Sharon, I just had to pipe in. I chose amputation. I drove out to OSU from NJ, 9 hrs, stayed with a wonderful wonderful greyhound person, who charged me no money (I brought food), stayed with me at OSU during the surgery and pretty much handled all the difficult stuff while I was worrying over my Diamond. JoeJoesMom is who helped me. She has a lot of connections at OSU.
But, the most important piece of this is............my Diamond was 12 yrs old! I specifically went out there because they do see so many greys and I wanted their opinion on if she could handle being a tripod. Her age weighed heavily on my mind, but she acted 7. They agreed that age is just a number. She was strong enough for a front leg amp.
She lived 6 months pain free until unfortunately OS hit another leg. She never got lung mets. And she was happy. Very happy. I would do it again.
So please, look at Baxter's overall health, not his age. Good luck. And remember, whatever choice you make is out of love for Baxter. It's never the wrong choice.
