A greyhound draws in 60-90 liters of air in 50-90 breaths in a 30-second gallop, extracting 1500 mLs of oxygen from the air to metabolize the energy in its muscles.
During the gallop, the blood pressure in the lung arteries increases from 7 mm mercury pressure units at rest, to 40 units at the gallop, similar to the pressure peak in a human athlete, but only one third of the maximum pressure in a racehorse’s lung artery, which reaches 120 mm mercury pressure, or roughly 2.1 psi of pressure.
A greyhound produces around 100Kcals or 100,000 watts of waste heat energy during a 30 second race, sufficient to bring 600mL of tap water to the boil in around 2 minutes.
After a race, the gut function is restored over a 30 minute period to digest food, but the immune system is depressed for 30-120 minutes after a hard gallop.
Loading stress placed on the limb bones is repaired over a 7-10 day period after a race.
What a dog !!!!

How big is your Greyhounds BRAIN …

In Helmut Hemmer’s Domestication: The Decline of Environmental Appreciation (1990) ,is a very good discussion of relative brain sizes in different types of wolves and a different types of domestic dog. In relative terms, not all dogs have smaller brains than wolves.

Hemmer points out that the largest brains are in northern Eurasian wolves. Northern North American wolves have slightly smaller brains, but southern wolves have brains that are 5 to 10 percent smaller than the northern wolves.

Dingoes, which are feral dogs, have brains that are 25 percent smaller than northern wolves. Dogs from the tropics and East Asia have brains that are 15 to 2o percent smaller than those of dingoes. Improved Western breeds have brains that vary between those of the dingo and the East Asian and tropical primitive breeds, and some Western breeds, including the greyhounds and “some watchdog breeds” have brains that are proportionally the same size as southern wolves.

Hemmer then goes on to explain that brain size in European dogs was small from the Neolithic to the Middle Ages, and then, as the Middle Ages came about, Europeans began to breed improved dog stocks. Hemmer implies that this is why Western breeds have had an increase in brain size since then.

It is often said that domestication has resulted in smaller brains in domestic dogs. It’s actually much more complex than that.
