There's nothing pleasant about what you're experiencing. I lost my boy this past August to heart troubles and his condition near the end very much resembled what you have described with your boy. It wasn't easy. There isn't a day that goes by that I don't ache for him. But I will tell you that after I helped him make his journey to the bridge, I felt as though this huge weight lifted off of my shoulders because I didn't have to see him suffer anymore. I miss him terribly and I always will, but I certainly don't miss seeing him the way he was during his rapid decline. If I could go back, I would have ended his suffering weeks prior to when we made that fateful decision to let him go. Helping them to the bridge is the last loving act of kindness we can do for our babies who, in turn, bring so much joy to our lives. After we helped our sweet boy to the bridge, my husband and I received the nicest card from our vet who had suggested that if Buddy could talk, he would thank us for having the strength to end his suffering. I have all the confidence in the world that my vet is right. Hugs to you at this difficult time. A lot of us have been where you are and we can certainly sympathize. You will be in my thoughts and prayers.
