No. I rather have 10+ beautiful years in the companionship of my dog than nothig at all. I'm usually a "glass half empty" kinda person but when it comes to my animals I feel better to have loved and lost than to never love at all.
My grandma feels the same way as you though, she won't have another dog after the last one went to the RB at 15 years, 4 years or so ago.
