I am so sorry to hear of your loss of such a wonderful companion. That was a wonderful picture as well. I have been on this forum for a long time but evidently I do not have enough postings to post attachments, or I would have posted pictures of my precious Lily, that we lost just a week ago.
There will be private times now that you will find that were not necessarily private time before your loss. There will be times that you will miss your special friend, when nothing will fill that void.
I too am going through a tough time with memories. I now have another puppy that occupies my time but, there are always those special times that keep coming back. I have my time with them, then go about everyday life.
Good Luck on this journey.
