The cookies are very simple (like nearly everything I do!). I put two cups of flour in a bowl, added a bit of baking powder (maybe 1/2 tsp) and a couple of shakes of salt. Then I dumped in the cup of hot stock and stirred until it was a smooth dough. After rolling it out to about 1/8 inch thickness, I cut it into roughly equal pieces, put the pieces on a pan, and baked them. Usually, I try to take them out of the oven when the biscuits are pale brown, but this morning, I got distracted while they were in the oven.
Monty and Bree had knocked down a gate and escaped overnight. Bree loves to do this. She was born a mile away from here and she likes to go visit her family sometimes. She probably wanted to introduce them to her new friend. Anyway, I was baking dog cookies when I looked out the window to see that Monty had come home for his breakfast. I ran out to put him in the paddock, and overcooked the biscuits. (I'll have to go get Bree later, after she's had time for a nice visit.)
These dog cookies are a lot cheaper than the store-bought kind, and my dogs love them. You don't need a recipe. Use whatever broth you have (chicken giblets are great) and whatever kind of flour you have. The salt and baking powder are optional. Store them in a paper bag.
