Noel, you can look up the race careers of all Australian greyhounds on GRV (go to E-Form and put in the name of the dog). Apart from the brief summary at the top it will bring up a complete list of a dog's performances. Of course the relevant database has not been around forever but it will be get you back a couple of decades or thereabouts. As a matter of interest, from where are you sourcing your information. If it is the Greyhound-data site then I would not be taking much notice of any given dog's performances as reflected in the site. My impression is that the race performance information is very inadequate.
Also as a matter of interest and apologies in advance if you have already told us in previous posts but do you have a winter recess. It only got to 18 degrees Celcius here yesterday and I felt quite cold. If I had a dog down the backyard then I think I would have at least considered rugging it, especially after the 40 plus degree temps we have had recently. I am thinking it may not have got past 10 degrees there.
