(((hugs))) to the dog and dog owner
About 30 mins+ drive away, they are having coyote trouble. They are seen on highways not just the back roads. Many cats have gone missing lately. My friends have sheep. First llama (which guards their sheep)
I lost a little Lhasa Apso to coyotes when we lived on the Rez in Nevada.
Sometimes, we hear the yelping of coyotes just north of my upper pasture, and one neighbor has lost a cat or two in recent years. Even though I'm completely fenced in, I keep aware of any wild critters who might be roaming around. When the horses are in the pasture during the day, they'll send out an alarm to let us know. At night, when the pastures are enpty, I only let my dogs out long enough to go potty, and they are back inside, safe and sound. I'm usually out there with them, as well.
I'm sorry your neighbor lost his little dog to a coyote attack. It's a cruel way to find out the dangers of their presence.
