The Beagle is classified by The Royal Kennel Club within the smaller ageing band, typically weighing 9–11 kg as an adult, with a median life expectancy of around 12.5 years, according to a 2024 analysis of UK veterinary records by Dogs Trust. Bred as a scent hound for tracking hare, the Beagle is friendly, curious, and driven by its nose above almost everything else.

What this means for your Beagle

Beagles are notoriously food-motivated, which makes them easy to train but also prone to weight gain — keeping treats in check and maintaining regular exercise becomes increasingly important as your Beagle ages and its metabolism slows. Their long, floppy ears also need regular checking, as trapped moisture and debris can lead to ear infections.

The breed can be prone to hip dysplasia, hypothyroidism (an underactive thyroid, which can contribute to weight gain and low energy), and epilepsy. Regular weight checks and blood work as part of senior vet visits can help catch these issues early.

When is a Beagle considered a senior?

Under The Royal Kennel Club's size-adjusted guidance, small breeds like the Beagle are generally considered senior from around 10 dog years old.
