Umm as for our dogs over here, we used EBT because APBT were not in OZ in the early day and as for great danes they only add size (something wrong with man hood there as the one's i've met, a jack russel would give em an a$$ woopin), years ago i had a pit cross of two different bloodlines as well as bull mastiff blood, and that was one dog that was a very good dog in the end, but so hard headed for the first 18 months of her life. and that why i think people can't or don't know how or how to read/understand and or handle APBT dogs and that makes them not like or want the blood in there dogs. y
