Unfortunately that just doesn't work with yorkie puppies..the theory that if they get hungry, they'll eat. When blood sugar drops from not eating, the body goes into a ketotonic state where it tells its self it's not hungry (how starvation diets work for a while..lol) and once you get to that point, they won't eat even if they should be hungry. Other breeds you can get away with being a stickler, and making them eat what you give them, they don't fall out in a matter of hours from sugar drops. My suggestion, Dick Van Pattens ROLLS...I haven't met a dog yet who wouldn't gobble them up. I put mine in the food processer in bulk, then put it in the freezer, and scoop out about 1/8 cup on everyone's dry food, throw in their supplements, stir it up, and VOILA..dinner is served.
So far, SO GOOD!

You can do a zip code look up to see where you can find it close to you, but if you have to order it, in the meantime, try the rolls you can get at Petsmart.
