Bully sticks, pig’s ears, cow hooves, marrow bones, rawhides and antlers. Sounds like a yummy smorgasbord for your dog, doesn’t it? I bet many of you use these treats to satisfy your dog’s chewing and keeping them occupied; but should you? Have you ever given deep thought to these animal “pieces parts” that we give to our pets??
First where do these things come from and why are they used as chew toys? I think it is obvious that these are all parts of animals that we eat. Not that we want to think about it but these are waste byproducts from the meat industry. Some entrepreneur decided this would be an easy way to make money so…. a new industry was born.
• Cow hooves and pigs ears are what the name implies.
• Marrow bones are from the long bones of cows and pigs.
• Rawhides are the skin of cows.
• Antlers come from either deer or elk.
• So what do you think bully sticks are? Think about this one. Give up? They are bull penises! Hmm.
There are some dangers with all of these items. All of these have the potential and can cause intestinal obstructions, but equally important are the dangers that come from the way these are processed. They are first soaked for hours in a caustic lye solution to digest the undesirables off the skin and then to remove the lye the skin is then soaked in bleach solution. Sounds yummy. Many of the rawhides come from China where they have been known to use arsenic compounds to preserve them.
There is no regulation of rawhides or pigs ears. You really have no idea where these come from.
Marrow bones and antlers cause many broken teeth. A good rule of thumb is if you don’t want me to hit you in the kneecap with it, your dog should not be chewing on it. I can not tell you how many expensive extractions are the result of dogs chewing bones.
Another concern of mine is the potential introduction and spread of disease to naive areas. Many of the elk antlers come from Wyoming where the elk migrate and drop their antlers each year. These are collected in Jackson Hole, Wyoming, by Boy Scouts who sell them to support their troop. Many are used to make decorative pieces but others end up as chew toys. Wyoming has a devastating disease call Chronic Wasting Disease and is caused by a small protein subpart called a prion. Prions have the potential to be in antlers and other body parts and thus may be introduced into deer populations in other parts of the country. Much like the devastating Ash Borror that was introduced into my state of Ohio in firewood brought in from Michigan, the infestation is quickly depleting the Ash trees in the state. .
My biggest concern though with all these chew toys is the potential for passing harmful bacteria to your pet and YOU. There have been many cases of Salmonella and E. Coli contaminations directly linked to rawhides, pig’s ears and other animal product toys. The FDA has published an advisory warning of this risk and urges those who come in contact with them to wash their hands thoroughly.
Sorry for the disgusting facts in this blog, but hopefully I have educated you, so you can pick the safest products for your beloved pet.
