Natural Colors Are Preferred
Bad dye jobs aren't limited to beauty mishaps. Steer clear of chews that are fake, day-glo colors or sterile bright white. Most likely these chews contain unnecessary dyes, as well as toxic chemicals such as arsenic, lead and mercury that have been used to treat the animal hide itself. Chews should look organic, like they came from an animal, not a factory. (Gross, right? But true.)
Which Chews Digest Best?
Chews should also break down easily in the digestive track. Part of the reason some folks get concerned about the safety of rawhide is that larger pieces can get lodged in your pet's stomach at any point of the gastrointestinal system. If pieces are small, then they will pass through your pet's system. Many pet owners decide they'll simply watch their pet while they enjoy their rawhide, to be sure the pieces going in...will be able to go down. A good general rule is to give your pet a bone (rawhide or otherwise) only when you'll be home. Don't throw one on the way out the door. For that purpose try a regular dog treat. Save bones for a time when you'll be able to supervise.
