Is the painkiller a pill? Because I was thinking and took my medicine and Guinness is a HUGE licker well I noticed that he was a calm calm calm puppy one night and after putting two and two together I think he might have licked some pill dust off my hand and being how small they are I can't help but wonder if the dust is just enough for them to get the effects hmmm
Now I know my painkillers that make forest animals visit me
is more of a capsle so that theory would not work.
