Updated at 9:25 a.m. Friday: Revised to reflect details about the puppy's return.

Police say a mastiff puppy that two men took from a Mesquite yard has been returned to its owner — after a man who later purchased the dog realized it was stolen.

The theft happened Saturday afternoon and was captured on surveillance video, which has been viewed online hundreds of thousands of times.

Officials said Wednesday night that the investigation into the theft suspects was ongoing. But Chipper, a 10-week-old French mastiff, is home, the dog's owner wrote on Facebook.

Bryan Vazquez told KXAS-TV (NBC5) that he paid $300 for the puppy and had no idea it was the subject of a police search until his wife saw the video online.

"It feels good to have returned the dog and to have everything for the dog to be back where it belongs," Vazquez said, according to NBC5.

Police said the dog was stolen around 2:20 p.m. Saturday in the 5100 block of Milam Road, near Lawson Road and Interstate 20.

Dogue de Bordeaux puppy theft Here is the video of the theft of my puppy. He is a 10 week old, red, dogue de bordeaux named "Chipper". This happened in Mesquite, TX. Thieves might have possible ties to Lubbock or Amarillo. $500 reward for information leading to safe return of "Chipper". UPDATE**** Chipper has been found and is doing wonderful, still waiting on if they have caught thieves. Posted by Ivy Bordeaux on Monday, October 8, 2018

Two men are seen in the footage pulling up to the home in a black Cadillac SUV.

They get out and walk to the fenced front yard. One appears to be talking on a cellphone while the second walks to where Chipper is standing.

The man reaches over the fence and grabs Chipper by the scruff as the puppy squeals and one of the adult dogs in the yard starts barking.

The pair then jump into the Cadillac and speed off.

Matt Ivy, a Dallas firefighter who breeds the dogs at his home, told KDFW-TV (Channel 4) that he fell in love with the breed when he was a kid.

"It's my life outside the fire department," he told the station, adding that he learned about the dog, also known as a Dogue de Bordeaux, in the movie Turner & Hooch. "They told me, 'That's just a mutt, you'll never find one.' Flipped through a dog book 15 years ago and found them. Did my research and got them. Been in love with them ever since."

Ivy said Chipper was the last of his litter and is microchipped. On his Facebook page shortly after Chipper's return, Ivy said a family from Dripping Springs had adopted the puppy Thursday.

Mesquite police did not provide detailed descriptions of the dognappers. Anyone with information about the incident is asked to call Investigator J. Halbert at 972-216-6794.
