A dog who spent eight years using his nose to sniff out explosives was filmed completing its final job before retirement – with an adorable surprise.
Sniffer dog TTirado, who worked for the Transportation Security Administration in the US, has now been adopted by his handler Keith Gray.
Footage shows TTirado sniff around the airport before honing in on a red suitcase.
He then sits in front of the bag, wagging his tail.
Suddenly 100s of tennis balls are dropped from above and the excited dog tries to catch one as he is surrounded amid cheering and whooping from spectators.
The adorable video has been watched more than 400,000 times since it was shared on Twitter and been “liked” 17,000 times.
“Congrats and happy retirement to the goodest of boys,” commented a delighted dog-lover.
Someone else tweeted: “He has a full retirement stock of new tennis balls.”
“Awww, he’s a good boy and a big sweetie!” tweeted a third viewer.
TTirado is named in honour of Hector Luis Tirado, a 30-year-old New York firefighter who died in service during 9/11 in 2001.
Popular breeds used as sniffer dogs include members of the retriever family, German shepherds and beagles.
These pooches have a super-enhanced sense of smell thanks to generations of selective breeding.
