Brachycephalic Airway Obstruction Syndrome
Brachycephalic obstructive airway syndrome (BOAS), also known as brachycephalic airway obstructive syndrome (BAOS), brachycephalic airway syndrome (BAS), and brachycephalic syndrome (BS), is a pathological condition affecting short nosed dogs and cats which can lead to severe respiratory distress. There are four different anatomical abnormalities that contribute to the disease, all of which occur more commonly in brachycephalic breeds: an elongated soft palate, stenotic nares, a hypoplastic trachea, and everted laryngeal saccules (a condition which occurs secondary to the other abnormalities). Because all of these components make it more difficult to breathe in situations of exercise, stress, or heat, an animal with these abnormalities may be unable to take deep or fast enough breaths to blow off carbon dioxide. This leads to distress and further increases respiratory rate and heart rate, creating a vicious cycle that can quickly lead to a life-threatening situation. Brachyceph ...

Bulldog Portrait Frank
The Bulldog is a British list of dog breeds, breed of dog of mastiff type. It may also be known as the English Bulldog or British Bulldog. It is a stocky, muscular dog of medium size, with a large head, thick folds of skin around the face and shoulders and a relatively flat face with a protruding lower jaw. Selective breeding for appearance has led to increased susceptibility to health problems including Brachycephalic airway obstructive syndrome, brachycephaly, Hip dysplasia (canine), hip dysplasia, heat sensitivity and skin infections. The dogs may not be bred in Norway or the Netherlands, because of concerns about their quality of life. The modern Bulldog was bred as a companion dog from the Old English Bulldog, a now-extinct breed used for bull-baiting until that was outlawed under the Cruelty to Animals Act 1835, Cruelty to Animals Act of 1835. The Bulldog Club (in England) was formed in 1878, and the Bulldog Club of America was formed in 1890. While often used as a symbo ...

Hyperplasia
Hyperplasia (from ancient Greek ὑπέρ ''huper'' 'over' + πλάσις ''plasis'' 'formation'), or hypergenesis, is an enlargement of an organ or tissue caused by an increase in the amount of Tissue (biology), organic tissue that results from cell proliferation. It may lead to the Gross anatomy, gross enlargement of an organ, and the term is sometimes confused with benign neoplasia or benign tumor. Hyperplasia is a common preneoplastic response to stimulus. Microscopically, cells resemble normal cells but are increased in numbers. Sometimes cells may also be increased in size (hypertrophy). Hyperplasia is different from hypertrophy in that the Cellular adaptation, adaptive cell change in hypertrophy is an increase in the cell size, ''size'' of cells, whereas hyperplasia involves an increase in the ''number'' of cells. Causes Hyperplasia may be due to any number of causes, including proliferation of basal layer of epidermis to compensate skin loss, Chronic inflammation, chr ...
