Strutt Your Mutt will be held at the East Point Pavillion and Royal Green on Sunday, April 30.
Previous canine-filled fun events had been held at the nearby Benacre Estate.
The Strutt Your Mutt charity day is hosted by Wangford Veterinary Clinic.
They say thousands of dogs, owners and local pet-focused businesses from all over the area will “come together to celebrate the relationship people share with dogs”.
Activities include a fun dog show, fastest recall, dog yoga, a breeds parade, My Dog’s Got Talent and a pet-themed auction
In addition there will be a selection of local crafts, pet-related trade and charity stalls for peruse, all while enjoying sea shanties from the Lowestoft Longshoremen.
This year, the benefitting charities will be Hearing Dogs for Deaf People and the Suffolk Lowland Search and Rescue Team.
A spokesman for the Lowestoft event said: “This unmissable event is packed with exciting activities for your dog, fun, information and shopping for you.
“The aim of the event is a simple one – to bring the dog loving community together for a fantastic, fun-filled day, to meet others who share the same love and respect for dogs and raise funds for these two very worthwhile charities.”
Event entry is free but there will be a collection bucket for people to make a donation.
In return, people will receive a rosette for their dog to say thank you.
There will also be a donation point for donations of cat and dog food.
Over the last 12 years the event has raised more than £60,000 and made donations to Hounds for Heroes, Dogs for the Disabled, Hearing Dogs for Deaf People and other service dog charities.
