Over the last decade, there has been an explosion of patents for flavored rawhide hitting the market, from bubble gum to hickory. And that’s not all, other poisonous residues that may show up in rawhide include lead, arsenic, mercury and formaldehyde. They may even be coated with titanium oxide to make them appear whiter. In the post-tannery stage, hides are washed and whitened using a solution of hydrogen peroxide to get rid of the rotten stench. Superfund sites.Īlong the way, various chemicals are used to slow down the rate of decay of the animal skin. A standard practice is to procure rawhide in the “split lime state” as byproducts from leather tanneries, facilities that top the list of U.S. Removing the hair from hides often involves a highly toxic recipe: sodium sulfide liming. The top grain is generally tanned and made into leather products, while the inner portion, in its “raw” state, goes to the dogs. Producing rawhide begins with splitting an animal hide, usually from cattle. While chews made from rawhide, bone, or other animal parts are consumable and are therefore considered “food” under FDA law, as long as the label contains no reference to nutritional value (such as “high protein”), the agency advises that manufacturers “may not have to follow the AAFCO pet food regulations.” If rawhide manufacturers were held to the same standards as drug makers, they’d be forced to add an equally long list of warnings to their labels: Rawhides may cause stomach torsion, choking, vomiting, diarrhea, and salmonella poisoning. But the closer you look at how rawhides are produced and the risks associated with them, the more you may want to wean your pup off this dubious byproduct. Your dog would like to convince you that rawhide is primal therapy for their carnivorous soul. It’s the equivalent of that marshmallow-filled cereal made with real oats that kids howl for all the way down the breakfast aisle. Promoted as an “all-natural” treat, rawhides keep dogs entertained, perhaps even more so when in its many basted, twisted, even brightly colored mutations. Among the piles of dog toys, the knuckle and femur bones, one pet store mainstay is the bins where the rawhide is cached. If you have a pup that loves to chew, you’ve probably combed the pet aisles looking for enticing substitutes for your laptop cord and chair leg.
