When raised with the proper training and socialization, the American Pit Bull Terrier makes an excellent companion for children. He is loving and gentle with people and often makes a lousy guard dog because of his tail-wagging eagerness to greet the person at the door.
Asthma. Asthma is a chronic inflammatory disease of the airways. The disease manifests as recurrent attacks of wheezing, coughing and shortness of breath. During an asthma attack, the muscles surrounding the airways contract, limiting the amount of air supply to the lungs. The lack of sufficient air supply results in a choking sensation.
In an asthma attack, the air passages of the lungs, known as bronchi, overreact to substances that are ordinarily harmless. Cells in the airways known as mast cells release histamines and leukotrienes, which induce inflammation.These substances prompt the smooth muscles of the airways to go into spasm and constrict.sthma is a condition in which the airways of the lungs narrow in response to environmental triggers (pollens, dust, animal dander, smoke), cold air, exercise, respiratory infection, or emotional distress. Some people suffer asthma attacks as an allergic response to various airborne environmental triggers.
