How to make dog treats

I found this note by our front door a couple of weeks ago. It's from the two little girls that live next door. In case you can't read it, it says:

1. peanut butter
2. water
3. dog treats
4. microwave
golden retriever

A week later, they came by and gave Brian a cup of what appeared to be watery peanut butter and told him he just needed to add the dog treat to it and then give it to Charley. Too cute!
