As a 9-year-old boy’s birthday party was winding down at an Idaho home on Saturday, a police officer fatally shot a service dog belonging to the boy’s father.

At around 5:30 p.m., the officer was responded to complaints of dogs on the loose, which is what he found when he arrived.

Officer Tarek Hassani, of the Filer Police Department, is seen on footage captured by his vehicle’s dashcam kicking and yelling at the barking dogs as he attempted to make his way to the front door. When one of the dogs attempted to move around him, the officer shot the 7-year-old black labrador, named “Hooch,” at point-blank range.

While the police claim the dog was overly aggressive and needed to be put down, the dog’s owner, Rick Clubb, is alleging that the officer was far too trigger happy. Clubb told the Times-News that Hooch was his trained service animal as he suffers from Parkinson’s disease.

“He didn’t have to pull out his .45 and shoot my dog,” he said, also expressing concern that the shooting occurred right outside his son’s bedroom window.

Filer Police Chief Tim Reeves said a chihuahua and two large dogs were running around unleashed in the neighborhood when officer Hassani arrived on the scene. The police chief said his officer had no choice but to put the lab down due to the animal’s aggressive behavior.

Following the shooting death of his dog, Clubb was given a ticket for allowing his animals to run around unleashed. The ticket reportedly led to a heated exchange between Clubb and Hassani.

“Well, my dog is dead. I don’t think that’s fair,” Clubb said.

The father said he plans to fight the ticket.
