JMNSHO, but I think health testing is MUCH more important than a championship. "CH"s are not the be all and end all of breeding. Actually sometimes it seems that ONLY breeding for championships is turning many breeds into caricatures of what they were intended to look like. I mean, look at a lot of the AKC Ch. German Shepherds, some of them make me want to cry. English Bulldogs come to mind too.
Jiggs was shown and is now pointed, which shows that she does represent what a Bull Terrier should look like. Also, I do believe that Jo has a lot of mentors in the bully world. If she were going to be irresponsible, she could've just not neutered Zero after she had him health tested and then thrown him and Jiggy together. Obviously, this was a well thought out decision.
I too am surprised by some of these remarks. Congrats Jo on your upcoming litter. I can't wait to see all the little piggies. *hugs*
