Ditto. Ditto. I used fat scraps, chicken fat, oils and lard as well. Like FP says, the dog has to be doing the work to offset those calories. The dog burns fat at a better rate than we do but the principle is still the same. If a dog eats XXXX amount of calories and only burns XX there is weight gain. The key is matching the amount of work to the amount of food and then adjusting as things move along. EWO
