Orthopedic dog beds reduce stress and pressure on joints. Dogs who are elderly; have arthritis, have hip dysplasia, and dogs that weigh in excess of 75 lbs (i.e., Great Danes, Labrador Retrievers, Golden Retrievers, German Shepherds, Rottweilers, Mastiffs, Boxers, Doberman Pinschers, etc) benefit from orthopedic dog beds. Our BioMedic orthopedic memory foam beds are available in a 4" and 6". They are guaranteed by the manufacturer for the life of your pet to never sag, flatten out, or get lumpy. The fabrics are easy to clean and dig resistant. Waterproof fabrics are available. Heated dog beds provide additional orthopedic comfort.
