I need a good puppy treat recipe

[Gracie Belle]

As I was visiting my friend Stacey this past weekend I noticed that there were valentines on her counter for her daughter to give to her classmates at school. That gave me a sweet idea.  Gracie will also be in class (obedience class) on Valentines Day and I thought it would be a nice treat to give a valentine to her classmates as well.  I remember seeing before a recipe for dog treats.  I was wondering if any of you had some fairly easy and delicious recipes I could whip up for the other puppers in her class from Gracie? Thanks guys.
