Welcome to Yorkietalk. I'm sure you'll get a lot of great information from experienced people - I didn't get my pups until they were 12 weeks old so don't have any suggestions regarding shampoo. As for food I feed my Darwin and Mabel Go! Natural as it has no fillers or corn. Orijen is another brand that is also really great. The food is a lot more expensive than Puppy Chow or some other store brand but Yorkies don't eat too much and it's definitely worth feeding a premium food. All I can offer is to make sure you get a harness instead of a collar as Yorkies have delicate tracheas and can be injured easily. I am using a ferret harness on my 17 week old Mabel as I couldn't find a dog harness that would fit her. Good luck and take care your little baby!
