CALGARY — Paramedics rushed a woman in her 30s to hospital after she was bitten Saturday by a pair of large dogs that also killed a smaller dog on a footpath in the city.

Emergency crews were called at about 1:30 p.m. after a pair of bull mastiffs attacked a schnauzer while they were being walked by their owners.

“A woman in her late 20s with an infant in a stroller was walking with her schnauzer on leash and another owner with two bull mastiffs, also on leash, crossed paths,” said Andrew Bissett, manager of bylaw and animal services.

“At that point, one mastiff slipped the leash somehow and went right for the schnauzer.”

The owners tried to pull the dogs apart and a number of people passing by also jumped in to help — including the woman who was injured.

The woman was bit on her arm and cheek, Bissett said.

The woman was taken to hospital in stable, non-life threatening condition, said EMS spokesman Adam Loria.
