Does Your Dogs Store Bought Food Contain this Toxic Ingredient?

You probably answered an immediate “no” to this question, possibly with laughter and scoffing in your voice – who would do that?? But, if you are feeding low-quality food or treats, chances are, you are feeding your dog a compound used to make antifreeze, propylene glycol. Well, if it’s in my dog’s food, it must be safe right?

Let’s talk about what it is first, before we answer that question

Propylene glycol is a synthetic substance that is used in all sort of things – from antifreeze to food. It has many other names including: 1,2-dihydroxypropane, 1,2-propanediol, methyl glycol, and trimethyl glycol. It is a petroleum-based product made of two alcohol groups. It is odorless, but has a faintly sweet taste, which is why animals like it. The Agency of Toxic Substance & Disease Registry explains that it is a liquid substance that absorbs water. It is used for a variety of things:

* To make polyester compounds.

* As a base of deicing solutions (which, by the way, are poisonous to pets!)

* Used by the chemical, food and pharmaceutical industries as an antifreeze when “leakage might lead to contact with food.”

* To Absorb water and maintain moisture in medicines and cosmetics.

* As a solvent for paint and plastic industries.

* To create artificial smoke or fog.

For food, it’s used to absorb water, maintain moisture, and as a solvent for food colors and flavors.

Sounds like something that should be ingested, doesn’t it?

Yet, the American Food & Drug Administration (FDA) classifies it as “generally safe” for consumption…for people as well as dogs. HOWEVER IT IS NOT DEEMED SAFE FOR CATS!

Interesting, yes?

Blue Buffalo issued a recall a few years ago on one of their cat foods because propylene glycol was found in them. In cats, propylene glycol is known to cause Heinz Body formation in the red blood cells. It reduces the red blood cells survival time, renders red blood cells more susceptible to oxidative damage and has other adverse effects in cats.

In dog food, propylene glycol is used to absorb water, but also as a sweetener because it’s cheap and readily available. Dogs love sweet – they have a similar palate to ours – and so that is why many brands use some type of sweetener, such as sugar, sucrose or propylene glycol, in their foods. It makes the food more palatable, masking the lower quality ingredients they use.

So it must be safe for dogs then, right?

There are a few problems with that assumption and a lot has to do with verbiage. The FDA says it’s generally safe…in low concentrations. Fine, you may eat junk food once in a while that contains propylene glycol and it probably won’t affect you. But your dog eats the same food every day. This means your dog is getting that synthetic, un-natural substance used in many unsafe products, every day.

The bottom line is – natural is best when it comes to your dog’s food. That’s why you won’t find propylene glycol in any Stay Loyal line. The health, safety, and wellbeing of your best friend is our top priority.

  2. Hi I use your product but my dog likes a bit of wet food mixed in. Can you recommend any? I have used a grain free one but that doesn’t neccasarly mean it’s safe. I think my dog like variety in her food. I have given her chicken necks before. She won’t touch a meat bone for some reason. She is a American / English Staffy.

    1. Hi Trudy, sorry I’m not up to date on canned foods. A grain free one does sound good. As for your Staffy, I can’t help to think you may be overfeeding if she is fussy. Try decreasing her portions and see how she goes. Check her condition/weight and adjust.

  3. I have a 14 year old Abissynian cat Zane and 2 dogs my 18 month old Cocker Spaniel Tara and Tinka who is 7 years old this year. She’s a cross between Pomeranian xTerrier.
    I feed my cat Whiskas both dry and can food. My dogs have boiled chicken cooked meat and dry food daily from the supermarket. I want to keep them healthy please advise.

    1. Hi Chrissy. Most supermarket pet foods are heavy on grains and are not that suitable for dogs and less so for cats since they are totally carnivorous. We recommend feeding a premium grain-free dog food and raw meaty bones twice a week for dogs. I don’t know too much about cats but know they need a lot meat and little to no vegetable matter.

  4. On your chart Iwould like to see what companies test on animals, I have read some terrible stories and would like to avoid any companies that use this practice. It is a very hot topic amongst dog lovers at present. How do you test your food and ingredients
