In all honesty, animal rights wackos are a major pain in the butt.
I'm always worried that when we have a dog at the shop in bad shape, forwhatever reason, that an animal rights wackadoodle will call the cops for "animal cruelty".
I usually don't talk to people when I walk dogs, but there are a few that, if someone stops and shows intrest, I always stop to chit chat and insert several comments on how improved the dog is, that it has received medical attention and we are taking care of getting the dog better.
context does matter, but plenty of people will stop and see a bald dog covered in scabs and think you're responcible for it's condition instead of thinking that the dog is with you to recover for it's condition.
