Obesity is the biggest concern — Beagles love food and gain weight easily. Hip dysplasia and IVDD (intervertebral disc disease) can also occur; ear infections are common due to their floppy ears.
High-quality small/medium-breed puppy formula until 12 months. Three meals a day under 6 months, then two. Stick to portion sizes — Beagles will always act hungry.
Short, low-maintenance coat. Weekly brushing is enough for most Beagles; check and clean ears regularly.
Scent-driven and food-motivated, which makes them easy to train with the right rewards but easily distracted by smells on walks.
The Beagle is a small-to-medium hound originally bred in England for tracking hare and other small game. Known for their strong sense of smell, intelligence, and a curious, merry temperament, Beagles are among the most popular companion dogs in the U.S.
They're loyal, good with children, and tend to be vocal — traits that reflect their history as pack animals and scent hounds. There are two size varieties: 13-inch and 15-inch, based on height at the shoulder.
