Harrison Yates' pet lamb, Lamb Lamb, is recovering at home in Hornby after being attacked twice by neighbouring dogs.

Two Christchurch brothers are fearful another attack is imminent after their pet lamb was attacked twice by a neighbour's dogs.

Brothers Joel, 31, and Harrison Yates, 22, brought a lamb, who they named Lamb Lamb, to their Hornby property after it was rejected by its mother in October.

Joel Yates returned home about 1am on November 18 and was horrified when he looked out the window and saw two dogs, a jack russell and a American pit bull terrier, viciously attacking his pet.

JOSEPH JOHNSON/STUFF Lamb Lamb was attacked twice by two dogs from a neighbouring property.

The smaller dog was biting into Lamb Lamb's stomach, while the bigger dog had its mouth clamped about the lamb's throat.

Joel Yates said he rushed outside and pulled both dogs off Lamb Lamb. He struck the pit bull numerous times before it turned and bit the bottom of his jeans. He escaped without receiving any injuries but Lamb Lamb was not so lucky.

SUPPLIED Joel Yates holds Lamb Lamb after it was attacked on November 18.

Joel Yates said no-one in the flat slept that night as they held pressure on the lamb's wounds until they could take it to a vet at 7am.

The second attack happened 12 days later at 10.30am. The brothers were away from the property but their flatmate saw the attack and was able to wrest Lamb Lamb from the dogs.

The pit bull was believed to have jumped the 1.8-metre-high corrugated iron fence at the back of the property while the jack russell dug under it.

SUPPLIED The Yates brothers stayed up all night after the November 18 attack to put pressure on Lamb Lamb's wounds.

Harrison Yates said everyone was traumatised by the ordeal, which left Lamb Lamb "savaged".

"I'm used to hunting but I've never seen so much blood."

The brothers often had trouble sleeping at night as they were constantly checking on Lamb Lamb.

Harrison Yates said the lamb was well known in the neighbourhood and a 6-year-old-girl often visited to bottle feed it.

"If [the pit bull] can jump a 1900 millimetre fence it can maul a little girl," he said.

Christchurch City Council head of regulatory compliance Tracey Weston said both dogs had since been classified as dangerous. Their owner would have to make upgrades to their property, including ensuring the dogs were kept "under lock and key".

SUPPLIED Lamb Lamb suffered further injuries in a second attack by the same pair of dogs 12 days after the first attack.

"The dogs are currently being held in the animal shelter until staff are satisfied that these requirements have been met."

Harrison Yates said he was pleased with the outcome but wished animal control had notified him directly.

"It would of been nice knowing instead of being told it was under the Privacy Act."

SUPPLIED Lamb Lamb is lucky to be alive after the two attacks.

The brothers' father, William Yates, said he had no confidence the dogs' owner would follow any conditions that were imposed.

The dogs' owner paid the $87.60 vet bill after the first attack on Lamb Lamb, but the Yates brothers still had more than $500 to pay for treatment and cleaning following the second attack.

Lamb Lamb will be moved to the Yates' family farm in Picton to live out the rest of its life.
