Schoep, the arthritic dog who became an Internet sensation last summer when he was photographed floating peacefully in Lake Superior in his owner's arms, has passed away.
The 20-year-old dog's owner, John Unger, announced the death of his best friend on Facebook on Thursday evening.
He wrote, "I Breathe But I Can't Catch My Breath... Schoep passed yesterday. More information in the days ahead."
Their photo and story began circulating nearly a year ago.
Last July, Unger thought he was mere days from needing to put then-19-year-old Schoep down, and asked a friend to take one last photo of them together.
That photo was seen by millions and resulted in an outpouring of online donations and support. The help Unger received allowed him to afford treatments to ease his dog's condition.
