Awwww, that face is a heartbreaker... she looks like she's telling you she's glad to go and it's OK in the car pictures...

It's not too soon to look for another dog if that's what is right for you. Everyone's grief process is different. Saving a 'big black dog' is saving a life, too. BBD's are usually euthanized at a much higher rate than other dogs-- people are afraid of them and they just aren't very adoptable.
