Cool Gel❄ for Uncomfortable Dogs -  The Bowsers Oslo Ortho Bed is the best of both worlds for the dog that's slowing down: a scooped, easy-entry front design combined with Cool Gel❄ Memory Foam support. Beautiful, premium US fabrics are used for this Scandinavian-inspired orthopedic bed. When joints ache, cool application feels good. Don't let your older pup's achy joints keep them uncomfortable when they're trying to rest. Let the Cool Gel❄ Memory Foam provide cool relief to their geriatric and/or stiff joints.  The memory foam cushion insert is infused with Cool Gel❄ which helps regulate your pup's body temperature. If your thick-furred breed is feeling overheated, give them the Oslo experience to help them cool down!  Elegant two-tone US fabrics are used for a luxe European-style "pinched edge" design. Generous sizing maximizes your dog's (or cat's, if they're pushy) sleeping area.
