Parker had already developed a healthy opinion of Paulie Walnuts before the son of Fernando Bale had made his racetrack debut.
“When he had his first trial over 380 (metres) he went 21.78 and we said ‘OK this fella is pretty handy’," he said.
“His slips were decent as well but you just don’t know how they’ll go in a field.
“Having speed is one thing but they have to be a race dog.
“If you have speed and a race dog, you know you have a handy one.
“He hasn’t proven himself 100% that he’s a race dog, but we’ll see.”
Parker is, however, buoyed by a hint from champion trainer Tony Brett that he’d be willing to make some room in his kennel for a greyhound like Paulie Walnuts.
“We’ve been staying with Tony and he’s been really good and very helpful,” Parker said.
“Tony tends to make room for the good ones, but I would like to hold onto (Paulie Walnuts) for as long as I can. More to prove to myself that I can get him going.”
Parker, who is in-charge of an 18-strong kennel, said there was plenty of options closer to home for Paulie Walnuts throughout the year.
“There’s obviously the Young Guns and the Cup, but that’s still a long way away,” he said.
“We could also have a look at the Rocky Cup but then I look at the dogs in Tony (Brett’s) kennel and think ‘we’re probably going to be racing them’.
“We’ll take it one race at a time. One little slip-up can bring everything undone. You need to a look ahead but you can’t lock anything in.”
Parker also has Jackie Chiles lining up in Race 9 at Albion Park on Monday.
