My first dog, a black lab named Shadow, passed a month and a half ago. I know how it feels, and I am so sorry for your loss. Although I still miss him very much, I got my GSD named Chief last week. So Id say it was about a month and a week until I got a new one. I got another one because 1: I love animals and 2: I needed to move on from my old dog. Its ok to still think about your old dog, but getting a new one will help you get over him and focus on something new. Anyway, I loved my old dog and my new GSD. I enjoy my GSD and he plays very much! I hope you will love your new pne just as much as your last.
