Welcome and sorry to hear about your loss. You will know when it is time. I lost my first and only pet, Dorian, a tri, last year and thought I would not be able to get another sheltie for a long, long time. But, I found myself, surfing the web daily a week after he died. A month and a half later, I was picking up my new puppy at the airport, and then 4 months later, I flew out to get a second one. Dorian will always hold a very special spot in my heart and I will never forget him, but I needed the love that only a dog can provide. I was alone and the way I see it, Dorian sent me two shelties to keep me company until the day that we are all reunited forever. Take your time, and you will know when to get another furbaby.
