CO-Guy , sorry to hear about your friend and buddy being taken by coyotes . When their numbers are high or they have cross bread with dogs they do some strange things as do packs of feral dogs . I do the best that I can to respect life of all kinds but have been known to take life with indifference and remain calm all the while when doing it as it was just a job to be done at that time in my life . That is why some people have called me a heartless ba20-87 for being able to do control work but I can see both sides of that coin as can so many others here . When we go out into the world with the animals we see just how indifferent life can be and how crewel it is to us ,at times . With the advancements in communications from around the world we can see how crewel other people can be to their own kind as well . If memory serves me in the Bible these people are called natural man as they are so much like the beasts of the land . Just my thoughts . This is the time of the year that the control workers get busy as this is the time of the year that the predators are trying to raise their pups . The coyote will be killing other dogs that get too close to their pups in order to protect the pups they don't take into consideration the size of the other dogs they just view them as a threat to the pups . And that is one of the things that as a control worker I used to my advantage and had good dogs to use as live decoys to draw in the adult coyote . If you have never been exposed to the use of dogs on coyote there is a good video called Dogging Coyotes . There is a guy with his dogs in it from Gillet Wy. named Calvin Taylor . He has some good Mountain Curs that are light colored and work coyote well . He ended up with my last female cur when I decided I was too old to finish training her and that it wasn't fair to her for me to keep and not use her . I gave her to a friend of mine here that gave her to him to finish her training . A lot of the coyote dog decoys are curs and some Jack Russell Terriers that make good denning dogs as well . Most of the dogs that are smaller will have a good heavy collar made of layers of canvas or leather and know to come back to their friend with the rifle for help or they don't last at the job long and will be not used again . If you get the time and opportunity to watch Dogging Coyote it is worth it in my humble opinion . Again CO-Guy I am sorry for the loss of your friend and family member , your Rat Terrier .
