welcome to yt and congrats on your new edition to the family....
yes you want to use a harness for everything instead of a collar. most just use a collar for the dog tags. the feedings .....not sure fatty...foods dont sit well with yorkies..and theyre bellies can be very sensitive but the diet ur giving sounds good but are you also giving vitamin supplements? that might be needed for the full nutrition. i feed my green peppers, carrots, and green beans for snacks. toxic to yorkies are grapes, raisins, onions, and garlic top of the list anyway... not sure about the chicken bones as that is something ive never done.
