Our great little dog is starting to show his age, 11 years old. It makes me sad, but I've thinking about what we'll do when he passes. We've always enjoyed having a pet in the house these last 20+ years. I don't think I'll be ready to make another 10-12 year commitment when the time comes. It's harder for my wife to imagine our household without a pet than it is for me. We're both in our mid 50's. Your thoughts/experiences?
