Books with this dynamic? … Silly golden retriever character as love interest/MC?

First 4 are from «Tamen de Gushi» by Tan Jiu and the others are from «Sadistic Beauty: Side Story A» by Woo Yeonhui, Lee Geumsan.

Weirdly specific I’m sure, but I’m obsessed with this dynamic! Any level of fluff/spice is okay as long as the characters aren’t teenagers.

Books I’ve read that reminds me of this dynamic: «A Dark and Hollow Star» by Ashley Shuttleworth «She Gets the Girl» by Lippincott/Derrick «One Last Stop» by Casey McQuiston

Thank you!!!
