Attached by a pack of, um, dogs

The San Francisco Chronicle newspaper reported:
"A police officer escorting a teenager home from a traffic stop Thursday morning was attacked by a pack of Chihuahuas at the front door of the boy's home. The officer suffered bite wounds to his ankles, was treated at Washington Hospital and returned to work within two hours, Fremont police Detective Bill Veteran said."

This seems a bit funny. I have trouble seeing how a pack of Chihuahuas could be that dangerous...

San Francisco Chronicle新聞によるとカリフォルニア州のフリモントという町の警官が犬の群れに襲われたそうだ。でも犬はチワワだった。足首だけを噛んだ。アイフルのチワワはあぶなそうだか？ちょっと可笑しいだね。
