On the dog movie myself, husband, and especially my middle are the same way. My oldest wanted to see “A Dog’s Purpose” and my husband said he would take her (I don’t think he realized what it was about). He was not happy with me after. I actually felt bad...my oldest wants to be a veterinarian and will probably succeed at it and be a good one since she doesn’t see a problem with those movies. My middle at the end of last year watched in school some movie where the dog is left at a train station for basically his whole life. Basically she came home sobbing and for the next week would periodically start up again. We have a pact now. If someone wants to show her an animal movie she does not want to watch she can call me and I will come get her or arrange to have her not watch it. She is the kid who is okay with other scary movies (Star Wars, Harry Potter, Jurassic Park) but a dog or other animal in peril is her undoing.
