This isn't a debate about cats and dogs. Each have their merits as our companions and fur babies. But if you've ever wondered if dogs can really sense a "bad" person, there's science now that says so.
I've had many dogs as pets (cats too) over my lifetime and I've seen first hand how my dogs just get a sense of when a person might not have my best interest in mind.
Be it an unknown delivery person or a neighbor that acts a little creepy, I've always gotten warning signs from my dog that when it happened, I just brushed it off. But now it's nice to know it's a real thing.
