There is not much that is more fun that hunting beagles. I used to handle the dogs for an old man who had at least 100 of them. We hunted 10-15 at a time. Release the hounds! Lot of fun.
However, not much fun if they run a deer and you have to go catch them.
I climbed up a very high tree stand one day and watched the beagles run a swamp rabbit for 30 minutes - it was very enlightening. The rabbit doesn't run much - it darts off and hides until the dogs find it, then repeats indefinitely.
