The Beagle himself will generally tell you no; left on his own, the adult "house pet" beagle is actually often a fairly lazy animal. The adolescent beagle, however, is an exhuberant creature who will need adequate opportunities to exercise his growing body and mind. The prefered forms of exercise include leisurely walks with their family or a good run while out hunting. Many beagles are enthusiastic retrievers, if taught when young. The beagle also can be a faithful jogging companion if you wish, but it is important to not over-exercise a young animal as you could do damage to the skeletal development. If you like to take walks with your dog or jog, please remember that it is very unwise to take a puppy under the age of 18 months on walks or jogs of more than 1/2 mile as their skeletal systems are not yet solidified enough to take the stress. After 18 months gradually extend the walks a 1/2 mile every week or so.
