Jamie Thorne from JST Photography will volunteer her expertise to take portraits of people with their pets.

Money raised from the portraits will go to the Central West Animal Rescue.

In addition to animal portraiture, the family event will include a barbecue, a best-dressed Christmas pet competition and apple bobbing for dogs.

Organiser Jasmine Smart invited everyone to come along to the park besides the Robin Hood Hotel, even those people who don't own pets.

"Come and have some fun. It's a massive area so throw a ball with your dog and socialise," she said.

Santa Paws in the Park will run from 9-3pm.

Pet portraits are $20 for a 4x4 print and the digital copy.

All of the money raised will go towards helping rehome the Central West Animal Rescue foster pets.
