I'm so sorry for your loss. I've been there, too. It felt like my heart was ripped out. I was lucky and in the position to adopt shelter dog. She is totally different than my last one, but made her place in heart and I will definitely grieve for her when she is gone. I then adopted a 10 year old shelter dog who has also, got my love, too. He's thirteen now. I will grieve when he's gone, too.

Give yourself time. With some time you'll be able to look back on the good days with loved one and smile instead of cry.

Best Wishes to you.
