The whips and volunteers from the hunt help to train and exercise the hounds. Below is a photo taken of Peter and the hounds after returning one foggy morning after hound exercise. The hounds are trained to only chase fox. Deer scent is strong and it takes a lot of work to teach the hounds to not chase deer. Riders in the field can usually tell whether we are chasing fox or deer.
Deer tend to run straight and fast leading the field on a wild and long gallop.
The whips are usually able to pull the hounds off the deer scent before they get to far away. A fox on the other hand, runs in circles and tends to crisscross and backtrack across it's scent. Of course hounds differ in their ability to hunt fox. The huntsman and whips can recognize the cry of each hound and know which hounds are the best hunters. This hound doesn't seem to be interested in hunting at the moment.
