Rawhide the most dangerous chew!!! A rawhide stick is not the by-product of the beef industry nor is it made of dehydrated meat. Rather, rawhide is the by-product of the “Leather Industry”, so theoretically it is a leather chew. Normally, cattle hides are shipped from slaughterhouses to tanneries for processing. These hides are then treated with a chemical bath to help “preserve” the product during transport to help prevent spoilage. Once at the tannery: the hides are soaked and treated with either an ash-lye solution or a highly toxic recipe of sodium sulphide liming. Hides are washed and whitened using a solution of hydrogen peroxide and/or bleach; this will also help remove the smell of the rotten or putrid leather. Basted, smoked, and decoratively tinted products might be any color (or odor) underneath the coating of (often artificial) dyes and flavors. They can even be painted with a coating of titanium oxide to make them appear white and pretty on the pet shop shelves. When tested: Lead, Arsenic, Mercury, Chromium salts, Formaldehyde and other toxic chemicals have been detected in rawhides. So it’s safe to say that any sort of glues can be used as well! Check out the fine print warning that’s attached with some of these rawhides: Choking or blockages. If your dog swallows large pieces of rawhide, the rawhide can get stuck in the esophagus or other parts of the digestive tract. Sometimes, abdominal surgery is needed to remove them from the stomach or intestines. If it isn’t resolved, a blockage can lead to death. OUR ADVICE TO YOU IS NEVER TO FEED RAW HIDE!!
