I used to love seeing a coyote while in the woods. Over the years, the sightings became all too frequent and then friends started losing their hunting dogs. I have beagles and a bird dog, and my view of them has changed.
They are an incredible animal, but the balance of nature no longer exists. Their only natural enemies are gone in my area. The only method left to control them is man. As a result, coyote hunting has become much more popular. Some guys put fast hounds on them to run them to gun. Others, actually breed a very tough, fast dog that will run them down and kill them - usually 2 or 3 dogs on one coyote. I know several coyote hunters who take 50-75 each year. It doesn't seem to make a difference. Their population seems to keep going up.
Within the last month, a guy in my area was walking his two labs in a very rural spot. In his presence, 5 coyotes attacked and killed the 80 lb dogs. According to the dog owner, the coyotes killed these large dogs very quickly. By the time the owner got back with the game authorities, the dogs had been eaten.
I've talked with many coyote hunters and some have taken several coyotes in the 60+ lb range. That's damned near a wolf. In fact, the DEC in New York has documented wolf genes in the coyotes population of this area.
All that said, I personally would have probably not killed the pups, but I certainly would not have faulted anyone who did.
