An underweight dog is at risk for additional health issues because he is not getting enough food to fuel his body appropriately. Dogs lose weight after illness, or because they were not fed properly. It is essential to feed extra calories and aid him in reaching a healthy weight as quickly as possible.
Place 5 pounds of ground beef in a large container. Choose the least expensive type of ground beef that the store offers in order to get the highest fat content possible.
Crack 5 large eggs and pour them into the ground beef. Add 6 cups of wholegrain flake cereal. Mix this together with your hands. It does not have to be completely mixed, just partially to make adding the remaining ingredients easier.
Pour in a 7 cups of uncooked, unflavored oatmeal. Use the slow-cooking variety rather than instant. Add 2 cups of wheat germ. Mix everything together with your hands.
Pour in 5 packs of unflavored gelatin, 2/3-cup of vegetable oil and 2/3-cup of unsulphured molasses. Mix all ingredients together thoroughly and form into balls about 1 inch around. Serve several of these balls with regular dog food at each feeding for several days. Remaining balls can be frozen for later use.
