Congratulations on the new member. Your going to totally enjoy this baby boy. Yorkies.........what's not to love.
I'm not a bit surprised your Vet. put your baby on Science diet. It's one of the worst dog food you can get. The Vets. are only pushing it because they make a profit. Most Vets. are not trained in nutrition, and the ones that are, don't sell Science Diet!!

Buy Dr. Pitcairn's complete guide to NATURAL HEALTH FOR DOGS & CATS. It also has some nice recipes in it.
