An Austin police officer was forced to shoot a collarless male pit bull that lunged at him on Monday afternoon, according to Austin Police Chief Brian Krueger.

Krueger said the officer responded to a call at 1:08 p.m. on Monday that said a collarless pit bull with a white head and black body was trying to get into a fenced enclosure with two smaller dogs inside in the 2100 block of Second Avenue Southeast.

The caller said he tried to intervene and get the pit bull to leave, but the dog acted aggressively toward him.

When the officer arrived, he spoke to the caller; the caller’s wife gave the officer a treat to give to the dog.

When the dog approached, the officer tossed the treat at it, but the dog, according to the report, got aggressive and lunged toward the officer, who backed up and shot the dog.

The officer’s supervisor met with the caller, who confirmed the pit bull was being aggressive and tried to attack the officer, according to Krueger.

The dog’s body was taken to the animal shelter. It is unknown who owned the dog.
