I remember going through what you have and having to make the tough choice in the end to do what was right for our dear friend.
A good long term relationship with your vet is priceless. We are very lucky to have ones (plural since they are a couple) whom we trust and who demonstrate a true compassion for the animals in thier care.
Hopefully yours discussed with you some measures that you can take to potentially help with your pet's condition. For us, a daily dose of glucosamine really seemed to slow down the progress of the arthritis and gave us a few more more happy years.
I wish you and your families all the best.
