Cranberry Oatmeal Dog Cookies

I made these with mini christmas cookie cutters as a party favor for the neighborhood dog moms and they were a hit! I used fresh cranberries (chopped small in food processor) instead of dried cranberries because it was impossible for me to find unsweetened dried cranberries. I would've had to order them in bulk online... They turned out great despite the cranberries not being dried. I would caution that this dough definitely needs to be rolled thin. The treats are VERY hard once they have had a chance to dry in the oven, and my small dog had a hard time crunching through some of the thicker ones. I also had a hard time just breaking them with my hands. It would be helpful to include instructions on melting the carob for those of us who aren't familiar with using it (do I need to make a double boiler? or can I just stick it in the microwave?)
