The Binkie helps teach your puppy appropriate chewing behaviour. It is made from the unique kong classic rubber. Extra durable and tough whilst also softer on a puppies mouth. It fufills instinctual needs to chew whilst easing aching teeth & gums. You can entice your puppy even further by placing a treat (KONG Puppy Easy Treat/ Kong puppy snacks) in the centre to keep them happily playing for hours.
