How about getting her a pendent necklace that features a dog and a physics equation or image? There are many artistic pieces online that beautifully combine the two interests. Alternatively, you could get her a book on the science behind dog behavior, or a biography of a famous physicist. If your girlfriend enjoys puzzles, you could consider a dog-themed physics puzzle, like a puzzle featuring famous scientists and their furry companions. Another great option would be to plan a visit to a science-themed museum or exhibit and bring her beloved dog to make the outing extra special.
Or you can get her a star map with the date of your anniversary.
