Both myself and Mrs Geared are very sorry for your loss, adventure boy was the most handsome pup we'd ever seen and he seemed such a gentle soul even in pictures. Your post was a touching tribute to the best of boys, it's simultaneously heartwarming and heartbreaking to read about his decline, but how he kept his lovely temperament despite his failing senses.
He had a long and loved life, and I wager he's travelled more than most people too! Whilst I'm sure it weights heavy on your hearts, you made the right decision, even if it was the difficult one.
Gone but never forgotten Thorfinn Skullspliter 'Adventure Boy'
