Plastic Pencil

I accidentally burned at the end of a pencil covered with plastic, my room smells like I just lit a match. Is it okay if I did, and accidentally my dog sniffing the smell? Also, how long does it take for the smell to go away?

... You'll be ok! ... Open a window and turn on a fan and blow towards the open window!

It'll take a few days to a week until the smell out, even if you do not aerate. And if you feel very small, I think everything will be fine. But if it was a lot, id get him checked.
