Beagle

Health
The median longevity of Beagles is 12.35 years, which is a typical lifespan for a dog of their size.

Beagles may be prone to epilepsy, but this can be controlled with medication. Hypothyroidism and a number of types of dwarfism occur in Beagles. Two conditions in particular are unique to the breed: Funny Puppy, in which the puppy is slow to develop and eventually develops weak legs, a crooked back and although normally healthy, is prone to range of illnesses; Hip dysplasia, common in Harriers and in some larger breeds, is rarely considered a problem in Beagles. Beagles are considered a chondrodystrophic breed, meaning that they are prone to types of disk diseases.

In rare cases, Beagles may develop immune mediated polygenic arthritis (where the immune system attacks the joints) even at a young age. The symptoms can sometimes be relieved by steroid treatments.

Their long floppy ears can mean that the inner ear does not receive a substantial air flow or that moist air becomes trapped, and this can lead to ear infections. Beagles may also be affected by a range of eye problems; two common ophthalmic conditions in Beagles are glaucoma and corneal dystrophy. "Cherry eye", a prolapse of the gland of the third eyelid, and distichiasis, a condition in which eyelashes grow into the eye causing irritation, sometimes exist; both these conditions can be corrected with surgery. They can suffer from several types of retinal atrophy. Failure of the nasolacrimal drainage system can cause dry eye or leakage of tears onto the face.

As field dogs they are prone to minor injuries such as cuts and sprains, and, if inactive, obesity is a common problem as they will eat whenever food is available and rely on their owners to regulate their weight. When working or running free they are also likely to pick up parasites such as fleas, ticks, harvest mites and tapeworms, and irritants such as grass seeds can become trapped in their eyes, soft ears or paws.

Beagles may exhibit a behaviour known as reverse sneezing, in which they sound as if they are choking or gasping for breath, but are actually drawing air in through the mouth and nose. The exact cause of this behaviour is not known, but it is not harmful to the dog.

Working life

Hunting
Beagles were developed primarily for hunting hare, an activity known as beagling. They were seen as ideal hunting companions for the elderly who could follow on horseback without exerting themselves, for young hunters who could keep up with them on ponies, and for the poorer hunters who could not afford to maintain a stable of good hunting horses. Before the advent of the fashion for foxhunting in the 19th century, hunting was an all day event where the enjoyment was derived from the chase rather than the kill. In this setting the tiny Beagle was well matched to the hare, as unlike Harriers they would not quickly finish the hunt, but because of their excellent scent-tracking skills and stamina they were almost guaranteed to eventually catch the hare. The Beagle packs would run closely together ("so close that they might be covered with a sheet") which was useful in a long hunt, as it prevented stray dogs from obscuring the trail. In thick undergrowth they were also preferred to spaniels when hunting pheasant.

With the fashion for faster hunts, the Beagle fell out of favour for chasing hare, but was still employed for rabbit hunting. In Anecdotes of Dogs, Jesse says:

In rabbit-shooting, in gorse and thick cover, nothing can be more cheerful than the beagle; and they have been called rabbit-beagles from this employment, for which they are peculiarly qualified, especially those dogs which are somewhat wire-haired.
In the United States they appear to have been employed chiefly for hunting rabbits from the earliest imports. Hunting hare with Beagles became popular again in Britain in the mid-19th century and continued until it was made illegal in Scotland by the Protection of Wild Mammals (Scotland) Act 2002 and in England and Wales by the Hunting Act 2004. Under this legislation Beagles may still pursue rabbits with the landowner's permission. Drag hunting is popular where hunting is no longer permitted or for those owners who do not wish to participate in blood sports but still wish to exercise their dog's innate skills.

The traditional foot pack consists of up to 70 Beagles, marshalled by a Huntsman who directs the pack and who is assisted by a variable number of whippers-in whose job is to return straying hounds to the pack. The Master of the Hunt is in overall day-to-day charge of the pack, and may or may not take on the role of Huntsman on the day of the hunt. Beagles may also be employed individually or in a brace (a pair).

As hunting with Beagles was seen as ideal for young people, many of the British public schools traditionally maintained Beagle packs. Protests were lodged against Eton's use of Beagles for hunting as early as 1902 but the pack is still in existence today, and a pack used by Imperial College in Wye, Kent was stolen by the Animal Liberation Front in 2001. School and university packs are still maintained by Eton, Marlborough, Wye, Radley, the Royal Agricultural College and Christ Church, Oxford.

Beagles have been used for hunting a wide range of game including Snowshoe Hare, Cottontail rabbits, game birds, Roe Deer, Red Deer, Bobcat, Coyote, Wild Boar and foxes, and have even been recorded as being used to hunt Stoat. In most of these cases, the Beagle is employed as a gun dog, flushing game for hunter's guns.

Quarantine
Beagles are used as detection dogs in the Beagle Brigade of the United States Department of Agriculture. These dogs are used to detect food items in luggage being taken into the United States. After trialling several breeds, Beagles were chosen because they are relatively small and unintimidating for people who are uncomfortable around dogs, easy to care for, intelligent and work well for rewards. They are also used for this purpose in a number of other countries including by the Ministry of Agriculture and Forestry in New Zealand, the Australian Quarantine and Inspection Service, and in Canada, Japan and the People's Republic of China. Larger breeds are generally used for detection of explosives as this often involves climbing over luggage and on large conveyor belts, work for which the smaller Beagle is not suited.
