"It was his race to win and he goofed around and didn't knuckle down. It is a colt thing, taking life too casually.
"I wanted to run out on the track and give him a boot up the arse or at least a good growling, and while you can never do that, it is what I bloody well felt like doing.
"It happens sometimes but he picked a bad day to be a lazy bugger."
Dalgety says that lack of effort at the crucial moment means Krug bounced out of the race feeling good, so he joins what is a near full-strength Kiwi assault on the rich Queensland carnival.
He will be on a plane on Friday morning alongside Amazing Dream and the Ray Green-trained quartet of Copy That, American Dealer, Tommy Lincoln and Captain Nemo.
"We might contest the Redcliffe Derby but the big aims are The Rising Sun and the Queensland Derby," says Dalgety.
"Blair [Orange] will drive him in those big ones but we might use a pick-up driver if he goes to the Redcliffe Derby."
The Rising Sun is the new A$250,000 race for mainly 4-year-olds but with two 3-year-olds invited, so Krug could take on Amazing Dream and Copy That there, all three beaten Jewels favourites.
Copy That and American Dealer passed blood tests yesterday which cleared them of any viral complaints after Sunday — and are all systems go for Queensland.
"We all fly out Friday but I don't think any of mine will race there until June 26," says Green.
"The blood came back fine, so we are going to put Sunday behind us and give them their chance."
Green confirmed Copy That already has pads placed under his shoes to help with any hoof issues and he could be the big Jewels bounce back horse if able to find his favoured pacemaking role around Albion Park.
Copy That and Amazing Dream could contest the Rising Sun as well as open-class races culminating in the Blacks A Fake at Albion Park on Saturday, July 24.
Many of the other stars from Sunday's mega-meeting, such as Bettor Twist and A Bettor You and the three trotting winners, are already heading to the paddock.
