My two beagles love these to curl up in together or separately. I originally purchased a medium because the size worked with a different brand, but these run a little smaller so I got a large. The two curl up in the big one and each separately go into the medium.
the colors are nice a bright...something I love about Westpaw.
I havent had for very long to comment on durability...My dogs will drag beds around the house so I will let you know.
