I’m wondering if you can please advise?
Are Soy products OK in our dogs’ diet? I’ve done some research on it, and it’s all over the map whether dogs should or shouldn’t get it. For the most part, it appears Soy is in many types of dog food, so it confuses me why some sites say your shouldn’t give it to dogs, and others are promoting it? Just trying to get some clarification. Thanks, Glen G.
Soy proteins are excellent quality proteins for people but in regular pet food… not so much.
It’s used because it’s cheap.
Soy beans contain anti-nutritional factors (e.g., anti-trypsin) that stop protein digestion and proper absorption of nutrients.
They also contain non-digestible carbohydrates (sugars) that are likely to ferment in the colon and produce gas as well as other digestive disturbances.
If the soy is treated with enzymes then it becomes very nutritious for humans (tofu) and for pets with allergies, but only if treated this way.
In the enzyme digested form, soy is a great protein.
The soy enzyme hydrolysate is more than 96% digestible, which is similar to casein (whey) and egg and is actually more digestible than high-quality animal proteins like red meat.
In human and animal nutrition, soy hydrolysate has become very useful.
The quality of this protein source is such that it is used as milk protein substitute for allergic infants and in protein supplements for athletes or recovering patients.
In human medicine, soy hydrolysate-based diets are used to prevent the development of inflamed intestines in patients undergoing radiation and chemotherapy.
In regular dog foods it’s not the enzyme digested soy that’s used.
So your pet will probably not get much nutrition out of it.
More likely they’ll just clear the room.
All the best,
