People who leave their pets outside, unsupervised, are fools anywhere, but here in the foothills of the San Gabriel Mountains, they'd be
really stupid.
Between the coyotes, bobcats, cougars, bears, snakes, hawks, and other predators, small animals don't stand a chance.
My dogs were anything but small [Great Danes], but they were never outdoors alone, either here or when I was living in Dallas. There are far too many dangers for pets outside, and I didn't/don't want any of mine succumbing to them.
Bears don't typically pose a threat to other animals, especially if they're non-threatening, but even that isn't cut and dry. Just yesterday, a bear attacked a woman who'd fallen asleep in her backyard. She lives a few blocks away from my aunt.
A few months ago, someone was walking their dog, 'next door' in Pasadena, in broad daylight, on a city street, and a coyote snatched the dog. A recent post on Ring detailed a coyote scaling the yard's wall, grabbing the dog who'd just been let out to potty, and carrying him back over the wall. The owners were able to get the dog back from the coyote; he suffered numerous puncture wounds and needed medical care, but did survive.
Sorry for rambling!
