My dog just loves snuff. I can pour a pinch on the back of my hand and she’ll coming running up the couch to try to get me to give it to her… She doesn’t sniff it though, she licks it! Guess she won’t have any problems with worms… Here’s a pic of her begging for some… 
Lol I’ve never heard of dog’s wanting snuff before. There’s one in my local as soon as she sees me having a pinch or at least smells it runs a mile lol.
One of my cats ate some redman once. Not the same excately but still funny.
I have to attest to the power of nicotine addiction in dogs. Years ago I had a dog that would clean up every last cigarette butt it could find. The more she ate the more hyper and determined she would become to find more. Pulling on the leash and yelling at her didn’t help, she would scoop them up out of the grass and swallow them before you could react. There was no stopping her.
I was over at one of my friends houses last night, his dog did keep trying to eat my though I think it was because it thinks anything you pull out of your pocket most be treats.
hahaha mine takes a sniff and starts sneezin and snezzin hahaha but she keeps comin back for more.
