We have several lines that produce a lot of bloat (and toxic gut lately) and no, not "just" American line show dogs...working dogs bloat, German dogs bloat, different breeds bloat, heck mutts bloat...that said one of the advantages of pure bred dogs is that we are able to study pedigrees and make intelligent (??) breeding decisions. As far as why it hasn't been eradicated, well some people breed away from it and others double and triple up on things...

Are we saying all GSD's that bloat go back to a specific dog or line that is the root of the problem? Seems to me If that were the case it would be pretty easy to eliminate as we would know by now where it is coming from. ============================================================================ POST is Copyrighted 2010.
