RATTLIN GOLDSTAR and Razldazl Will renew rivalry in the second round of the Comerford Cakes National Puppy Stake at Shelbourne Park this evening.

THE COMERFORD Cakes National Puppy Stake ranks very high on my list of favourite greyhound stakes of the entire year but even allowing for that, this year’s renewal has a scent of the old adage that too much of a good thing is a bad thing.
