A foxhound is a type of large hunting hound bred for strong hunting instincts, a keen sense of smell, and their bark, energy, drive, and speed. In fox hunting, the foxhound's namesake, packs of foxhounds track quarry, followed—usually on horseback—by the hunters, sometimes for several miles at a stretch; moreover, foxhounds also sometimes guard sheep and houses.
There are different breeds of foxhound, each having slightly different characteristics and appearances, and each often called simply Foxhound in their native countries:
The American Masters of Foxhounds Association recognizes these breeds of foxhounds: American, Penn-Marydel, English, and crossbred foxhounds. The International Foxhound Association was created in 2012 for the international promotion of the Foxhound as a breed
Foxhounds are medium-large dogs and males typically weigh 29-32 kg (65-70 lb) and females 27-29 kg (60-65 lb). Height for males measures 55-63 cm (22-25 in) and females 53-60 cm (21-24 in). Foxhounds have a short coat, and long, strong legs, as well as deep chests for lots of lung space.
Foxhounds generally display a gentle and affectionate temperament. Foxhounds are highly active and energetic, and therefore require activity and exercise. Foxhounds are sociable and these dogs have great stamina, sense of smell, and enjoy being in a pack, as they are bred for hunting in packs.
In fox hunting, the foxhound's namesake, packs of foxhounds track and chase fox while hunters follow along on horseback. Fox hunting has shifted over the years and may differ depending on the country. Some changes over time include focusing on chasing rather than killing, and chasing other creatures, such as the coyote, instead of only the fox.
Most common causes of death among Foxhound puppies are respiratory disease, anorexia and dehydration, skin disorders, gastrointestinal disease, and myocardial infarction (heart attack). 
A kennel of working, hunting English Foxhounds in the south of England, had an outbreak of tuberculosis (TB) that impacted 180 dogs in late 2016 and early 2017. The kennel housed Foxhound puppies to adults, up to 8 years old. The Foxhounds work among six counties and some of the six counties are in the "Edge Area" that is impacted by bovine tuberculosis.
An investigation occurred which consisted of testing the dogs and looking deeper into the regional area, diet of the dogs, and even more factors while conducting tests and gathering information. The dogs eat raw meat and there was speculation about the diet containing the M. bovis that causes TB as the meat comes from areas impacted by M. bovis. 
In 2005, the American Kennel Club reported that the English and American Foxhounds were their least and fourth least registered breeds in North America with 22 and 44 registrations, respectively; the top registered breed, the Labrador Retriever, had 137,867 registrations during the same year.
