* 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”, said Planet Paws.
* Rawhides have been repeatedly treated with chemical baths that includes a highly toxic recipe of sodium sulphide liming to strip away hair and fat attached to the hides. The outer layer of the hide becomes leather used for human items, while the inner layer is used for dog chews.
* Rawhides are painted with artificial dyes and flavors or even a coat of titanium oxide to make them look nice on pet shelves. The toxic confection of chemicals and preservatives make for slow, low-dose poisoning according to thebark.com.
* Rawhides, when tested, have been found to have lead, arsenic, mercury, chromium salts, formaldehyde, and other toxic chemicals. Glue of questionable nature is also used at times to hold the rawhide's shape and form, said Planet Paws.
Rawhides usually come with a printed warning as to how it could block a pet's esophagus or digestive tract leading to surgery or death. Planet Paws said this should already discourage dog owners from purchasing rawhides and feeding it to their dogs.
