Just sharing this recipe, as it is a product of my imagination and desire to have happy dogs. So far so good:)
Rice– 2 cups (cooked)
Chcken livers (2-3) cooked
Green string beans (half a can) cooked
Carrots (half a big carrot) cooked
2 Eggs stir in slowly before you bake mix
Little parmesan cheese stir in
Cook mix well on tove first and stir together, pour in tray coated with oil (so it doesn’t stick to the bottom)
Bake at 375 until composition hardens but is not burned. It will continue to harden after you take it out of oven and it cools off.
Let cool and cut in cubes.
