1/3 cup vegetable, avocado, or grapeseed oil (NOT Canola oil)
1 pound raw beef liver
+/- 2 cups flour (white, oat, rye, wheat, you can experiment with it)
Beat eggs a few seconds in blender. Add oil and mix. Using scissors, cut liver into small pieces and add to egg/oil mixture; puree. Pour mixture into bowl. Slowly add flour while stirring. You want the consistency of thick brownie batter -- not runny, but not like cookie dough either. Depending on your flour, humidity, elevation, etc., adjust flour as necessary. Add fresh minced or powdered garlic 'to taste', about a tablespoon.
Pour batter into non-stick or lightly greased jelly roll pan. (I use an 11x16 pan.) The thickness of your treats and the baking time will vary depending on the size of the pan you use.
Bake for about 10-15 minutes in 425 degree oven, or until the top of the 'cake' is dry and outer edges are browning. Remove from the oven. Cool 5 minutes.
Score with a sharp knife into 1/2" x 1/2" pieces. Remove the pieces from the pan with a spatula. Divide the treats between the baking pan and an additional baking pan or cookie sheet, and spread them out evenly.
TURN OFF THE OVEN, and return the two pans of treats to the oven and let them dry for about 30 minutes. Keep in airtight/watertight container in the refrigerator or freezer. (You can portion out each recipe, placing a daily supply into ziplock baggies; store in the freezer to use as needed.)
Makes about 350 treats. I make about one batch a week, and use them in both tracking and obedience for three GSDs. NOTES: I use an old Oster blender, and it works fine. You could also use a Cuisinart or other food processor/blender. I recommend that you cut up the raw liver into small pieces before feeding it into your blender to avoid blowing the motor. I've experimented with different flours (try ground rye flour for a heavier bait) and with chicken and calf liver. You get a little different result with each combination, and baking times may vary.
For example, I have used chicken liver with white flour, and added powdered spirulina to make a green bait. This works well as a camouflaged bait for tracking in green grass -- the crows and seagulls can't see it.
2 cups oats
2 cups shredded wheat
1 cup cooked liver [cut up after cooking, very small]
½ cup oil
4 large eggs.
Mix everything together to combine well. Cook 350ºF until browned. The liver looks like chocolate chips, so beware your human kids [or hubby] don't get into them
Another liver treat my dogs like is very simple.
Boil liver Slice finely. Place on baking tray Sprinkle with oil and bake until dried out. I store mine in the refrigerator.
