Depends, if you have got nothing to hide. Yes i would go to every house around and ask who got a problem. If you do, its best to say nothing before talking/rumors start.

I had police at my door a few months ago. According the officer "A" vet called that i brought allot of pitbulls over the years and mentioned dogfighting so he came and check my dogs. I never brought one with a scar. I did take a red blood test for a female a few days before he came. Fucker.
He didnt had the papers to search my house but i stayed friendly and let him in. showed him a few of my dogs and confirmation/sport prices that i won in the past(good cover up), ect. He was ok with that.
The officer didnt want to mention his name or the clinic. I repeatedly asked. but for me there was only 1 possible. So i called the vet and confronted him with it. I told him i bring my dogs to the vet because i care about their health so why in the hell would you call the police. But he denied he had anything to do with it. Right..
