I have had to put down a couple dogs (and a cat) in the past, and it really is a terrible thing to have to do. I have a 7 year old dog right now that has been going through Chemo, but she is doing well. I know her time will come though within probably the next year, and I am not looking forward to it. I would consult a Vet with your wife and ask for advice. They will usually give you an honest opinion of what is best for your situation. If you did not live in a cold weather state I would suggest an outside enclosure when you are not home.
