From dachshunds to labradors and poodles to pomeranians, dogs of all sizes have pounded the pavement across the state for the annual RSPCA Million Paws Walk.

Brisbane's South Bank was wagging with excitement as 3,000 owners and their four-legged friends gathered for a doggie "playdate" to remember, while raising funds for the animal charity.

Some dogs came "as is" for the occasion, while others aimed to impress with costumes and outfits.

Marshmellow and Bubblegum the dachshunds were among the "furry fashionistas" in the crowd.

"It's so nice being here and having some interaction for them with other dogs, although today, this one isn't interested," Candice Wynd said as she held Bubblegum.

"We come every year, it's great and this year we can bring Marshmellow too as she's only four months old."

Dog owners mingled at South Bank before heading on the walk along the Brisbane River.

Canine information booths and businesses including dog treat companies, shampooing, health and animal photography were dotted around the area containing thousands of overly excited pooches.

Malcolm Pearce and his dog Incubus were much more subdued as Million Paws Walk "veterans" taking part for the tenth year.

Mr Pearce said he was proud to show off his Australian shepherd while supporting the RSPCA.

"I just love people coming up and giving him a pat and showing them that these are fantastic and so easy to train," he said.

"This is a great event and we love being part of it all over Brisbane not just at South Bank.

"Some people don't have dogs or can't have dogs so it's a great event for them too."

Dozens of Million Paws Walk events were held across the country today, with more than 20,000 people expected to take part in Queensland alone.
