Pneumonia in Dogs
-
Most lung tissue is made up of tiny clusters of air “balloons” (called alveoli). Each balloon is lined by a thin layer of cells and surrounded by a network of very small blood vessels. When you breathe in, air fills the balloons. The cells in the lining and the small blood vessels exchange oxygen from the air for carbon dioxide, which you then breathe out. The main pathway from the lungs to the outside of the body consists of the trachea (the large airway that begins at the back of the throat and continues down into the lungs) and the nostrils.

As a result, pregnancy in cats tends to be seasonal, with most births occurring from spring through early fall.

Pregnancy is the time between conception and birth when puppies develop and grow inside the mother’s uterus. By day 40, the fetus has eyelids, claws, and hair, and the gender is apparent. While toy breeds tend to have smaller litters of one to four puppies, larger breeds may carry as many as eight to 12 puppies. After 56 and 70 days, or about 2 months, puppies are ready to be born.

-
Heartworm disease is serious and potentially fatal. It affects dogs, cats, and up to 30 other species of mammals. Heartworm disease has been reported in all 50 states. It is caused by parasitic worms (heartworms) living in the major vessels of the lungs and, occasionally, in the heart. Heartworms are transmitted (as microscopic larvae) through the bite of an infected mosquito. The scientific name for the heartworm parasite is Dirofilaria immitis.
