The Liker balls are made out of a unique proprietary material (not rubber) that is safe, nontoxic, scentless, lightweight, durable, strong, and does not damage or wear down your dog’s teeth and gums. The resilient material actually lets your dog’s teeth sink deep inside it, without the ball losing its shape and strength.
Dogs love the gentle squishy feeling when they chomp down on the Liker ball and we've found this toy quickly becomes a favourite. The Liker ball is not intended to be used as an unsupervised chew toy, but we experienced no problems with allowing dogs to chomp on the Likers as they retrieved them and also as a reward at the end of play or training time. We just took the Liker away when the interactive session was over.
If you and your dog enjoy water games, the Liker balls also float. They float high on the water so your dog can grab them without ingesting a lot of water.
