Absolutely True. I know of quite a few incidents where the coyotes have actually called a dog into the woods or into a field like they where going to play together only to have the coyotes have the dog for dinner. I noticed more of the coydog type coyote when they first started commign into the area. There are a few farmers around that say they still see a couple coydogs but for the most part there are just plane old yotes running around but the populations are just getting out of control in a couple areas. We need to get a couple more predator hunters out there to help control the population. I rank calling for fox and coyotes right up there with bow hunting for whitetails. Love It!
