Oh I am so sorry to hear about your sweet Lion! He is now at the Rainbow Bridge with all of the other good doggies. It's too bad your dad decided to put him to sleep. If he was only 9 years old (same age as my Reggie) and in good health....dogs can live with being blind and deaf. Of course all of it depends on the real quality of life, I guess. My Smokey is 16 years old, can't hear much, and probably can't see much either, but he still gets around. Anyway, I'm sure you miss Lion very much, and I hope you will be comforted by your memories of him.
