About 60 dogs took part in the event which included a range of obedience activities, including walking at heel, standing on command and completing jumps, across three levels.
Gael competed in all three levels but had been a "bit too excited", Ms Walker said.
Event co-ordinator Lyn Clearwater said it was a sport for any breed.
Pugs, miniature schnauzers, Border collies, golden retrievers, and poodles had all turned up to have a go.
The dog and handler moved from station to station completing each exercise in the sequence, while being marked by a judge.
Rally-O was a way to introduce dogs to the sport of obedience, or as a sport on its own.
