The Pet Day - which will be held on February 2 - will involve demonstrations with animal behaviourists, the SPCA education team, and Air Force dogs.
It will also feature craft activities, costume competitions, and a mobile SPCA adoption centre.
The decision to allow animals to come along for the day was an easy one, Hodson said.
"All our team here has animals ourselves. We're all a bit animal-crazy."
Though all animals must be socialised and properly restrained, there are no other limitations, she said.
"We're expecting mainly dogs, but we wouldn't be surprised if people brought other animals."
The event is gold coin entry, all of which will go towards the SPCA.
The Mates & Mascots exhibition, although free, already fundraises for the SPCA by selling guide books in exchange for a donation.
Mates & Mascots, which has been running since December 15, ends on February 17.
