Need a Catch Dog

In need of a real good 100% guaranteed catch dog. Don't want started dogs. Looking for something that has caught "LOTS" of hogs and guaranteed to catch and not let go. Must be 100% guaranteed. We are taking some young kids hog hunting and letting them stick the hogs. Dog must be a solid no B.S. catch dog. Don't care if its pit, dogo, cross or whatever. Must get along with other dogs, ride in the box with other dogs, no broken teeth, no bad habits, no barking on the 4-wheeler when strike dogs are out hunting, etc. Don't want old dogs. Want somthing with some size to it because I only want to take care of and keep one catch dog. Has to be big enough to handle a big boar by itself. Only want hard hitting serious dog. Post your replies and I will call you. I will want to see the dog catch something before I buy it. NE Texas / SW Arkansas area.
