When it comes to Brushless Toothpaste Extreme Clean, you don't have to give them every day to see results. These once-a-week, longer-lasting chews are also longer in shape with deep ridges. This makes them great for more abrasively scraping plaque and tartar from hard-to-reach places since your pup can "hold" the chew. A more robust active ingredient toothpaste center and a higher dose of natural breath fresheners than Ark Naturals original Brushless Toothpaste chews also means more polishing and freshening action for your pup! Your pet's teeth will never be cleaner after adding these chews to your original Brushless Toothpaste or Protection+ regimen to keep them "Healthy from Tooth to Tail."
