The student bravely stepped in to save his Labrador’s life when it was attacked in an alleyway off Brook Street on June 5.
He suffered more than a dozen bite wounds and his dog’s neck was split open during the attack, but fortunately she survived.
On Thursday (March 6) Callum Clements, 26, of Mulgrave Road in Woolwich, was given a 24 week prison sentence suspended for 18 months.
Clements was also told to pay £500 compensation.
Willesden Magistrates’ Court also ordered that the Pit Bull, named Nina, be destroyed.
Prosecutor Kulvinder Gill previously told the court: “This was a quite horrific incident which happened in an alleyway near the complainant’s home.”
The student was getting ready for college when his sister called him to the alleyway, Ms Gill said.
She told him a Pit Bull had appeared in the alleyway and was acting aggressively.
When he arrived the Pit Bull, named Nina, launched an attack on their dog, Sasha, biting her around the neck whilst shaking, the court heard.
He described the Pit Bull as “foaming at the mouth” as it attacked Sasha.
He kicked the dog to try to get it off before putting his hand over Sasha’s neck area to try to protect her.
“I felt the dog was going for the kill, so I put my hand around her neck to protect that area,” he said in a victim impact statement.
The attack came to an end after several minutes when a member of Clements’ household came out with a rope to secure the dog.
As well as being in control of a dog which caused injury, Clements also pleaded guilty to possessing a fighting dog.
Willesden Magistrates’ Court heard that Clements was unaware that Nina was a banned breed Pit Bull when he got her.
He said he was extremely remorseful for the attack.
