Search for beagle health problems and most guides give you the same list: cherry eye, hip dysplasia, hypothyroidism, epilepsy, back problems. Those conditions are real in dogs generally. But a 2025 study of ordinary pet beagles at UK vet practices found that the problems beagles are actually brought in for are much more everyday.

Researchers at the Royal Veterinary College's VetCompass programme (led by Dan O'Neill) analysed anonymised records for 19,906 beagles, then reviewed the full clinical records of a random sample of 3,729 of them. The paper is open access in Companion Animal Health and Genetics (2025). This article walks through what it found and what it means for you.

The five most common problems

Share of the sampled beagles diagnosed with each problem during 2019:

Problem Share of beagles
Obesity 24.3%
Periodontal (gum) disease 17.8%
Overgrown nails 11.6%
Outer ear infection (otitis externa) 11.2%
Anal sac impaction 10.6%

Grouped more broadly, dental disorders affected 21.5% of beagles, ear disorders 13.6%, skin disorders 10.9%, and tumours of any kind 10.9%.

The pattern is clear. Nearly all of the most common problems are preventable or manageable with routine care: weight control, tooth brushing, ear checks, and nail trims. These are things an owner can act on without a diagnosis.

Weight comes first

A quarter of beagles in the study were recorded as obese, the single most common diagnosis. The authors write that beagles appear predisposed to obesity and recommend good weight control. The breed's food drive is well known, and a trusted second source, the WSAVA breed profile, also lists obesity as a predisposition and notes it raises the risk of disc disease. See our guide to how much a beagle should weigh.

Ears and teeth

Ear infections affected about one in nine beagles. Long, folded ears hold moisture and limit airflow, which is the usual explanation. Signs include head shaking, scratching, odour, and redness. Check ears weekly and ask your vet which cleaner suits your dog, since cleaning an already-inflamed ear can make things worse.

Gum disease affected about one in six. Dental care is the most under-used lever in dog health: daily brushing with a dog-safe toothpaste is the standard recommendation, and your vet can tell you whether your beagle needs a professional clean.

What about the serious conditions?

Some of the better-known beagle conditions are less common than guides suggest, and a few weren't prominent in this dataset at all.

  • Seizures: 2.0% of sampled beagles had a seizure disorder, more often in males (2.8%) than females (1.1%). A related inherited form, Lafora disease, is a late-onset progressive epilepsy that the WSAVA says begins from around age five and can be hard to control with drugs. A DNA test is used by breeders.
  • Behaviour: 8.3% had a recorded behavioural disorder; 4.9% were recorded as anxious or distressed, and 1.9% as aggressive.
  • Cherry eye and hypothyroidism: neither appears among the beagle findings in the paper. That doesn't mean they never occur. It means they are not among the common problems in this population, so check what your own dog's signs actually are before assuming.
  • Disc disease (IVDD): the paper doesn't report it for beagles, but the WSAVA notes beagles are a chondrodystrophic breed with a disc-disease risk gene that is fixed in the breed. Keeping weight down and avoiding repeated jumping from furniture are the practical takeaways.
  • SRMA ("beagle pain syndrome"): an immune-mediated inflammation of the membranes around the spinal cord and brain, most often seen in young dogs between about 6 and 18 months. Signs include severe neck pain, a stiff gait, and fever. It responds well to steroid treatment when caught early, so a young beagle with sudden neck pain needs a vet quickly.

Two inherited conditions in the WSAVA profile have DNA tests that responsible breeders can use: Musladin-Lueke syndrome and Imerslund-Gräsbeck syndrome. If you're buying a puppy, ask the breeder which tests were done.

What dogs die of

For the 296 dogs whose deaths had a recorded cause, the most common causes were cancer (19.3%), a lump or mass (13.2%), and poor quality of life (12.8%), followed by brain disorders and kidney disorders (6.8% each). We cover lifespan in how long do beagles live.

A practical checklist

Brushing a beagle's teeth with a dog toothbrush
  1. Weigh monthly. Ask your vet for a body condition score and use it as your target.
  2. Brush teeth daily or as close as you can manage.
  3. Check ears weekly for odour, redness, or discharge.
  4. Trim nails every few weeks; overgrown nails were the third most common diagnosis.
  5. Ask about anal glands if your beagle scoots or licks the area.
  6. Get any new neck pain, seizure, or sudden change in behaviour looked at promptly.

Frequently asked questions

Are beagles healthy dogs? Largely, yes. The study's authors concluded the breed's disorder profile suggests it should not be considered an extreme-conformation breed. Most of its common problems are preventable.

What is the most common health problem in beagles? Obesity, at 24.3% of the sample.

Do beagles get ear infections a lot? About 11% were diagnosed with an outer ear infection in a single year.

Are beagles prone to epilepsy? Seizure disorders affected 2.0% of the beagles in this study. Breed health sources, including the WSAVA, list epilepsy as a predisposition.
