One of the best treats for training I have found!
Below is the recipe that was given to me by a lady at the dog training class Obi and I attend.
Recipe is: 450g of liver, pigs, ox, lambs or chicken. Blend with 3 eggs, and same amount of water (so if the eggs are 150mls, add 150mls water) you can use milk but due to intolerances probably best to use water. Once blended, add in 1llb of self raising flour. If grain intolerant the use alternative grain free flour. Pour mixture in baking trays, fairly thinly spread and bake for about 25mins gas mark 4. Leave to cool and cut into small pieces, can be frozen.
