Toronto Public Health Spokeswoman Susan Sperling said that since a puppy purchased at a flea market died of rabies, local health officials have been inundated with calls from concerned citizens, The Globe and Mail in Toronto reported Saturday.

"We've had 500 calls to date, but no human cases so far. We've also managed to recover some of the other puppies," Sperling said.

The border collie puppy died at the Toronto Humane Society last week, prompting health officials to recommend that anyone who came in contact with the animal to call for a medical assessment.

The Canadian newspaper said the dog's former owner will likely not face charges in Toronto due to the fact the vendor operates outside the Ontario city and a lack of provincial regulations regarding dog sales or breeding.
