I never really thought of the ones bred for hunting, as plodders.
Quick, agile and with a flowing gait are desired traits. As with any breed, you will get breeders that work/breed towards different goals. And some will go to the extreme, without thought towards the overall well rounded dog.
Others work to improve their bloodline, but stay within the breed standard.
Vizslas are known to be a closer working dog. So I could see someone describing a trot, as a plod in those dogs. Some have been bred to compete with the bigger running pointers. Those dogs don't trot/plod, they flat out run, and eat up the ground.
Not all those who wander are lost.
Life is just a leap of faith.
Spread your arms and hold your breath and always trust your cape.
Two things define you. Your patience when you have nothing, and your attitude when you have everything.
