Why do we run so many bay dogs?

100% agree that allot of ppl blame the hog well i kinda have to disagree maybe its the dogs i don't like rcd not sayin they don't work just not my way i do have some... i think smart dogs catch dogs their are ppl here who run 20 dogs on the ground no lie they still have hogs run on them so you tell me rough dogs work the best id disagree i also know a guy he been huntin 30 plus yrs and runs to dogs on the ground and to lead in catch dogs and catchs more hogs than anyone i know so what im sayin i guess is smart dogs catch hogs however you hunt rough or bay dogs 1 dog or 20 they got to be smart
