Earlier this month six-year-old Finn got a tour around the local fire station (number 29), and last month he went apple picking (number 49).
Other adventures Finn has experienced include meeting a celebrity (number 39) and going on TV (number 24) - which were both completed in one day when a local news crew came to film Finn meeting Waffle Nugget from The Dogist.
The pooch also got to have a beer with his owners (number 47).
Writing on their GoFundMe page, Finn's owners said: 'The goal of this book is to tell Finn's story of courage and adventure to a younger audience with this children's book.
"Finn's family wants to commemorate Finn with this children's book to raise awareness for pet cancer and create it as a resource for children and families confronting pet loss or pet cancer in their lives.
"With your support for this book project, Finn's bucket list adventures can live on for generations to come and can continue to inspire families everywhere."
The fundraiser currently has a goal of $15,000 to create and publish the children's book.
Any money leftover from the fundraiser will be distributed between the National Canine Cancer Foundation, the Live Like Roo Foundation, and the Emma's Foundation for Canine Cancer.
Speaking about the decision to create the bucket list last month, Cynthia told the BBC: 'We know he's dying, but we are trying to make him happy.
'We will look back on this and think we made his final days the best we could. We're making the most of what we've got.'
Cynthia adopted Finn in 2012 when he was six weeks old, and since then the precious pooch has supported her through the toughest of times.
She added: 'He helped me through the grief when my dad died and now he's dying of cancer, too.
"It's a hard blow but really powerful to look back at how he got me through those times and now I'm going to help him."
