Teeth Treats are softer than the average dental treat, which means dogs have to chew through the entire treat; no more breaking off large chunks and gulping big pieces. This makes Teeth Treats safer and more effective at cleaning dogs' teeth. Plus, the patented shape helps dogs grip each Teeth Treat better, allowing them to bite off smaller pieces that can rub against their gums while they chew. The unique nubs also break off to rub against the gum line and prolong chewing. The longer a dog chews, the cleaner his teeth will get!
