When his girlfriend refused to pick up his dog's excrement from the kitchen floor, Dunedin's Jayden Lombardi picked it up with his bare hands and chased her through the house with it.
The 19-year-old then encouraged his pitbulls to attack two police officers when they were called and found him on a bed with a bleeding hand, Dunedin District Court was told on Thursday, the Otago Daily Times reports.
Police prosecutor Sergeant Graeme Evans said Lombardi and his partner, Charlie-Joy Beattie-Creed, were arguing about who should pick up dog excrement from the kitchen floor.
She refused and an aggressive Lombardi, who had been on tight bail conditions for five months, picked up the faeces in his bare hands and chased her.
She ran from the house but returned and locked him out. Lombardi smashed a window to get back in and Ms Beattie-Creed called police.
The two officers arrived and saw Lombardi asleep on his bed, with fresh blood coming from a hand wound.
When they asked him to come outside a large pitbull, named Killer, jumped through the open window and ran off.
The officers went to restrain a confrontational Lombardi and his two smaller dogs "jumped into the act".
The dogs were pepper sprayed but Lombardi encouraged them to attack both officers and they were bitten.
Lombardi, who admitted using the dogs as weapons, resisting officers, and intimidating his partner, was sentenced to 180 hours' community work.
The two smaller dogs were put down and Killer is still missing.
