Multiple dogs in Toronto’s east end required medical attention after consuming a possibly hazardous material, police said Saturday.

Toronto police say they responded to reports of a “suspicious incident” after the potentially harmful material was located in Taylor Creek Park Friday evening.

“The dogs located a peanut butter jar with an unknown substance mixed into the peanut butter,” officials said in a release.

Mark Rullo told Global News he was walking his dog and a neighbour’s dog when they encountered the material.

He said the peanut butter caught the attention of the dogs and he noticed the unusual contents of the jar when he attempted to get the dogs away from it.

“I was panicking when I saw it, because there were little pellets of things and little bricks of things inside, so it looked like somebody had intentionally mixed something in,” Rullo said.

He said both dogs were taken to the vet for treatment.

Luckily, the dogs are doing well, he said. His dog will be on medication for the next month as a precaution.
