Both my senior dogs love this new bed. This is the bed my oldest (13 year old) dog goes to the most now. I placed it alongside a round bed filled with stuffing (previous favorite), a square orthopedic bed, and a new orthopedic bed with bolsters. I thought she would like the orthopedic bed with bolsters better, but I think she likes this one because it's softer. Both dogs are 55 lbs. and fit in the 8x36x27 very comfortably. Sometimes Tippy likes to lie on it so half of her hangs over the edge.
