I’m sorry, Ski. At least you had the additional time you needed to accept the inevitable and prepare a bit, and give him lots of love and attention. Try not to have any regrets, he knew he was loved and you made sure that his passing was easy and not prolonged. It was the best you could do under the circumstances.
*hugs* Anyway, I hope you were able to get a lot of pictures of him to remember your time together. That is my one major regret with my dog Holly, we never really took all that many pictures of her, and I really wish we had.
