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.

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.
Feet turn black in peripheral gangrenous changes, in diseases of arteries which lack to supply blood distally, due to insufficiency.e.g.DIABETIC FOOT . Feet turn blue in Peripheral cyanosis, in cardiovascular diseases , especially in children,in arterial insufficiency to regulate oxygenated blood to the distal extrimities. E.g. TETRAD OF FALLOT.
