Charming Pet Absurd Burds were designed for the shaking movement dogs make when they play! With every shake of the toy, a unique quack sound is released making play time more exciting! The floppy construction allows your dog to shake the toy on their own to release the same sound or chomp on the toy to release another silly sound. Featuring K9 Tuff Guard Technology for added durability, your dog will go ABSURD over their new BURD buddy!
