The largest dog beds for big and giant breeds are typically labeled XXL or Giant and are designed to support dogs 90 lb and up, like Great Danes, Mastiffs, Bernese Mountain Dogs, and large German Shepherds. In round styles, the most spacious options usually measure roughly 48–60 inches in diameter to let your dog sprawl or curl without hanging off the edge. Rectangular orthopedic beds for giants often range from about 54×36 inches up to 60×48 inches, giving ample room for side sleepers and seniors who need extra joint support.
To choose the right “largest” size for your dog, measure from nose to base of tail while your pup is fully stretched out, then add 6–12 inches for wiggle room and bolsters. Also consider thickness: deep, supportive cores (often 6–8 inches or multi-layer foam) help keep heavy dogs from bottoming out. Bolster height matters too—taller, structured bolsters create a secure nest while still leaving a wide, open sleep surface.
If you prefer a cozy, rounded silhouette for home comfort, look for oversized round beds with plush bolsters and durable, pet-safe fabrics that can stand up to daily lounging and frequent washes. For travel or room-to-room moves, a lighter but supportive construction can make life easier while still delivering the comfort large dogs crave.

XXL beds offer full-body support, reduce pressure on joints and hips, and provide enough space for natural sleep positions. They also minimize edge-hanging, improving rest and overall comfort.
With quality materials and regular care, an XXL bed can last 1–3 years or longer. Longevity depends on foam density, fabric durability, and how often the cover is cleaned.
Many bonded dogs will happily share, especially with an XXL or Giant size. Ensure the bed offers enough surface area and support so neither dog is crowded or sinks to the floor.
