Has she been outside recently ??
I ask bc I took Roxy for a walk around my block on Sunday bc it was so nice outside. On Tuesday, she was *quiet* in the morning, she just lied in bed (usually, once she knows I am awake, she is bouncing all over the bed to get up). She turned on her back and I was rubbing her belling and I could hear some girgling noises. We got up and she refused her AM meal, only eating her favorite the apple bits. This is ODD, bc Roxy LOVES food, but she wouldn't eat. A little while later I found a huge apple vomit pile in my room. I left her home all day and when I got home at night she seemed better. I offered her dinner, and again, she refused to eat her food, only eating a few lettuce pieces. Within 1/2 she had such foul poop with mucus and blood, and then she vomited her lettuce. She is ok now, but she had to have picked up a *bug* or something on our walk
And something similar happened to 2 of my Mom's Yorkies a few weeks ago and she is in AZ...
IDK - I am so sorry
