A breed with high energy, the Beagle can be a poor listener and it can be very difficult for new owners. When poorly trained they can be very dangerous while protecting their owners or property. Beagles are prone to barking and can be very noisy, as they are known to be leery of an unfamiliar scent. Beagles can have weight issues if they do not get enough exercise which can make things difficult. For a new dog owner with a tight schedule or no commitment, this is not your ideal breed.
