Give your dog - or dogs - the gift of squeaks with JW's? ISqueak? Bones. JW Dog ISqueak Bones are lightweight and bouncy and have our patented safe squeaker technology on the inside. The squeaker is designed to fall inside the toy instead of out to prevent choking should it become dislodged by your dog. Made from durable rubber, ISqueak Bones are great for moderate chewers and also work great for fetch!
