So, let me tell you guys what the Supreme Court has said about a drug dog at your door. The fact that a police officer brings a drug dog to your door can be a violation of your civil rights. That's considered a search under the Fourth Amendment, and it's illegal for them to do so without a search warrant. So, never fall for that. If you see a police officer approaching with his dog, always be sure to tell them, "I never consent to any searches and I don't answer questions without a lawyer.
