Which breed of dog, Trigg Hound or Welsh Springer Spaniel, were relatively unknown until a succession of victories in dog trials by the breed increased its popularity?

Popular sire effect The popular sire effect (or popular stud/sire syndrome) occurs when an animal with desirable attributes is bred repeatedly. In dog breeding, a male dog that wins respected competitions becomes highly sought after, as breeders believe the sire possesses the genes necessary to produce champions. The popular sire is often bred extensively with many females. This can cause undetected, undesirable genetic traits in the stud to spread rapidly within the gene pool. It can also reduce genetic diversity by the exclusion of other males.
