In Camas WA our neighbors 15 pound dog was killed and shredded by a coyote during night.
About the only good I can think of in the resurgence of coyotes is that they commonly prey on rodent and feral cat populations, the reduction of the latter being much to the benefit of wild birds. Florida has a harder time of it in that pythons have become established in the wild and are also devastating native birds in much of the Everglades.
With pythons and other wild invasive species like monitor lizards, iguanas, giant Gambian rats, rhesus monkeys, snakehead fish, walking catfish, and the occasional piranha, Florida is becoming a subtropical experiment in evolution.
