A three-legged dog who was spotted by a supermarket's surveillance camera helping himself to a treat from the pet food aisle has become an overnight sensation in his home country of New Zealand.

Footage of Oscar's derring-do was featured on national TV, eliciting a flood of calls from animal lovers looking to adopt the German shorthaired pointer.

According to officials in the city of Invercargill, where the now-infamous Dog Roll Heist took place, Oscar appears to have run away from home while his owner was on vacation.

While on the lam, Oscar happened across the Alray Dairy, and wandered in looking for something to eat.

"About 12 minutes past eight we caught him on the camera," said store owner Esmay Hay. "All of a sudden he appears standing looking into the dog chiller, helps himself to a dog roll, drops it on the floor then picks it up and carts it out."

And he would have gotten away with it too, if it weren't for his insatiable appetite for dog roll, which sent him back into the store at least twice that same day.

On his final visit, one of the dairy's employees managed to corner Oscar and tie him up. He was subsequently taken away to a local pound, where staffer have been waiting for his registered owner to come and pick him up.

However, if no one comes to collect Oscar, Hay says there are plenty of people lining up to give him a new home.
