When John Unger had suicidal thoughts after a breakup, it was his dog Shoep who brought him back from the brink. This photograph shows Unger cradling his friend in lake Superior to soothe the dog's arthritis.
I think that picture was originally posted on Facebook and when more and more people saw it the donations started to roll in.
Instead of keeping it all for himself the guy took all the extra money and set up a foundation to help other dog owners pay for expensive medical treatments they may not otherwise be able to afford.
There are some cool pictures out there of his dog getting laser treatments to help with his pain.
