not at all, my father ran 3 dogs out of ch general in the early 80s. All we're fine with dogs , th dog aggression Is turnt into prey drive an gameness into tenacity.
Every single bull x my old man bred, had to be kenneled seperately, work single handed, and they where out of a 1x and 2x winner...... its the same with everything..... and your saying the bull brings the prey drive? Dont think so, greyhounds prey drive is crazy
i think its common sense to kennel any dog separate regardless of cross and has for having dog aggressive bull xs i think you need to question your old man training n
