Ideal Weight for a Beagle: Chart by Sex and Age
A healthy Beagle usually weighs about 20-25 lb. The AKC classifies the breed by height (13-inch and 15-inch varieties), not weight, and because Beagles are famously food-driven, portion control is the main defense against obesity.
Beagle ideal weight by sex
| Sex | Ideal weight (lb) | Ideal weight (kg) |
|---|---|---|
| Female | 20-23 lb | 9.1-10.4 kg |
| Male | 22-25 lb | 10.0-11.3 kg |
Size class: small. Weight-gain risk for this breed: High.
Why the number matters less than body condition
A weight chart is a starting range, not a verdict. Two healthy Beagles can sit pounds apart depending on frame and height, so the reliable test is body condition: can you feel the ribs with a light press, and is there a waist when you look down from above?
The AKC splits Beagles by height into a 13-inch and a 15-inch variety rather than by weight, but healthy adults generally run about 20-25 lb, with males a touch heavier than females. Bred as a pack scenthound, the Beagle is a relentless, opportunistic eater, and that food drive, more than frame, is what pushes so many pets over their ideal weight.

Beagles are among the most obesity-prone breeds precisely because they will eat whatever is in reach and rely on the owner to ration it. Surplus weight strains the back and joints of this sturdy little hound and can aggravate a tendency toward intervertebral disc problems. The breed also sees hypothyroidism, which itself causes weight gain, so an unexplained rounder Beagle warrants a thyroid check rather than just a smaller bowl.
Rough daily calories across the Beagle's ideal range
| Body weight | Maintenance (kcal/day) | Weight-loss target (kcal/day) |
|---|---|---|
| 20 lb (9.1 kg) | 585 kcal | 293 kcal |
| 22.5 lb (10.2 kg) | 640 kcal | 320 kcal |
| 25 lb (11.3 kg) | 692 kcal | 346 kcal |
Orientative only, for a spayed/neutered adult, using resting energy (RER = 70 × kg^0.75) and AAHA/WSAVA maintenance factors; weight loss follows the AAHA rule of 0.80 × RER of the target weight. For your dog's number, use the dog calorie calculator and see the full methodology. Confirm any weight-loss plan with your veterinarian.
