Ugh I hate that, happened to Eko at petsmart a little pom barked at him while he was sitting down not even looking at it and the owner yelled at me.
And that was after I got multiple compliments by the staff on how well behaved Eko was.
Edit: I dread to think of what my new little APBT will be accused of, I've been walking her when no one is around specifically because of this.
