This is by far the best bed I have ever bought for my dog from a durability stand point. My Boston Terrier absolutely loves it. However, I have had this bed for about 9 months and have always had problems with the zipper on the bupper portion of the cover. After the cover is washed according to the washing instructions the zipper will skip on the zipper links and not zip back together properly. It takes a lot of picking and working the zipper for it to zip back together correctly. I always dread having to put the bed back together after each wash. I have been in contact with West Paw and they seem to take the complaint seriously and are working with me on a possible replacement of the cover.
