New Westminster (where I live) has the highest population of coyotes in the Lower Mainland and my condo faces a park. Last night about 10pm I could hear them howling which means they've caught something. It was so disturbing I had to close my balcony door. I have heard that they will not go after anything their size or bigger so I would assume that big dogs are safe, but who knows.

All the more reason to have indoor pets.
