CALGARY - Calgary officials say they want to remind people about being responsible for their pets after four serious dog attacks in five days.

A girl was bitten Wednesday by a pitbull-type dog, leaving her with injuries to her left leg and right calf.

Calgary's animal and bylaw services says the owner and the dog fled.

On Monday, a Great Pyrenees attacked two children, and the dog's owner is facing five bylaw charges.

Two dogs were killed in two separate attacks last Saturday and Sunday, and owners of the attacking dogs are facing several charges.

Alvin Murray, manager of animal and bylaw services, says in serious cases the owner must appear in court and punishments include mandatory obedience training, public muzzling, fines up to $10,000, or euthanasia of the attacking dog.

"This influx of aggressive dog incidents raises important questions about aggressive dogs and citizen safety," Ryan Jestin, director of animal and bylaw services, said in a news release.
