[TOMT][Anime] Show where girl confuses boy with her family dog, but because his hair is soft-looking?

Hello! I saw this short in an instagram reel. I believe the name was 3 words, (something) and (something).

I believe this took place in a school and the girl felt very bad that she called him by her dog's name. He then bent over because he was tall and let her pet his head.

It is not the kanojo pet one. It is also not dog and scissors. It's also not the dog from FMA:B. We (friends and I) searched anything with a dog, but the issue is that the guy isn't a dog! I just didn't see anything else in the Insta reel.

It looks comfy and I've been through a lot lately. Please help me, thank you!
