A DOG groomer has been sacked after a video that appears to show her being abusive to animals has gone viral. 

Bosses at the groomer’s described the clip that’s surfacing as unacceptable and a probe is underway. 

Shocking footage, seen by The U.S. Sun, shows an employee appearing to hit the animals. 

The worker at the Classy Critters Resort and Spa in Mooresville, North Carolina, was seen punching one animal, and slamming another into a table, as reported by the CW affiliate WCCB-TV.

The video was reportedly captured by another staffer.

The owner of the groomer’s, only known as Pam, said the incident “breaks her heart,” according to a Facebook post.

“This behavior is totally unacceptable, and it was addressed immediately this employee no longer works at Classy Critters,” she added.

“I have zero tolerance for any type of abuse with the animals in my care.

“I have made this clear with my employees.This has been my life mission for over 40 years and I absolutely love what I do, I love and care deeply for all of them and it breaks my heart that this happened.

“I hope that the actions of one bad egg does not reflect on Classy Critters and the entire staff.”

Pam said her staffers give “120% love” to the dogs they take care of.

The woman accused of being abusive has been reported to cops and the local animal control unit.

Police are yet to make any arrests.

But, a representative for Iredell County Animal Services say the investigation into the video is underway.

The agency said it takes animal abuse allegations seriously.

The video, which circulated online and has been watched more than one million times, sparked fury.

A Change.org petition calling for the grooming facility to be shut down has since been launched.

More than 1,500 people have signed the petition.

Classy Critters offers daycare and grooming services.

The services offered to pets include baths, nail trimming, ear cleaning and truth brushing.

The facility has artificial turf yards and indoor playrooms for dogs to enjoy.
