Gritty vs Catchy

I haven't thought about it much but I always thought that gritty, catchy, and rough were pretty much the same thing. To me it means a dog that you can't rely on to catch solid but wants to tear a hog up. We have some rough curs that if you don't get there in time, they will dispatch the hog for you. Mostly the curs that are bird dog x and our big ole cat, Rowdy. I'm glad yall shed some light on the difference between'em. Now we have a cur dog that came from the old line of dogs that were used for hereding hogs back in the day and he bays real loose, he is one of our strike/bay dogs that has been on many big hogs and the only one we own that doesn't have a scar on him.
