The owner of a Vancouver dog stuck on doggy death row is taking a run at the Supreme Court of Canada to try to save the animal's life and set a precedent for other pets deemed dangerous.

A B.C. Court of Appeal judge stayed Punky the Australian cattle dog's execution Friday, giving the owner's lawyer 30 days to prepare a leave to appeal application to the Supreme Court of Canada.

The four-year-old dog has been locked up for two years. Punky was deemed dangerous after biting a woman in an off-leash park in Vancouver in 2017. Since then, owner Susan Santics has waged a legal battle to save her pet.

Punky was scheduled for destruction Aug. 23, but that's now been put off for 30 days.

"Of course I was relieved. I was sitting in tears in the court," said Santics, after the judge initially gave the dog a seven-day grace period yesterday [Thursday]. Today [Friday], that was extended, after the judge considered the arguments to try to take the case even higher and ask the top court for the right to appeal earlier court rulings.

'Transformed legal environment'

Animal rights lawyer Victoria Shroff plans to use Punky's reprieve to prepare a formal leave to appeal application, which must be granted by the Supreme Court of Canada before it will hear the case.

Appeals to the SCC are not automatic. The court only agrees to hear cases involving significant legal issues of national importance.

Thursday, in the B.C. Court of Appeal, Shroff argued Punky's case is of national importance.

"We are in a transformed legal environment where animals matter," Shroff argued.

"Even if you think an animal is not a family member, before you take somebody's property away — especially sentient property — you better be 100 per cent sure that this animal has no prospects of rehabilitation," she said.

Punky's saga

Earlier this summer, three justices of the B.C. Court of Appeal ruled that Punky was dangerous, agreeing with earlier rulings at lower court levels and the City of Vancouver.

"Given Punky's past behaviour, temperament and lack of rehabilitation prospects ... the dog poses an unacceptable risk to the public and ought to be destroyed," Justice Patrice Abrioux wrote.

Punky was scheduled for destruction Friday. But, with the potential for an 11th hour reprieve from the nation's highest court, a legal door has now opened.

Shroff says it's a long shot. The Supreme Court only approves a fraction of the leaves filed each year, but she says Punky's owner wanted to push forward.

The dog's owner and lawyer say they've received overwhelming support from people who have written offering to adopt the dog, help fund the case and even a push by one doctor to have Punky's plight heard at the United Nations.

"This case has garnered international attention," said Shroff. "People in Canada and the world really care about animals."
