My Striker lived to be 11 years 9 months. My female is now 10 and aging quickly. I met a 13 year old female years ago, that moved around quite well although she did look her age with a beautiful white face her body had withered to a frail little dog. She was the oldest boxer I had the pleasure of actually meeting. I'm curious how many here on BW have very old senior dogs and would you share their age and health issues and/or concerns.
