Not all beagles will howl, but most will bark when confronted with strange situations, and some will bay (also referred to as 'speaking', 'giving tongue', or 'opening') when they catch the scent of potential quarry. They also generally get along well with cats and other dogs. They are not too demanding with regard to exercise; their inbred stamina means they do not easily tire when exercised, but they also do not need to be worked to exhaustion before they will rest. Regular exercise helps ward off the weight gain to which the breed is prone.
