Treat your dog to clean teeth and a happy smile with Ark Naturals Brushless Toothpaste dental chews! Every time your dog chews he does the cleaning for you; the unique texture helps reduce plaque and tartar and the ridges help clean along the gumline. They're the only 4-in-1 dental chews with a chewy toothpaste center that polishes, just like our own toothpaste. Daily chewing and aromatic spices freshen your dog's breath, but are recommended up to twice a day!
