bulldogs aren't the only dogs that catch.
i have had airdales, curs, stag crosses, and have seen bird dogs, and hound crosses that will all range out, hunt for, and strike a hog and have never ever bayed. if a dog consistantly strikes hogs, you can call him a strike dog, wether or not he bays or catches. just because a dog is a strike dog, doesn't mean he is a bay dog.
X2 my ridgeback pit will hunt 300 to 400 yards and finds his own hogs. He runs step for step with my hound crosses and does not bay. If he is finding hogs he is a strike dog. My other dogs can find a hog also so he doesn't start every hog. I would call him my top dog tho.
