A volunteer firefighter in Texas resigned Wednesday after a photo appeared on social media indicating that he shot two dogs -- black and yellow labs -- because they entered his yard.

Fox4News.com did not identify the firefighter, but cited a Facebook post that showed two dogs lying on an icy patch. The caption read, "Somebody didn't put any truth (sic) my warning. Keep your damn dogs on your property."

The Hunt County firefighter could face animal-cruelty charges.

The fire department issued a statement saying, "We do not condone the recent actions of one of our firefighters. We are following our policy in removing him from our department."

The station contacted the dogs' owner, who learned that the dogs were shot on social media.

"I'm in shock! I don't know, I don't understand these people. Bad people, I don't know,"  Pulido Rodrigo told the station.

According to state law, in order for a person to legally shoot a dog, there must be a reasonable threat to someone or livestock.
