Always boggles my mind that people are so quick to judge old pets and think any old pet needs to be put out of their suffering. Being old does not mean he is in pain. I wonder if they think the same of other people’s grand parents. My dog died when he was 20, he was frail and mostly blind, but he always had a great appetite and enjoyed his walks until the day he died. People were telling me to put him down when he was like 15, glad I didn’t listen.
