I live in a state that is own 98% by the BLM. Which means 98% of NV is wild area for the coyotes, burros, mt lions, bobcats, big horn sheep, etc. There is 45 miles of this empty land (as the coyote wanders)between my house & the next city. I would think the OP lving in Canada, there is plenty of area for animals to roam & feed. Development, I hear, is a problem in CA but its not here.
The carnaviors come to where we live cause people pets are easy food. They have plenty of land & resources, they found an easier meal dining on peoples furbabies. I can put my trash out & they won't touch it. Not good enough for them. People that let their cats/dogs wander gave coyotes a taste & now they like it.
I too love animals. Coyotes are beautiful when they are well fed & have their winter coats. If coyote urine works by all means use it. Or if you see a recently killed by a car one on the side of the road, think about taking it.
Please be outside near your dog, all the time when your dog is out. I've seen these things climb an 8 ft iron fence up hill to get some quail I had in my backyard. They are fast as heck.
Your poor little dog thinks he's got a playmate when all his playmate wants is him for dinner.
