1. How is it made? Rawhide is made for commercial use from bull, cow and horsehides obtained from slaughterhouses as a byproduct of the meat industry. The flesh side is scraped clean of all remaining meat, membrane, fat, etc. Traditionally this is done by hand, using a drawknife and scraper. Modern day tanneries use a form of a band saw to speed the process up and make a nice clean piece of leather. Commercial manufacturers of rawhide products have machinery to do this. Once the flesh side is cleaned, the hair must be removed. There are two traditional ways of doing this. One is to “dry scrape” by hand. This is extremely time consuming, not to mention the amount of good ol’ fashioned elbow grease! Commercial makers of rawhide do not use this method.
The other method is to soak the fleshed hide in either an Ash-Lye solution or a Lime solution. The Ash-Lye involves covering or soaking the hide in a mixture of wood ash and water, which creates Lye. The hide soaks for approximately. 3 days in the Lye solution, then as much of the hair as possible is scraped off. The process is repeated until all hair is removed.
The Lime solution is the quickest and most often utilized by manufacturers. This utilizes ordinary builders powdered (hydrated) Lime. The hide soaks for 1-3 days and the hair is scraped off. This process is highly caustic but the most efficient for mass production.
To remove all traces of the Lime solution and to sanitize the rawhide product, commercial makers then rinse the hides in a bleach solution before creating whatever shape is to be used. The bone and other shapes used to attract you and your pet are created while the hide is still wet. The “treats” are then either dried or sent for “smoking” to further entice the unsuspecting owner and pet. A processed rawhide can shrink up to half its original size when dried.
If the chemicals used to make these “treats” haven’t convinced you to stop, please consider this:
When rawhide is again wetted, usually when your pet salivates over this chew you have provided, it will slowly regain its original size. When your pet tears off and swallows a piece, that piece then has the potential to swell inside your dog’s stomach. Your dog’s gastric juices WILL NOT break down the rawhide. Once swollen, the piece then has the potential to cause anything from mild to severe gastric upset, to death.
Don’t believe me?
Take the rawhide challenge. Cut varying sizes from different rawhide products and set them in a bowl of water to soak before going to bed. In the morning you will see the sizes that they have grown to. They will vary, but the increase should be noticeable.
Here's one more blip that was written by a vet:
Hidden Dangers: Dr. John Wedeking, an Iowa veterinarian, remembers hearing about rawhide in the news. “Reports of arsenic contamination popped up in papers once,” he says, but adds that it came from another country. Since rawhide is not regulated in any way, it could happen again. These foreign hides may also contain other detrimental things such as antibiotics, lead, or insecticides that could adversely affect the health of your dog.
Wedeking adds that dogs can easily choke on it when the original large rawhide object is chewed down to a smaller piece. “Choking is a hazard, and rawhide can cause gastric irritation when dogs chew on it often,” he says. Wedeking adds that gastric irritation can also cause vomiting and extreme discomfort in dogs.
