Fat Balls / Weight Gain For Dogs

Why I Love This Recipe
I did not come up with these. They are from the rescue group I deal with.
These recipe's are for dogs that need to gain weight. Don't give as a regular treat otherwise you will end up with a chubby puppy
Ingredients You'll Need
1 lb hamburger,
1 package cream cheese,
1 dozen egg yolks,
