A San Mateo County man bashed in -- apparently with a brick -- the snout of a neighbor's pet poodle , which he complained had wandered onto his property too often, a prosecutor said.

Marcos Montano-Topete, who's due Wednesday in San Mateo County Superior court, faces felony animal cruelty charges for attacking the 26-pound pooch named Globsis, District Attorney Steve Wagstaffe said. The dog underwent emergency surgery, but had to be put down after the assault in unincorporated Redwood City.

Prosecutors said Montano-Topete, 32, had warned the neighbors to keep their 5-year-old dog off his property. On March 26, he decided to take violent action for reasons that remain unclear, according to authorities. Afterward, he allegedly he approached the 16-year-old neighbor girl, admitted the attack and told her the dog was laying in his yard.

When Sheriff's deputies arrived a short time later, they found the animal laying in a pool of blood, whimpering, convulsing, but unable to move, prosecutors said. They also found a brick nearby. The Peninsula Humane Society picked up the wounded animal and tried to treat its injuries, but a decision was made to have Globsis euthanized.

Montano-Topete has pleaded not guilty to animal cruelty and animal neglect, both felonies. He's out of jail on $10,000 bail.

Defense attorney Thomas Deremigio didn't immediately respond to a request for comment.
