I am so very sorry for your loss, but please don`t beat yourself up. You made the ONLY decision possible as a loving , caring and responsible pet owner. It sounds like your little friend was in quite a lot of discomfort, and although its the most natural thing in the world to want to keep them with us for longer, sometimes we have to give them the last gift of love by taking away their pain. Of course, by doing that, we then take on the pain in the form of unbearable grief, and question ourselves over and over, even to the point of blaming ourselves for their loss.
I also blamed myself 7 months ago when we had to have our special little dog put to sleep, and from being on this forum for a long time, it seems a lot of us do question ourselves. The very fact that your dog was 14 years and 10 months old shows just how very much you loved and cared for him, and although you won`t believe it, you will slowly start to feel a little better and realise that when he needed you, you where there for him . He really would want to thank you for that.
Take care, Jackie
Thanks so much Jackie. It is a daily struggle, but I can see what you say is true
