I should have paid more attention to the material before purchasing. This product is a hard piece of plastic with sharp ends (the dinosaur tail). It scraped against my puppy's gums and would make him bleed all the time. Also, it was not very durable as the tail had warped within 5 minutes. Once I noticed this I threw it away before it caused more damage, or worse, fractures/broken teeth. Puppies need something a little bit softer to help massage their sore gums, not make them bleed. I've switched to kong products and toys using similar material, which works much better.
