Every year more than 4.5 million Americans, more than half of them children are bitten by dogs, said the American Humane Association ahead of National Dog Bite Prevention Week, which begins Sunday.
Insurers paid more than 483 million USD in dog bite claims in 2013. Plastic surgeons performed 26,935 operations to repair injuries caused by dog bites. And the US Postal Service said 5,581 of its employees were attacked last year.
"Everywhere needs to take the situation very seriously," said Stilwell at a media event in Washington attended by Elle, a mellow therapy dog that happens to be a pit bull.
Stiwell appealed for greater education and awareness among dog owners and the public as well as better-trained dogs.
In a surveillance video going viral on YouTube, four-year-old Jeremy Triantafilo of Bakersfield, California is seen being attacked and badly bitten in the leg by a pit bull-looking dog.
