I run a business called The Exquisite Paw Club (sitting, walking, etc). One of my client's told me her dog cannot have many treats due to his allergy to protein. I felt bad for him because she has another dog who can have treats in normal quantity. So, I decided to make a recipe of my own using healthy food. My own dog, Iris, loves them, even though she isn't on a protein restriction. Note: Dough may be sticky. Still bakes fine. If sticky, roll with wet hands. Cookies will have less than a gram of protein. If worried or want to alter, check for protein content of what you use. Rice flour has the lowest protein when compared to wheat or all-purpose flour at 2 grams per 1/4Cup.
