The Beagle will let you know he's around, especially if left alone with no companions (you may need to get two). The beagle has a LOUD voice! They can be stubborn and difficult to train. Because of their deep instinctive natures beagles should not be left to roam alone. Their nose and need for activity may lead them into troublesome situations. Beagles are gentle animals who are great with children and other dogs.
