Grief never has a time table and I am so sorry for your loss. I'm also sorry I did not see this question until today! I think that grief hits us all a bit differently. Some of it takes us surprise as well. I can look at a picture of Griff (who died in 2015) and still start to cry for missing him. I think it is a normal response to never want to go through that pain again and some people actually will themselves to feel that way. They do not want to experience the pain of losing another pet or something they love so much. That is a normal response. It becomes a personal decision. I know myself that I've been grateful for the distraction - for having another dog to pour my energy into to not replace Griffin but to somehow divert my grief into something positive. I know he would want me to be happy and not miss him terribly so that is how I self-talk myself into it I guess. It is rewarding to have another dog and see how they respond to your love and attention. It cannot replace the one you lost but it is rewarding and heartwarming nonetheless. Good luck in your journey and I am very sorry for your loss.
