I have a retired and spayed Bulldog, who I showed until she got her championship. Will show her again at the Bulldog Nationals in the Veteran class when she is eligible. Bulldogs are definitely not the breed you want. Years ago (when they were considered rare in the US) I owned and showed Rottweilers. They would be a breed to consider, but they are so overbred now, and have some serious health issues (lots of cancer) I won't get one again.
The dog I DO love and will get again in the future, is another Bullmastiff, or possibly a Tibetan Mastiff. Lucas, in my avatar, is the best, most solid, smartest, full of common sense, funniest easiest to train dog I have ever had the honor to own. He has been a therapy dog for four years - just retired because he lost his right eye to glaucoma. So sad for all of us. He is a very special guy.
