K-9 (1989)

Dooley: Alright, let's get one thing straight: The woman is mine! Now we're both members of the animal kingdom. You know that and I know that. And we both know that this thing is really primal. So if you think you're such a badass you just try that one more time and you're gonna end up in a pet cemetary! You remember the movie Old Yeller? You remember when they shot him in the end? I didn't cry! Now come on.

Lyman: Dooley, what is it about me that makes you so passionate?
Dooley: Well, it's not your looks, Lyman. I guess it's your job.
Lyman: And knowing your methods of law enforcement, I don't suppose that you have a search warrant?
Dooley: Dog ate it. You can hang around his tail for an hour.
