Beagles typically weigh between 18 and 30 pounds, with males trending slightly heavier than females. American Kennel Club standards for the beagle do not have specific weight requirements.
The AKC has two height categories for beagles: 13 inches and 15 inches. A beagle measuring taller than 15 inches is disqualified. A beagle's height is measured at the withers, the ridge between an animal's shoulder blades. AKC breed standards call for a muscular appearance in the shoulders, chest, back, hips and thighs, which favors beagles in the middle of the average weight range.
The popular house pet breed descends from the scenthound family, which originated in England in the 1300s, states Animal Planet.
