Welcome to you, Sammy, and Sadie! I've found Yorkietalk very helpful in learning so much about the best care for Yorkies. For example, raisons and some forms of sugar substitutes (xylitol) can are highly toxic to dogs and just a small amount can kill a yorkie, make sure you read over the toxic list, the first year they will eat everything they can find. Check out the emergency help in the Library, so much good information!
