Welcome to the board. First, let me say how sorry I am for your loss. Many of us here have gone through it and, trite as it may sound, there is no pain or loss that is quite the same as losing your dog. For me, when my first GSD passed away, I had no interest in getting another. A few months passed and I decided, while I did not want another dog, I enjoyed the time with dogs and began volunteering with a local GSD rescue. A month of seeing and meeting all those dogs and I knew I was ready for another one to come into my life full time. So, I guess the short answer is when you're ready, you'll know.
