Hi guy's i'm new to this site!
I rehomed a 9 year old male Yorkie in April 2014 and he is a rather awesome dude who I think was treated bad in his last home.

Anyway since I've had him i've noticed strange things about him that might just be how he was brought up, specially his mood changes, he has patches of being very depressed and doesn't eat for day's sometimes, when he is depressed it's a struggle to get him to even move and you can't force him because he will snap (he's a very bitey and snappy dog) and he tends to shake a lot too.

Yesterday morning he vomited and didn't eat anything all day or night, and today woke up to more vomit and he still hasn't eaten anything, he did have a few licks of water though, and again he is on the sofa today under his blanket and still refuses to move, i'm worried about him not eating and vomiting if anyone knows what may be wrong? if he doesn't get any better by tomorrow he will go to the vets but i was just wondering if anyone else has had similar problems.
