15 years later, poor Birdy was a much older dog, suffering from cancer. His health had got rapidly worse before the now adult Gordon's eyes, who was trying to prepare to say goodbye to his faithful friend...
With this in mind, the man dedicated a very moving hommage to his dog on the internet. Gordon published three photos where they assume the exact same poses, showing the physical transformation over the years since the first shot was taken.
This touching gesture was a way for Gordon to mentally prepare for the moment that he so feared:
[He's] back to his "normal self" now but after several tests it still might be cancer. So it could be 6 months, it could be 2 weeks... We've had a ton of good times, unfortunately for all of us at some point it'll be time to go.
Enjoy these three wonderful shots, the first taken 15 years ago, and the others more recently. It's time to get out the tissues.
