John Baldwin was seen running over the puppy’s paws on a push bike and dragging it around aggressively in North Harrow on March 27.
In the same video the 39-year-old is seen racially abusing a woman who challenges him on his behaviour, calling him a “bully”.
The video was shared online and within hours members of the Animal Welfare Investigation Team, a non-profit organisation that operates across the country, was able to track Baldwin down.
He surrendered the puppy, Harley, who now has a happy home with her traumatic past just a “distant memory”.
Baldwin, of Apsley Close, was later charged with causing unnecessary suffering and a racially aggravated public order offence.
He denied both charges but was found guilty following a trial at Willesden Magistrates’ Court.
On Wednesday, October 29, Baldwin was sentenced to 14 weeks in custody.
District Judge Walsh said Baldwin showed a total disregard for the dog’s welfare by dragging it aggressively and forcefully lifting it from the floor.
The judge added that the offence was aggravated by his use of a racial slur against an individual who stood up to him.
The court banned Baldwin from owning or keeping any animal for five years.
Sammy Wilkinson, one of the Animal Welfare Investigation Team’s front-line responders, told the Harrow Times the abuse of the puppy was “horrific”.
He added: “I am pleased to hear that he has been given a ban and custodial sentence.
“I will never forget picking up her little body and carrying her out of there, she has been given a new identity and has absolutely flourished in her forever home and continues to go from strength to strength.”
