Before I bought my dog I noticed that there were various lines of German dogs. One called German show lines were dogs that were also all Schutzhund titled including the IPO. The working lines were also all titled dogs. Why are they called show lines if 64 dogs on the pedigree were all Schutzhund titled? What is the difference? The show lines did seem to be larger dogs than the working lines. Are they just trying to breed a good looking dog that will also work. Is there a big difference in working ability?
