I'm so, so sorry for your loss. I pretty much cried off and on most of the week when we lost our dog. I'd think, oh, I better let the dog in or feed him and then realize he was gone. Or I'd think, gee last saturday DS and I took the dog for a walk, gave him a bath or he was laying underneath the trampoline looking up at us. It was better when I wasn't home with all those reminders.
Have a good cry. Allow yourself time to grieve. Your dog had a wonderful life and knew you loved her very much.
