forcing it onto them or anyone is abusive but some really seem to like and will seek it out. i had a german shepard that hated the smoke but would eat it every time a baggie or whatever container got left out. that little brown dog in the pic of me somewhere around here is a part-time smoke hound. he'll come around and jump on the lap of whomever has the bowl/joint and stick his snout up to the mouth and wait for an exhale or 2 before running off...but not all the time. and he hates it when it's forced on him...so i've always just let them decide.
