He appeared in the High Court this month to inform Justice Simon Moore whether or not he managed to obtain legal representation.
Puru said the Legal Aid Agency declined to fund his appeal because the maximum penalties for the charges he pleaded guilty to in the District Court were not imprisonment.
Justice Moore asked what remedies Puru were seeking from the High Court given the fact his dog had already been destroyed.
"This court, on an appeal of this sort, has very little it can do. The remedies are just about nothing," he told Puru.
The dog owner replied he felt there was no need for Paco to be destroyed.
Puru said an order for Paco's destruction was made despite him highlighting important issues to Judge Doherty, including claims a witness for the Whangarei District Council, lied.
"My point is I don't think I've been treated fairly," Puru said.
Justice Moore set down one hour for Puru's appeal to be heard on June 6.
