An article by Bruce Teague in the Australian Greyhound magazine
I will only quote snippets as its a 4 page article
Over-simplyfying things, greyhound racing is becoming more of a production line now.
Todays punters might look, not just at what the dogs history shows, but also how often it has been racing.
In practice many dogs are racing twice weekly for weeks on end
Recently, I started a closer look at WPK in particular, as well as around the Victorian circuit, quite a few dogs can be seen backing up within a 48 hour period
After converting all the runs to times over the WPK 525M, which my computer happily does for me, I checked the difference.
About 40% actually ran better time in the second race, but only by a couple of lengths on average
The 60% which ran worse time did so by an average margin of 7 lengths
In the end the result is pretty clear cut- the majority of dogs dont do as well when they have to make a second effort within 2 days
Top QLD trainer Tony Zammit, has said he prefers never to run his dogs more than once weekly.
Prominent vet John Kohnke , tells us that "generally, the dog should not be galloped for the full distance during the week or so leading up to a race, and only given sMALl slips over 150m or so, finishing within 2 days of a race."
Backing up within a 48 hour period can be a very risky proposition

MT79/MAL have been saying this repeatedly on SAFOOTY
Risk dogs that back up if less than 4 days since thier previous runs
