Apperance: The general appearance of the Beagle resembles a Foxhound in miniature, but the head is broader and the muzzle shorter, the expression completely different and the legs shorter in proportion to the body.They are generally between 33 and 41 cm (13 and 16 inches) high at the withers and weigh between 8 and 16 kg (18 and 35 lb), with bitches being slightly smaller on average.
They have a smooth, somewhat domed skull with a medium-length, square-cut muzzle and a black (or occasionally liver), gumdrop nose. The jaw is strong and the teeth scissor together with the upper teeth fitting perfectly over the lower teeth and both sets aligned square to the jaw. The eyes are large, hazel or brown, with a mild hound-like pleading look. The large ears are long, soft and low-set, turning towards the cheeks slightly and rounded at the tips. Beagles have a strong, medium-length neck (which is long enough for them to easily bend to the ground to pick up a scent), with little folding in the skin but some evidence of a dewlap; a broad chest narrowing to a tapered abdomen and waist and a short, slightly curved tail tipped with white. The white tip, known as the "stern" or "flag" 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 front legs are straight and carried under the body while the rear legs are muscular and well bent at the stifles.
Colouring: Beagles appear in a range of colours. Although the tricolour (white with large black areas and light brown shading) is the most common, Beagles can occur in any hound colour. Tricoloured dogs occur in a number of shades, from the "Classic Tri" with a jet black saddle to the "Faded Tri" where the faint black markings are toned with brown. Some tricoloured dogs have a broken pattern, sometimes referred to as pied. These dogs have mostly white coats with patches of black and brown hair. Two-colour varieties always have a white base colour with areas of the second colour. Tan and white is the most common two-colour variety, but there is a wide range of other colours including lemon, a very light tan; red, a reddish, almost orange, brown; and liver, a darker brown. Liver is not common and is not permitted in some standards; it tends to occur with yellow eyes. Ticked or mottled varieties may be either white or black with different coloured flecks (ticking), such as the blue-mottled or bluetick Beagle, which has spots that appear to be a midnight-blue colour, similar to the colouring of the Bluetick Coonhound. Some tricolour Beagles also have ticking of various colours in their white areas.
Tricolour Beagles are almost always born black and white, with the brownish areas developing later. The brown may take between one and two years to fully develop. Some Beagles gradually change colour during their lives.
The Beagle has an even temper and gentle disposition. Described in several breed standards as "merry" they are amiable and not generally aggressive or timid. They enjoy company, and although they may initially be stand-offish with strangers they are easily won over. They make poor guard dogs for this reason, although their tendency to give bark or howl when confronted with the unfamiliar makes them good watch dogs; in a 1985 study conducted by Ben and Lynette Hart the Beagle was given the highest excitability rating along with the Yorkshire Terrier, Cairn Terrier, Miniature Schnauzer, West Highland White Terrier and Fox Terrier. Beagles are intelligent, but as a result of being bred for the long chase are single-minded and determined, which can make them hard to train. They are generally obedient but can be difficult to recall once they have picked up a scent and are easily distracted by smells around them. They do not generally feature in obedience trials; while they are alert, respond well to food-reward training, and are eager to please, they are easily bored or distracted.
Beagles are excellent with children and this is one of the reasons they have become popular family pets, but they are pack animals, and can be prone to separation anxiety. 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 other dogs, but can be excitable and may bay. They are not 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, though regular exercise helps ward off the weight gain to which the breed is prone.
The median longevity of Beagles is about 12.3 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; and Chinese Beagle Syndrome in which the eyes are slanted and the outer toes are underdeveloped but otherwise development is as normal. Hip dysplasia, common in Harriers and in some larger breeds, is rarely considered a problem in Beagles.
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. They are prone to "cherry eye", an inflammation of the third eyelid, and sometimes their lashes grow into the eye causing irritation, a condition known as distichiasis; both these conditions can be corrected with surgery. They can suffer with glaucoma, and 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, ears or paws.
Beagles may exhibit a behaviour know 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.
