Registration for the fundraising walk is a gold coin donation and all proceeds will go towards the nine bronze statues - Hairy Maclary and his eight bronze friends.
People are encouraged to "bring your dog, dress up as your favourite Hairy Maclary character - or just join in all the fun!".
A sausage sizzle for the people and special sausages and water bowls for the dogs will be at the finish line for everyone involved, along with storytelling and a few surprises.
