I recently bought an extra large Nature Nap from a West Paw retailer. It has been one of the best purchases that I have ever made for my friend, Gus (a 13 year old standard poodle.) The Nature Nap keeps him warm, comfortable and happy. Using it mostly in the evenings, Gus barely wants to move from it when it's time to go upstairs to bed. I am happy to have come upon the West Paw brand and have already recommended it to another larger retailer in the Boston area.
