Do you know what’s in your dog’s favorite treats? With Mercola Healthy Pets you’ll know what isn’t in its line of USDA-inspected products – chemicals and preservatives.

This line of healthy pet treats is an offshoot of www.Mercola.com, a top-ranked natural health Web site. At the moment, the line is comprised of Beef and Bison Bites, Dental Bone, and the Clever K-9 Treat-Release Dog Toy.

Beef and Bison Bites ($20) is made from USDA-inspected, range-free beef and bison liver. They’re high in protein but contain no fillers or grains.

Your pooch needs one serving a day of Dental Bone ($20, small; $27 large). Made of USDA-certified digestible brown rice and packed with calcium and iron, this treat provide “natural abrasions” to clean teeth and promote fresh breath.

Clever K-9 Treat-Release (Regularly $20-23, but currently on sale for $15-17) gives your pet a lot to do. Small openings at either end of the toy allow you to store treats and kibble that are released as it is rolled and tossed during play.
