I know it's too early to consider getting another dog- you need to grieve over this one, but after some time has passed, I hope you will get another one. There are so many animals in need of good loving homes like yours. There will never be another dog like the one you lost, but, you'll find that a new dog eases the pain of the loss greatly- I know this from personal experience.
so sorry for your loss.
I hope he goes to Walhalla Wolfhound Heaven and can run around and enjoy himself for etertity.
