A concert fundraiser to benefit the Butler Police K-9 program on Saturday raised $7,000.

Between 300 and 400 people attended the event at the Kelly Automotive Park. Nine bands were scheduled to pay from noon on.

The city has two police dogs — Gunner and Blade. The German shepherds are handled by officers Brian Grooms and Dave Villotti, respectively.

Villotti said the fundraiser was a success.

“Everybody that was there had a good time,” Villotti said.

The city has spent $101,000 on its two K-9 officers since the program was started in 2012, according to city records. All of the money has come from private donations, T-shirt sales, and fundraising dinners.

The funding goes to covering expenses for everything from dog food to safety equipment for the officers.
