You'd be suprised at what a small 20# terrier or two can handle. Breeding and denning is prime time to use a terrier for coyotes. You just have to know how to use them right. My terriers earn their keep during denning season.
I really don't understand how guys get all hurt when someone disagrees with how their dogs work. Too much drama. I could care less if no one here likes how my dogs work. If your dog works for you thats great, your the guy buying the feed and living with it. Getting all upset because someone called another guys dog a "catch dog" is crazy. Given enough time and coyotes in front of a dog, all will have the oppurtunity a couple times to lock up, it's part of the game. All my dogs are part catch dog, part decoy dog, part retriever, part bird dog, part cattle dog(except the terriers, those hard headed SOB's wouldn't work cattle if I bribed them with steak), part lap dog, part truck companion, part watch dog......you get the point. I wish I had room for 50 different "specialists" but the way it is I am always tight on kennel space and I need my dogs to be versatile to MY needs not a one trick pony. Even if it's the best trick you could imagine, they still need to be more and do more. Most of the breeds we consider traditional decoy dogs earned their keep by being a versatile dog first and a good coyote dog second.
Hope everyone has a good fur season. Still a great time to get out and get after the Young of the year coyotes while they are still uneducated.
Keep after them.
