This July 7 surveillance video just released by L.A. County sheriff shows a 10-pound Chihuahua named Paco chasing off a pair of robbers at Ace Smoke Shop in Altadena, Calif.

Two masked men entered the store with an empty backpack and demanded money, pointing the gun at the cashier.

From out of nowhere comes Paco, barking furiously and biting at their legs. For a second, it appears the two robbers were so frightened they were going to leave without the money. But one, after initially retreating, grabs it before they flee, Paco chasing at their heels.

No one was injured — not even Paco — during the incident.

Paco, according to Time.com, was a rescue dog and has been with shop owner Eric Knight for five years.

Knight wasn’t at the shop during the robbery, but was proud of how bravely his dog behaved.

“I’m going to put a cape on him, I think,” he said.

A Canadian couple fell in love on their vacation in Mexico — with a stray dog.

Josiah Allen and Erin Docking were sitting on the beach in Puerto Vallarta when the small white dog came up, sat down next to them and stayed all day long.

By the time their 10-day vacation ended, the couple had determined to take the dog, who they’d named Paco, back to Canada.

They filled out paperwork, took him to a veterinarian for treatment of an eye infection and tick infestation, and paid to get him the necessary shots.

But on their flight home, Delta Airlines somehow lost the dog, the Detroit News reported.

On May 3, the couple placed Paco in a pet carrier and flew from Puerto Vallarta to Mexico City. At the airport there, they ran into trouble getting approval for Paco to fly to Detroit. Airline officials questioned whether the carrier was large enough for Paco but approved him for the flight once Allen signed a waiver protecting Delta from any claims if the dog was injured.

When Allen and Docking arrived in Detroit,  Paco was nowhere to be found.

“After waiting around for two hours, they told us (Paco) was in Mexico City and would be flown in on the next flight,” said Allen, 19, a kinesiology student at the University of Waterloo.

But Paco –  described as a mix between a “wiener dog and a Jack Russell terrier” — didn’t arrive the next day, and hasn’t since.

After Allen went public with the story, Delta officials called and offered to cover the expenses he’d incurred with Paco and throw in some extra cash, Allen said.

“Our staff has conducted exhaustive searches to locate the dog,” Delta officials said in a statement. “We have been in contact with the dog’s owner to inform them of the situation and to offer our sincere apologies that we have been unable to recover the dog…”

Some reports say Paco broke out of his cage at the airport and ran away — meaning he may once again be a stray, only this time in Mexico City rather than Puerto Vallarta.

Pay special attention to the little dragons in the clip above, from the newly released movie, “How to Train Your Dragon.”

The movie from Dreamworks, being shown in 3-D in some theaters, features the voices of Craig Ferguson, Gerard Butler, America Ferrera, Jonah Hill and Kristen Wiig. But for dragon noises, the filmmakers turned to at least one dog — a Chihuahua named Paco.

Paco’s owner posted a video on YouTube of his dog, who he says vocalizes every night before going to bed. Here’s Paco speaking his mind:
