I cannot believe the enormous stupidity of dog owners who buy those horrible doggie dental chews they advertise of TV. Get your dog a good old butcher's bone which will make your canine's teeth white & healthy. Don't buy these horrible, additive-ridden products. They are every bit as bad as the beef or chicken jerky they sell that's made in China. Or the dog food you buy with ANY ash content. If you love your pet, don't infect him or her with chemicals. Same goes for cat food. No wonder vets are so rich from the effects of these harmful substances. —Sometimes the Old Ways Are the Best Ways
