here are all the dog movies I remember watching as a kid (mostly 90s/2000s, live action) plus some new ones

Tags: "happy" means it's an easy, not upsetting watch, "sad" means it is a heartbreaking film and the dog probably dies (might have an uplifting resolution but it is still heavy and will probably trigger feelings of grief if you've dealt with the loss of a pet or loved one), "???" means I don't know or remember, and "iirc" means "if I recall correctly"

other ones I remember but less fondly/as young:

I didn’t watch lassie as a kid but I read it a little and liked the movie a lot when I watched it for the first time in 2018
