Many companies design doggie playthings specifically for dental health like flavors spearmint and/or peppermint to entice dogs to interact, also they incorporate bumps, holes, grooves and woven cotton rope that act as a floss. The different textures and grip areas make it easy for dogs to hold a toy in their paws, encouraging them to play longer. When seeking a dental toy, avoid products containing harmful dyes, BPA and other chemical components. When ingredients are not listed on the label, contact the company for more information. Better safe than sorry! Keep in mind that the FDA doesn't regulate dog toys, which means it's up to you to ensure a product is safe before tossing it to your pooch.
