Sounds like a blockage in the stomach or intestines to me - like he ate something he can't digest - part of a toy or any number of things.
If it is still going on tomorrow, get him to the vet and they can try to get whatever it is out. I have seem Yorkies swallow yarn, arms of toys, crayons, etc. If the ob ject doesn't pass, it can cause major problems. The symptoms you describe are spot on with my experience. |
