You both need to talk together about the topic of another grey, or two, so you can work through this and make the right decisions. You will know when you are ready to add a new member to the family. Everyone has a different way of grieving and finding resolution. I never thought I would be able to adopt immediately but we did. For my husband, who lost his heart dog last year, an immediate adoption gave him a new companion to care for and comfort him. For me it turned out to be the same answer. Willow helped me find peace in the loss of Darwin, my heart dog, and made life much easier to cope with. (It's almost scary in the similarities between her personality and Darwin's) We also had the satisfaction of knowing that even though one door closed, another opened for us to help make a difference. We will never forget the ones that passed and always remember to enjoy the ones we have now. Best wishes to you both. May another greyhound, or two, find their way into your lives to give you comfort.
