You can also fill with chicken, beef, or turkey broth and freeze. Makes your dog work for the treats, keeping him busy while you are at work. Unlike cheaper imitations, these toys have holes at both ends to keep a dog's tongue from getting stuck. Makes your dog work for the treats, keeping him busy while you are at work. Beware of knockoffs, others do not have the tough rubber, and can be chewed up. The specially designed rubber is splinter-proof and puncture-resistant. The combination of the rubber and the shape leads to a toy that bounces in an erratic fashion for fun outdoors.
This version is the same rubber used in the Extreme Kongs, but in a special blue color that is designed to be seen on x-ray films in the unlikely event that your dog swallows chunks. The rubber in this toy is extremely tough and dense.
