Ex Input:
So life with a gluten allergy can sometimes seem unfair; however, once bisquick started making this product, things got a lot more equal. It tastes like Bisquick. It works like Bisquick. Hey, it is Bisquick. It just happens to be gluten-free. Perfect pancakes! Enough said.

I have three Newfoundlands so we go through a lot of food!  One of the dogs has had severe health issues and since we've switched from commercial kibble to home made food, he's thrived!  He gets regular blood tests to monitor the drugs he's on and they have been perfect since we started on Sojos!  It will not cure his issues, but he has more energy and he can't wait for meal time!  The other two are glowing with health as well!  All three dogs coats are shiny and they have tons of energy (for a Newf!)

My cat will NOT eat this food. I don't know why, but it was a waste of money. I was looking for something cheap so I guess you get what you pay for.
