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 !!!!

Last year the Wheeling Island Racetrack and The Ohio State University  formed a joint venture targeting the wellness of greyhounds.

With support of the West Virginia Racing Commission and Wheeling Island, the investigative study was conducted in July (2011) at Wheeling by Dr. Couto, Dr. Bohenko and a group of veterinarians and students from Ohio State University.


Dr. Bohenko said the study had three goals –
provide health screens for 120 greyhounds,
test for tick borne and heart worm diseases and
the effects of exercise (racing) on blood work.

“Through this joint effort, we are trying to learn more about these greyhounds and what makes them tick,” Dr. Bohenko said. “This is the first time a study of this magnitude using actively racing dogs has ever been conducted. Mostly retired greyhounds have been used in the past.”

The greyhounds in the study had blood drawn on three occasions – the day before they were scheduled to race, immediately after their race and one to two hours after the completion of their race.

In addition to tests for heart worm and tick borne diseases, Dr. Couto and his staff did complete blood counts (CBCs), serum chemistry profiles (liver, kidney function, etc.) and blood gas analysis (BGs). The heart worm and tick borne disease tests all were negative.

“It’s a good reflection on the care these greyhounds receive,” Dr. Bohenko said. “It also points out to people who want to adopt them that there are no problems.”
