I wouldn't only feed a Yorkie once a day. Feed the proper amount, but divide it up. Look on your puppy's kibble bag. It will tell you how much to feed. You could throw your Yorkie's sugar level off and end up with a very sick puppy if you only feed once a day. Also, milk is not a good idea and often times results in the runs. A pup doesn't need milk after being weened from his mom. Hope this helps a little.
