I had seen Flynn at dog park a number of times before his owners asked for me to give him a relaxation massage. Then I received an email several weeks later informing me that he had died suddenly.
His owners felt it was important to let everyone at dog park know of his passing.
Rest in peace, Flynn!

Awww, this is sad! 😦
How sad, but good of them to think of those at the dogpark too, in their time of grief

Sorry to hear about Flynn, how kind of his family to notify everyone.
