It is important to watch your beagle because they tend to loose focus while tracking with their noses to the ground. They are fairly clean and don't require frequent baths. In addition, if these dogs are properly socialized, they bond well to family members, and especially to children. Few beagles will act aggressively towards strange people or dogs once introduced, especially when well socialized. Beagles love to spend time with their family, and are happiest when they can.
Epilepsy is fairly prevalent in beagles as well, often times causing seizures.
They must be watched very carefully if not leashed while outdoors because they roam. Sometimes hard to train, especially housetrain. Many beagles need constant obedience sessions until they are two years old. Beagles will bark and howl quite a bit, specifically when they are left alone. Beagles may be difficult to train due to their active nature.
