I can so relate to what you are going through. 3 years ago to almost the day, we were going through this with a 5 year old Bernese Mountain Dog. We were told he only had a week or so to live. After having a bad day, we had made an appointment for that evening. Once we got to the vet he perked up, grabbed his leash and started tugging me back to the door. There was no way i could go through with it that evening and went back home with him. The next day he was even worse so we made the appointmnet again. He didn't make it to his appointment time and passed away at home. To this day i'm not sure if i did the right thing by bringing him back home, but at the time i felt that is what he wanted me to do.
I know how hard this must be for you and your family right now and wish there was something I could do or say to make it better. You and Barkley are in our thoughts.
Of course you did the right thing -
Barley will know that you always did the right thing for him also, he is very lucky to have such a loving family and of course in return you are lucky to have him in your life. Whatever your decision, just know that Barkley loves you and knows you will do what is right for him. Enjoy your day with him.
Thinking of you often today.
