IF it was on the color of the Police Gazette than it was a game dog because the best of show in those days was side by side with the . Best in show, gamest in show.. So on.
IN the beginning of UKC the dogs automatically had to win 2 against a dog that had already won once or twice.. Dog matches quit being put in the Police Gazette shortly after WWII when american boxing started to REALLY come on board. IT was always a gentlemens sport despite what propaganda says. Of course there is always a bad apple involved in any sport, especially contests...
7 generations is how many ancestors contributed DNA (mtDna and Dna goes back 1000s of yrs) from 256 ancestors each giving the dog a DNA source from 20,000 + potential sources. Its the same for all mammals.
Keepin it all in line is just that
Keeping the Gene pool strong .. done right with diversity stemming from the same source can be the strongest source of DNA for any of the breed.
