Some people in my obedience class last night brought up a question about cigarrete butts. Several had heard that feeding your puppy/dog or letting them eat cigarrete butts was a cure for some kind of worm?? I had never heard this and would never feed or let a dog eat them, but they asked the question so I told them I would do some asking around. Of course, regardless of whether it is true or not, I think there are much safer ways to get rid of worms in a dog than this and told them so. Just curious as to what others have heard and what the truth is on this possible myth?
