I tried using chicken liver in my treats once, they didn't seem to do as well as say, beef liver. I usually mix the 'meat', (whatever it is or salmon), with something like organic oat flour and minced garlic, you want it rather 'pasty' feeling. Spray or use a coated meatloaf pan, and I normally weigh out a pound of mixture to a pan..I usually bake at 350 around 30 minutes,,cut up into tiny bits.
