TL;DR
The typical Beagle lifespan is about 11 to 13 years. In a 2024 UK study of 584,734 dogs, Beagles had a median lifespan of 12.5 years, longer than the 12.0 years of mixed breeds, and a 2025 UK study of 19,906 Beagles found a median age at death of 11.28 years. The breed's biggest everyday problem is weight: obesity was recorded in 24.27% of Beagles in a single year, the most common diagnosis, followed by gum disease (17.78%). Cancer (19.26%) and lumps or masses (13.18%) were the most common causes of death. A Beagle is a senior from about 9.4 years.
How long do Beagles live?
| Measure | Beagle | Mixed breed |
|---|---|---|
| Median lifespan, 2024 UK study (1,552 deaths) | 12.5 years | 12.0 years |
| Median age at death, 2025 UK Beagle study | 11.28 years | |
| Life expectancy at birth, UK life tables | 9.85 years | 11.82 years |
| Senior from about (last 25% of lifespan) | 9.4 years | 9 years |
In the 2025 Beagle study, the middle half of dogs died between 9.32 and 13.08 years. The authors concluded that the Beagle should not be considered a breed of extreme body shape, and that its lifespan suggests reasonable overall health.

This uses the share of the breed's typical lifespan a dog has lived, compared with US human life expectancy of 79 years. For puppies and young dogs, the DNA-based method in the calculator below is more accurate. Try any age:

Human age (DNA method)
64
From age-related DNA changes in Labradors compared with people (Wang 2020). Least reliable for puppies under a few months.
Same point in a human life
53
Your dog has lived about 67% of the typical 12.0-year lifespan for this group. The same share of a 79.0-year US life expectancy is age 53.
Life stage
Mature adult
AAHA: from maturity until the last 25% of expected lifespan, about 9.0 years for this group.
Mixed breed (crossbreed): median lifespan 12.0 years (95% CI 12.0 to 12.1), senior from about 9.0 years.
Lifespans: UK study of 584,734 dogs (McMillan 2024). Life stages: AAHA. Every dog ages differently; health, weight and lifestyle all matter.
What Beagles die of
| Cause of death (2025 UK Beagle study) | Share of deaths |
|---|---|
| Cancer (neoplasia) | 19.26% |
| Mass (lump) | 13.18% |
| Poor quality of life | 12.84% |
| Brain disorders | 6.76% |
Cancers and lumps together accounted for about a third of deaths. Check your Beagle for new lumps every month and have them tested. See skin tags and lumps on dogs.
Common Beagle health problems
| Problem (2025 UK Beagle study) | Share of Beagles |
|---|---|
| Obesity | 24.27% |
| Periodontal (gum) disease | 17.78% |
| Overgrown nails | 11.61% |
| Ear infections | 11.18% |
| Anal sac impaction | 10.59% |
The authors said owners and vets should put special emphasis on weight control and dental hygiene in Beagles.
Weight
Beagles are scent hounds that love food, and nearly a quarter were recorded as obese in a single year. The UK median adult weight was 18.19 kg. In a lifelong study of Labradors, dogs fed 25% less food lived a median of 13.0 years against 11.2 years for their heavier littermates. Measure every meal, count treats, and keep them under 10% of daily calories. See senior dog food for weight loss.
Teeth
Dental disorders as a group affected 21.48% of Beagles in a year. Brush daily if you can. If brushing is hard, daily help in food can slow plaque: in a randomized trial, daily treats containing the brown seaweed Ascophyllum nodosum led to significantly less plaque and tartar over 90 days. Our Daily Dental Cleaning Powder contains 700 mg of Ascophyllum nodosum per 4 g serving and is now available to pre-order.
How to help a Beagle live longer
- Keep it lean: weigh monthly and measure every meal.
- Look after the teeth every day.
- Check and clean the long ears, and trim the nails regularly.
- Check for lumps monthly.
- Give plenty of exercise and sniffing time on walks, which also helps control weight.
- Twice-yearly vet checks from about 9.4 years.
