How can I fatten up my 1 year male Samoyed? I want to do it in a safely manner.?

Satin balls. Many people use these to put weight on show dogs. Google recipes for Satin Balls for dogs. They really work well for putting on weight, plus it gives the dog a really shiny coat. You can feed them as a meal or as a treat. Freeze in cupcake pans and then place in zip lock bags. Keep frozen and defrost as needed.
