[Ponyup]

My dog has been vomiting since 5:30 this morning. About 1 every hour or so. The last time he threw up anything was at 9:30 & it was the pepto bismol I gave him. Since then he has dry heaves twice. He refused to drink or eat anything. He tries to lay & sleep but get these shivers. I just gave him a bit of karo syrup on my finger. The shakes are what are really concerning me & this is the first time he's ever refused food. I tried given him his normal food & rice & chicken, but he just turns his nose up. I would rush him to my vet, but i'm 5 hours away at my in-laws. We are planning on going home today, but not until 4. I'm just beside myself with worry. Any help would be appreciated. He may have eaten any number of things yesterday. Everyone was feeding him & wouldn't listen to me what i said he's had enough. He may have ingested some onion, but i don't see any yellowing of his eyes or gums & he doesn't seem to have a fever & his eyes are bright just sad. He may also been exposed to some poisettia milk. I will anxiously await any help so if you have questions just ask.
