I raise Shih tzu's and My wife and I have made many beds so my dogs do not have to lay on the tile floors in me Kennel. Some of them have chewed almost every bed we made, we even changed how we made but it did not work, they chewed then anyway!! These bed we purchased from you have held up! the only thing the have chewed were some of the corners and we purchased new one's from you and replaced them! so they are still intact!!! Great beds!
