Some years back, hubby and I got a Pembroke Welsh Corgi. He was just a puppy when he found something in the yard that he brought back into the house. I was sitting at the computer when I smelled something weird. I went over to see what he was chewing on, and it was the leftover remnant of a cigar. He had eaten a lot of it.
I expected him to get quite ill from it; but, he had no problems.
