Beagle: Age, Food, Lifespan, and Health
Beagles are scent hounds with persistent food drive and a strong nose. They're hardy and long-lived overall, with obesity as the single biggest preventable health issue.
Beagle age in human years
Based on the Wang 2019 epigenetic-clock study and the AVMA aging ranges for small-class dogs. The first year of life equals about 15 human years on its own. The seven-year rule is wrong.
| Dog age | Human-year equivalent | Life stage |
|---|---|---|
| 1 year | 15 | adolescent |
| 2 years | 24 | adult |
| 5 years | 36 | adult |
| 8 years | 48 | mature |
| 10 years | 56 | senior |
| 15 years | 76 | geriatric |
Beagle food portions
Daily food at three sample weights for a spayed or neutered adult on light activity, fed dry kibble at 360 kcal per cup. Uses the NRC veterinary RER formula. Adjust up for working or sport dogs, down for couch dogs.
| Weight | Daily calories | Cups per day |
|---|---|---|
| 20 lb | 585 kcal | 1.6 |
| 25 lb | 692 kcal | 1.9 |
| 30 lb | 794 kcal | 2.2 |
Beagles will counter-surf, garbage-dive, and convince guests to drop food. The calculator math is correct, but a Beagle will eat anything not nailed down. Lock the food bin.

How much should I feed my Beagle?
Use the food portion calculator at adjustingstudio.com/paws/tools/food-portion-calculator.
