Beagles, those ancient hunters selected for their wonderful sense of smell and robustness, also have their weaknesses. In this article, you’ll find out about the most common diseases in beagles.

Many of these illnesses are common to all dogs, but slightly more prevalent in this breed. First of all, we’re going to give you a brief overview of the beagle’s traits, a dog as sociable and intelligent as it is beautiful. Don’t miss it.

What are beagles like?

Known for their use in hunting and animal testing, beagles have actually won people over for other reasons. One of them is their sociable character and great energy, in addition to their general lack of congenital disorders.

Another reason is that they’re very intelligent dogs, enjoy company a lot, and aren’t aggressive at all. Despite their obedience, it can be a little difficult to get them to focus on the keeper’s indications, especially if they’re on a track.

That leads us to the next point: along with the St. Hubert Hound (or Bloodhound), it’s one of the dogs with the best sense of smell in the canine kingdom. The morphology of its muzzle helps catch any odors near its nose, so these dogs are better at following traces on the ground rather than in the air.

Beagles have a life expectancy of about 15 years, according to their medium size. They tend to get along well with children, hence their popularity in homes as a family member. But careful, each animal has its own personality.

Which are the most common diseases in beagles?

This breed doesn’t have important congenital diseases, in fact most of them are due to the traits of its morphology. In any case, here are the most common ones that you’ll find.

1. Epilepsy

An epileptic seizure is defined as a brain attack resulting from an excessive neuronal discharge that manifests itself as convulsions, hyperthermia, excessive salivation, rhythmic blinking, or facial contractions, among other signs. This condition is easily controlled with medication such as phenobarbital or bromide potassium.

2. Hypothyroidism: one of the most common diseases in beagles

This is one of the most common endocrine diseases in dogs, and beagles are no exceptions. Due to their tendency to gain weight from the disease, a correct diagnosis is important. Hypothyroidism is characterized by a tendency to gain weight, hypothermia, and a number of skin conditions.

Among the most common are hair loss, color changes, alopecia, predisposition to skin infections and, rarely, abnormalities of the nervous and reproductive systems. The cause of this disease is the deficient activity of the thyroid hormones, which in turn, causes a drop in metabolism.

3. Ear diseases

The long, drooping ears of this breed are often an impediment to proper ear ventilation, so these dogs tend to get ear infections. If you see your dog’s head tilted, if it scratches, has a warm ear, or complains when you touch it, you may need to visit the vet to check that everything is okay.

4. Eye diseases

It’s true that, despite their robustness, the beagles are one of the breeds that can present eye problems. Here are the most common:

  • Glaucoma: Glaucoma is the increase of the intraocular pressure by an excessive production of the aqueous humor, the liquid that fills the eye. It’s a serious disease and, if left untreated, can lead to blindness.
  • Corneal dystrophy: Usually manifests itself as white opacity in the cornea or part of it, and can be painful. Monitoring and treatment are necessary to prevent ulcers from appearing, as sight loss is normally mild.
  • Distichiasis: This disease appears when the dog develops two rows of eyelashes and one of them grows towards the eye or in a disordered fashion, which may lead to eye irritation and even infection.
  • Cherry eye: When the third eyelid gets weak, the tear gland can prolapse and stick out of the eye, which gives the name to this illness. The most common treatment is surgery because it can lead to infection.
