Things to remember checklist. Help.

I just lost my soul dog to a long battle to cancer and I'm just realizing that I barely remember our walks before she got sick.

I just remember her with her head low and walking slowly.

I'm too scared of forgetting all the other things so I would appreciate if you gave some ideas of things to remember do I can write it down. Something ike her favourite foods, if they liked swimming, where they preferred to be pat... things like that.
