The October 25 event involves a 10km walk around the river to raise funds for the dog rescue voluntary organisation.
Dog walkers will meet at Victoria Park foreshore, Taylor Reserve, from 9am onwards to complete the circuit by 1.30pm.
Haven volunteers invite walkers to collect dogs from the refuge and return them after the event, or bring their own dogs.
