I was direct to get my point across but I didn't want to escalate and have him take it out on the dog. Who knows of that's a possibility. If they do in fact keep it out, contacting animal control during business hours will be the best step. Worcester police are not the greatest on following up, and the dog is very clearly on private property and not accessible. It IS a business, so my hope is that my statements will instigate enough paranoia that they will take it seriously.
