Your dog has specific needs, and maintaining good oral health contributes positively to his overall well-being. That's why the experts at Purina® developed Purina® Dentalife®, a dental chew that is scientifically proven to help scrub even those hard-to-reach back teeth, that are the most vulnerable to plaque and tartar build up. Our dental chews are designed for daily usage, and every day chewing means more time cleaning.
