Oh my, all these responses are so meaningful, considerate and straight from the heart. Such good points brought up and to consider. Twice, I have been at the crossroads of this type of situation, and both times, wished I had not gone for the extended treatments and just brought Dixie (my first dog I got at 12 years old, a brittany spaniel bird dog) and my Ol' Sally hound dog (that I had for 16 years) them home and allowed them to die with me at home and not at the vet's office. I did not expect them to die there, it was in the hopes that they could be helped, you know, just stay overnight for observation. Please, Dear Lord, help me next time to stand by that decision and bring them home, especially if they are older. Did I have their best interest at heart? Sure, I did. Was it also partly cause I wasn't ready to let them go yet. Sure, it was. Life's a funny thing and we all just try to work it through the best we can at that point in time.
