Paul Anthony Archer, a resident of Leeds, was seen shouting at Denver, his English bull terrier, while poking him with a hammer before slamming his car's boot on him.
Archer can be heard shouting at the dog to go 'die' in the footage that emerged of the incident.
He appeared before Leeds Magistrates' Court yesterday and admitted failing to meet the needs of his dog.
"Watching the footage, it's clear that Denver is frightened of the way his owner is behaving towards him," said Gemma Fowler, inspector Royal Society for the Prevention of Cruelty to Animals (RSPCA).

The court in mitigation heard that the defendant was cleaning the car when Denver jumped in and broke the screen on an iPad on one of the car seats.
Archer was also sentenced to a 12-month community service with rehabilitation for his unresolved aggressive manner and ordered to pay 750-pound costs.
"We all get angry sometimes, but Archer's behaviour towards Denver is totally unacceptable," Fowler said.
The footage was sent into the RSPCA anonymously. RSPCA is a charity operating in England and Wales that promotes animal welfare.
