i want my dog part of the wedding and fiancé doesn’t

This is more of a vent. I’m completely obsessed with all 3 of my pets (cat and 2 dogs) and while I probably can’t involve my cat and younger dog since he’s a little rambunctious I have my small dog Brooklyn who is an angel 👼. My fiancé loves our “kids” but not to the extent I do which I’m completely fine with. I want to include Brooklyn in my ceremony as a possible flower girl - my priest is going to look into if they’ll allow a dog in a Catholic Church since they seem to be more relaxed than I imagined. My FH absolutely was not into the idea of Brooklyn being the flower girl whatsoever. Ok. So I suggested if we maybe include her in our engagement photos next week and he is against that too. I guess I’m just frustrated because I want to respect his wishes but I want him to respect and at least consider mine. I do plan on having a wedding cake topper with the two of us and all the pets and a little station with them by the guestbook area.

What would you guys do if you were in my shoes? Just accept it? I know it’s probably a little hard to understand my frustration if you don’t see your pets as your “babies” the way I do 😕
