“But, this particular fellow, he broke in very good.
“He is just getting better and better but he is still green as a dog in the mind so we are taking our time – there is no rush.
"The truth is Bill and I still don't know what we've got. The record run the other night was just his third ever 520 metre run so as good as we knew he was, it was still a big surprise.
"We are nowhere near the bottom of him yet which is as scary as it is exciting."
Following the boom dog's trip to Brisbane, the Silver Chief and National Derby in Sydney are likely to be on his agenda.
While Dalwhinnie is breaking records now over 520 metres, Butler thinks there is more of the same on the horizon – just over a further trip once the dog matures with more racing.
“Not trying to get too far ahead of myself, but I will make a big call and I think the dog is going to destroy records over 600 metres,” the trainer said.
“I really do. I can't see how he won’t.
“That was his third 500 metre run the other night and the way that he came home – he is just a machine.
“I am really looking forward to him getting out to 600 metres, once he gets over that trip he will go really, really well.”
