Preservatives are necessary to preserve the life of any kind of processed food, whether it’s canned or frozen food that humans eat or dog food. Some preservatives are toxic to dogs, however. When looking at dog treats, pet owners should avoid these shocking ingredients.
In addition to being used as a preservative, ethoxyquin is also used as a pesticide, and as a hardener in the production of synthetic rubber. The FDA has been investigating this preservative because it may be linked to liver and blood problems.
Butylated hydroxyanisole (BHA) and Butylated hydroxytoluene (BHT)
Both of these preservatives have been named suspicious cancer-causing agents by the World Health Organization. In addition, the State of California has identified BHA as a possible carcinogen.
This preservative is used to keep dog food moist. It’s also the key ingredient in newer automotive antifreeze brands. It’s been shown to be bad for some animals because it causes a life-threatening blood disease. Because of this, the FDA does not allow it to be used in cat food.
TBHQ (Tertiary Butylhydroquinone)
This fat preservative is used to increase the shelf life of dog food. It’s also used to make explosive compounds more stable, and to make varnishes, lacquers, and resins. It’s been found to cause pre-cancerous tumors in laboratory animals, and it can damage cell DNA.
These are just some of the shocking ingredients in dog treats – there are many others. When looking at dog treats for their dogs, pet owners should read the ingredient list carefully, and do their research to find out if the products in dog treats are safe.
