Liver Dog Treats (puppy crack)

I made these for my little helper now it is all he wants.

1 lb liver
1 1/2 cup unbleached flour
1 cup steel cut oats
1/2 cup water

Boil the liver in water until no longer pink about 10 minutes.
Grind the liver using the smallest plate you can.
add all ingredients in a large bowl and mix until combined. (I used my mixer for this.)
roll the dough to 1/4 inch thickness
use cookie cutters to cut cookies.
Bake at 250 f for about one hour until bone dry (no pun intended)
