How do you deal with an 'on the way out' pet?

I dealt with this a couple years ago. Jr. was 18 or 19 had a great life. In the end he got a mass in his stomach. Vet says we can operate 2 to 4 thousand bucks.. I said are you gonna make him younger? We ended putting him down. Sucks He is buried out back where roamed. First picture he is about years. Second 18+
