog beds are mostly half the weight of ours. Each dog bed comes with one durable water-resist external cover and one fully waterproof internal cover. The covers are easy to remove, clean, wash and dry. They are sealed with Velcro fastener instead of unreliable conventional zipper that are easy to break after a few months of use. This dog bed gives great comfort to healthy dog as well as providing therapeutic benefits and supports to injured (recovering from surgery, back pain, arthritis and other injuries) dogs and also dogs with incontinent problems. This is a Home-made waterproof dog bed that can support up to 100 lbs dog. Dog in picture weights about 65 lbs. This dog bed is customize-able so to fit into your dog crate or kennel. Please contact me to customize (further cut-down/trimming from the current size) the dog bed size to your desire size to see if the custom bed is feasible or not. Custom fee is applicable. SPECIAL OFFER for a limited time - We will add an extra external cover when you place 2 identical size dog beds in your order.
