A man's future as a North Carolina state trooper hangs in the balance as a video of his K-9 partner’s alleged abuse was played at his court hearing that began on Monday.

Charles Jones, a former sergeant in charge of K-9 training for the Highway Patrol, sued the state following his dismissal, which he says violates procedure, FOX affiliate WRAL reported.

Jones was fired after a fellow trooper handed authorities two 15-second cell phone video clips of him allegedly abusing his K-9 partner, Ricoh, WRAL.com reported.

Court documents obtained by WRAL.com said the incident began when Ricoh refused to release a chew reward. One of the videos shows Jones tying the dog's leash to a high railing so that only the animal’s hind legs touched the ground. He then kicked the dog's leg four times.

Jones' lawyer, Jack O'Hare, told WRAL.com that the video clips show Jones using training techniques that have been taught by the Highway Patrol. Ricoh was a particularly aggressive dog that required extra training, O’Hare said.

The hearing was to reconvene on Tuesday.
