- And we'll begin with Mr. Buck Masters.

- Yeah, yeah, yeah!

- That's right. I've decided not to pay the ransom. I'd rather use the money to catch those crooks.

- I was sure to win first prize at the County Dog Show this year.

- Now Bob Miller's Great Dane is a shoo-in.

- Great Dane?

- Did you say Great Dane?

- Yes. Bob's been grooming his dog for this show all year.

- But if that's the case, isn't the Great Dane in danger? He could be dognapped.

- Don't worry. I warned Bob, and he only takes the dog out for exercise at night, and then only on Beach Boulevard near the police station. It seems safe enough there.

- From now on, all dog owners must be on their guard.

- Mr. Masters, we're gonna find out who's stealing those dogs and why.

- Yep. Dognappers, beware.

- Frankly, I don't see what you kids can do. I don't have a single lead to give you.
