The study was conducted by experts from Animal Friends who are involved in animal insurance. It was found that the labradors called the best friends of the children had been sworn by postal enemies, with nearly a third of the incidents involving couriers and mail officers. Labrador men bit more women. In 2015, only the Royal Postal Service recorded 2,6,000 attacks on its staff.

According to an animal psychology specialist Roger Magford (Roger Mugford), dogs attack home-born strangers, taking them as a threat to their "stae" family. The summer of the attack is 10 per cent higher when children and domestic animals spend a lot of time in the garden.

Magford advises the mailmans to make friends with local dogs and buy them out. In his opinion, dogs remember people well and will not bite someone who treats them well.

The most common impact of the attacks is amputation of fingers, rubber education and nervous shocks. In addition to the Labradors, people are most likely to be attacked by German sheep, saffordshire bulteries and Border-Colly.
