One half of a couple who fell victim to 'dogfishing' will walk more than 200 miles with their successful petition in hand.
Richard Ackers, founder of the 'Justice for Reggie' campaign, will begin his journey across four days in December from his home in Wigan to Number 10 Downing Street.
Last year, he bought 12-week-old puppy, Reggie, for his partner Alicia Sherman as a Christmas present.
At first they believed they were purchasing the dog from St Helens.
However, just two days after it was brought home by its new owners, Reggie sadly died.
It is feared that little Reggie may have come from an illegal farm as the puppy became sick within 12 hours of arriving with the new family and died of parvovirus - a highly infectious disease that his owners claim would have been caught during transportation.
The couple later found out that his chip was actually registered in Dublin, which they believe could mean he was shipped to the country illegally.
Alicia, originally from Wigan, previously told the Liverpool Echo : "The night we got him it started with diarrhoea, the next day he was vomiting and just not himself.
"We rang the vets who said that’s not normal for a young Labrador puppy and when we took him for tests, they did a parvovirus test that came back positive.
"I’m a nurse and I’ve seen bad things but never someone looking that bad."
Now, Richard, a 32-year-old trainee pilot, plans to arrive at Downing Street a year on from Reggie's passing.
As the petition now has over 100,000 signatures, parliament will consider it for debate it and Richard hopes they take it seriously.
The campaign hopes to see a change in the way sellers verify themselves online and if a law comes into practice it could see potential dog sellers have to show proof of address and photo ID before their ad goes live.
As well as this it would ask for photo or video evidence of the young pups suckling on their mother in hope to get rid of fake mums being used.
He explained to TeamDogs that money raised from the walk will go help three major animal charities including Animal protection services, Hope Rescue and Almost home rescue.
Followers of the campaign are encouraged by Richard to join him on the steps of Number 10 to show their support.
Richard added: “We truly hope you would consider attending and be a part of this incredible journey to end the misery these animals endure, and to create change in the law on the way animals are sold on websites.”
