Okay, I just looked up food allergy vs. food intolerance (in humans) and found the following article from the Mayo clinic:
https://www.mayoclinic.org/diseases-...y/faq-20058538
So a food allergy is an extreme reaction that can result in anaphylactic shock. A food intolerance is much milder (examples include lactose intolerance and celiac disease) and results in milder responses, such as diarrhea, irritable bowel syndrome, etc (which are still bad, in my opinion). Mayo clinic states that if you have a food intolerance, you *may* be able to eat small amounts of the offending food without trouble.
Still, it's a little dodgy for Fromm to answer a question about food allergy with a response about food intolerance. Their response to the question does hedge a little bit when they say "We have many customers who believe that their pet has an allergy to a certain ingredient, but they are surprised to find that their pet does quite well after switching to Fromm, even if the recipe they feed their pet contains the suspected allergen."
So Fromm's response is that basically some people think their dogs are allergic to a specific ingredient, but they don't know what they're talking about--it's most likely a food intolerance. That may be true, but if a vet tells me that my dog has a food allergy, and it really is a food allergy, then Fromm's response is dangerous. They need to rework that web page, because it's bad advice. Also, Fromm's reply to that question is that even if your dog has a food intolerance and not a true food allergy, try our food anyway because it probably doesn't have enough of the offending ingredient to make your dog sick. Sorry, I'm not buying it. If my dog has food intolerance to chicken, and the food contains chicken, even if it's further down on the list of ingredients, I'm not going to get that food. There are plenty of other dog food brands out there that don't contain chicken.
