Authorities have seized four pit bulls they believe were responsible for a series of attacks on southern Vancouver Island and the Lower Mainland, Surrey RCMP said.

The dogs' owner, who has not been identified, was questioned and released by Vancouver police after animal control officials removed four adult pit bulls and a pit bull puppy from his truck Monday morning, RCMP spokesman Cpl. Jack Hundial told CBC News. Janice Levers, of the Surrey SPCA, says the owner of the seized pit bulls is a person of interest in the investigation into several recent pit bull attacks. (CBC)

"The owner has been a person of interest in several attacks in Surrey, regarding a person taking several pit bulls into parks and the dogs being involved in attacks on other animals and [biting] of some humans," said Janice Levers, manager of the Surrey SPCA.

A man walking his dog in a Surrey park Sunday was bitten by more than one pit bull. Victim Jody Tomlinson told CBC News the owner of the dogs didn't even try to stop the attack.

"The dogs just came at us. There were two full-growns and three adolescents," Tomlinson said.

"The two large ones took down my dog … they were pulling her all over the place. The other little ones were biting me and jumping up on my face trying to get me," he said.

"I kept yelling to him [owner], 'Get control of your dogs! Get control of your dogs!'"

Tomlinson suffered only minor leg injuries and didn't require medical attention but his dog was severely injured and had to be taken to a vet for treatment.

Link suspected to Vancouver Island attacks

Meanwhile, Don Brown, the chief bylaw officer for the Victoria’s Capital Regional District, believes the same man and his dogs are responsible for several attacks on Vancouver Island over the past year.

The most recent took place in North Saanich last month, when three pit bulls mauled a dog so badly it had to be euthanized, Brown alleges.

Investigators suspected the pit bulls' owner was living with relatives in Sidney, but left town after the North Saanich attack.

There have been a total of nine pit bull attacks reported in B.C. in the past 11 months — seven in Surrey and two on Vancouver Island. Brown says he would like to see a database created so bylaw officers can share information to track down offenders.

The other attacks on people involved a jogger and cyclist who were injured by pit bulls in separate incidents in Surrey. The remaining five incidents involved dogs being bitten. Two of the animals died from their injuries.

A communications strategy will be on the top of the agenda at a national conference for animal care officials in Banff in October, Brown said Monday.

"There certainly needs to be something, because people are quite mobile in Canada, and they do take their dogs with them," he said.
