Sorry, I slept too long and my brain is fuzzy. I thought you were talking about dog food. But I never heard about any dog food with initials. .......read a little further down - Embarrassing!!!!!! I have never yet worried or thought about feed dogs. I clean everything up after I finish a quilt and then I forget what I cleaned. Not necessary for me to know the ins and out, only when I have a problem. Then I go berserk!!!!! Have a good day. I am going to spend a beautiful day out on the deck with a glass of wine and my trusty Singer Instruction Book!!!!!! Maybe I will learn something. Edie
