Police in Malmo said they were called to a neighborhood by residents who said a loose canine was acting aggressively toward passersby and had bitten another dog, The Local.se reported Friday.
Officers said they were shocked when they arrived and the neighbors described the aggressive pooch as a Chihuahua, the smallest breed of dog.
"I did think it was going to be a bigger dog than that," Officer Calle Persson said.
Police said they were unable to locate the dog, which fled the scene before they arrived.
"The canine that was bitten is recovering well from the ordeal. We still haven't found the dog either, I guess that could be because of its size," Persson said.
