Australian Cattle Dog: The dog who holds the Guinness record for longest life span was an Australian Cattle Dog named Bluey, who lived to be 29 years old. Thatâs astounding. I donât know of any ACDs who have approached that record, but I do know this breed can live a good 12 to 15 years, sometimes longer.
Diabetes Mellitus is a major risk factor for Peripheral Arterial Disease. A leg turning black and cold may be a sign of severe arterial insufficiency resulting on gangrene. Also, another condition called Venous Insufficiency may cause the leg to turn dark red or bluish when the person is in a sitting or standing position. Gangrene.
Bubonic plague is fatal (though there is now a cure) and leads to an infection of the lymph nodes, which become swollen (bubo is Latin for bump). Here's what actually happens. The bacteria grow inside the flea, causing conditions which block the insect's stomach and induce extreme hunger. The flea starts to feed on a host, and in this way the disease spreads. Boccaccio, Plutarch and Chaucer all mention the Black Death in their literary works. The disease made short life spans even shorter.
