Get this dog walker to obedience school.

A dog walker working with Wag, an app-based service for pet owners, was caught behaving very badly during a visit to his clients’ house last Wednesday, when he was filmed raiding the clients’ fridge and sneaking swigs of their booze.

In addition to swigging what the homeowner believes to be milk from the fridge, the worker took a few sips of bourbon from a bottle the Overholts had on the counter. (Brent Overholt via Storyful)

FRENCH BULLDOG'S 'CHUCKY' HALLOWEEN COSTUME IS SCARY GOOD

Brent Overholt, of Streetsboro, Ohio, had signed up for the dog-walking service after bringing home a golden retriever puppy — named Pluto — for his wife Claire, figuring that Wag’s walkers would be properly vetted and trained to walk Pluto while he and Claire were at work, Fox 8 Cleveland reports.

Upon reviewing their security footage, however, Brent found the dog walker to be less-than-professional, rummaging through the couple’s fridge and cabinets, sometimes with his hand down his pants.

At several points through the homeowner's surveillance video, the Wag dog walker can be seen with his hand in his pants. (Brent Overholt via Storyful)

“He drank what we think is milk out of the fridge, and put the milk back in the fridge,” said Brent, speaking with Fox 8 Cleveland. The Wag employee then took a few sips of bourbon from a bottle the Overholts had on the counter.

As seen in the surveillance footage, the man eventually became aware that he was being filmed when the camera fell from the fridge (after he opened it for a second time). He quickly reset it atop the refrigerator and left.

Wag has since confirmed the man was removed from its roster of independent contractors.

“Every service on the Wag! platform is insured and backed by the full support of our Trust and Safety team, which means in the rare case of an incident we will work directly with the pet parent and the appropriate parties," Wag wrote in a statement shared with Fox News. "In this case, we've removed the walker from our platform, so that they can no longer provide services through Wag!, our dedicated Trust and Safety team is in contact with the pet parent to address his concerns, and he has been reimbursed for the cost of the service.”

In addition to the statement, the company also shared a link to its Trust and Safety measures.

Overholt, meanwhile, told the outlet he’s still considering pressing charges against Wag.

"From here on out, for us it's only gonna be friends or family or close people that we know to take care of our dog," he said.
