"Proud and noble pure bloodlines" basically mean bored people in the 19th and 20th centuries made a bunch of cats and dogs fuck their own relatives over and over to get specific traits they found amusing to breed true. "Purebred" = Inbred.
That a host of genetic problems result from bottlenecking their genepool is, at least in the current era, entirely predictable. That we still speak of cat and dog "breeds" as if they were anything other than something we made up in a period of deliberate animal abuse, is frankly disturbing.
