has been selectively bred for, as it allows the dog to be easily seen when its head is down following a scent. The tail does not curl over the back, but is held upright when the dog is active. The beagle has a muscular body and a medium-length, smooth, hard coat. The beagle has an even temper and gentle disposition. Described in several breed standards as 'merry', they are amiable and typically neither aggressive nor timid, although this depends on the individual. They enjoy company, and although they may initially be standoffish with strangers, they are easily won over. They make poor guard dogs for this reason, although their tendency to bark or howl when confronted with the unfamiliar makes them good watch dogs.
