If you do a search, you can find a lot of recipes already posted here. Since dogs are MUCH easier to please than people, almost anything you mix together and bake for a while will thrill them - I use rice flour, oatmeal, an egg, some peanut butter, chicken broth, grated carrot, sometimes some grated cheese... if you're a baker at all, it's easy to wing it! And I have no patience for the fancy things, like cookie cutters - the dogs don't care, so I press the whole batter onto cookie sheets, and when they're done, I cut or break them into pieces. If you like crunchy, baking at about 300 or 325 for a bit longer will allow the batter to dry out more and be crisper - 350, they'll be more cookie-like.
The worst I ever did was with liver. I boiled that stuff up and threw it into the blender to smooth it out. Unfortunately I didn't let the liver cool and when I hit the blend button the steam build up blew the top and most of the liver out of the blender and all over my kitchen. The dogs were in heaven. I, on the other hand, was cleaning liver off the ceiling, cabinets, nooks and crannies for ages it seems.
1 cup canned pumpkin or 5 bananas
¼ cup honey
¼ cup water
2 tablespoons canola oil
1 tsp vanilla
4 cups all purpose flour
1 tbspoon cinnamon
¼ tsp baking powder and baking soda
Preheat oven to 350
In a large bowl combine all ingredients knead dough until it holds together… transfer dough onto large floured cookie sheet ( split into two equal pieces) then shape each piece into a log flatten the logs so they are about 4 inches wide , with a fork poke holes into the dough. This dough does not rise or spread out so you can place each log about 4 inches apart. Bake at 350 for 35-40 minutes or until firm to touch. Remove from oven and let cool for 30 minutes. When cool cut into ¼ inch wide biscotti pieces. Turn oven down to 300 and put cookies back in the oven for 30 minutes longer or until COMPLETELY HARD.
Once cool place in air tight container .
You can play around with this recipe. I use Peanut butter and Banana. You can add Dried Cranberries and oatmeal to.. its very forgiving . you can use applesauce instead of oil. As long as the consistency is dough like its pretty fool proof. I find the pumpkin makes the dough very squishy so you may have to add more flour.
