Pip, aged five, lives with Hunstanton RNLI crew members Louise and Clare Kyle.
Inshore lifeboat crew member Louise and mum Clare, who's a head launcher and plant driver at the station decided to put his twice-daily walks towards a good cause.
'He loves his walks, he loves going down the beach for a swim,' said Louise. 'But he also loves his food. He eats anything and anything, which is why he's a little on the tubby side.'
She added while Pip currently weighs in at almost 14kg, against a recommended maximum of 9kg for his breed, the challenge is going well, with 29 miles already in the bank with almost two weeks to go.
This year's Mayday Mile has so far raised almost £250,000, with more than 3,000 entrants clocking up around 40,000 miles between them.
On Saturday 31 May, he'll be walking along the Prom in Hunstanton from the Ski Club to the lifeboat station via the town's High Street.
'He might get a treat afterwards,' said Louise. 'Just the one, mind you - he is trying to lose weight.'
Notes to Editors
Louise and her mum Clare volunteer at Hunstanton RNLI.
The station operates both the inshore lifeboat Spirit of West Norfolk and search and rescue hovercraft
Hunstanton Flyer.
Like those at more than 200 RNLI stations around the coast of the UK and Ireland, their work would not be possible without the kindness of those who donate to the charity that saves lives at sea.

Pip is hoping to shed some ballast, as well as raise funds for the RNLI
The RNLI is the charity that saves lives at sea. Its volunteers provide a 24-hour search and rescue service around the United Kingdom and Republic of Ireland coasts. The RNLI operates 238 lifeboat stations in the UK and Ireland and more than 240 lifeguard units on beaches around the UK and Channel Islands. The RNLI is independent of Coastguard and government and depends on voluntary donations and legacies to maintain its rescue service. Since the RNLI was founded in 1824, its lifeboat crews and lifeguards have saved over 146,700 lives.
