Gucci is such a Hoover! Why bother sweeping? He'll just eat everything off the floor for you
Missy has tummy upset right now too. She's not vomiting but has diarhea (mucousy). I'm waiting for her next bowel movement to see if she has to go to the vet today. Anyways, point being...yes, I think these Yorkies get tummy upset easily. Missy didn't even get into anything that I'm aware of, and she's having troubles. It's really worrysome hey?
I hope your little Gucci-man gets well soon. I would think the "bland diet" of chicken and rice would be good for him right now. It is what my vet suggested for Missy.
Good Luck!
