Q: Is Soy Protein safe in pet food?

Soy Protein is generally considered low-risk, but it is good to be aware of for dogs. Soy is one of the more common food allergens in dogs and contains phytoestrogens (isoflavones) that may affect hormone levels with long-term exposure. Dogs clear these compounds better than cats, but it's worth knowing about if your dog has sensitivities.
