Police and the Hamilton/Burlington SPCA are investigating after someone captured video of a woman apparently pressure washing her dog at a car wash.

It happened just after 6 p.m. Thursday. Karliegh Heatley, a Hamilton resident, says she pulled into a car wash at King and Wentworth with her fiancé to wash her car.

She noticed a woman using a pressure washer to bathe a dog, which was yelping, Heatley said. She got cell phone video before she approached the woman and told her to stop.

It was then that the dog owner caused "a disturbance," Hamilton police say. Officers responded.

The dog owner told the officer that the animal had just rolled in the mud. She didn't believe she was harming the dog, police say, because she used a low water setting.

Investigation revealed the dog wasn't hurt, police say. But "the woman was given advice regarding the choice and perception (of) using a car wash facility to bathe her dog."

The SPCA is investigating as well.

"Our protection department was made aware of the video first thing this morning," said spokesperson Michelle Macnab. "All information has been passed to our officers and they are currently investigating the situation."

Heatley, meanwhile, posted her video to Facebook, where it's generated hundreds of comments.

When she saw the dog's reaction, she said, "I couldn't just not say anything."

Police are asking anyone with information about the incident to call them, or Crime Stoppers at 1-800-222-8477.
