Motivating dogs and puppies in a very distracting environment (like classes)
requires a high value reward. Here are some useful recipes (thank you Carol)
to help - Liver Cake, Gingerbread Men, Tuna Loaf
I make fish cake with a mix of 2/3 oats and 1/3 plain flour plus 2 eggs (whole); add a can of sardines and a can of mackerel, a carrot, some blueberries plus oxo stock water to mix all in the food processor.
Put into lined loaf tins and bake on 160 degrees for about an hour. Cool and slice, freeze for use later.
