All these old bloods that are spoken of today no longer exist it is left up to us work with and creat better dogs for tomorrow wether there blue or not.
Not only do they still exist but there are certain people who have a yard full of dogs bred directly off those old bloodlines..
A dog that will catch a hog is not necessarily a "gamedog" that's why there are people who have blue dogs that work perfectly fine for catchdogs along with a lot of other color bulldogs and also different types of dogs such as dogos and american bulldogs that will work as catchdogs.. They will work as catch dogs but they are not necessarily game in the true sense of the word.. I would say 95% of the dogs being used for catchdogs are not game..
