Could I have poisoned theself by using the gas fireplace with the flue closed

fireplacegas

Ive been using my vented gas fireplace for a couple weeks not knowing the flue was closed. How dangerous is this. I have myself & 3 dogs that were in my family room with me where the fireplace was burning. I'm worried I've poisoned my poor babies.

If they are not dead, and you are not dead, none of you got poisoned enough to matter. Just don't do that again.

Buy a carbon monoxide detector (or two, or three), and put a note on the fireplace reminding you to open the flue.
