Tell me if Im overreacting plz

So I booked a Christmas shoot for our family back in August and its coming up this Saturday. Its in a nice studio with a great photographer friend who shot our wedding. I already put a deposit on.

I reminded my husband about it and he asked if its dog friendly so I asked the girl and she said since its not her studio they dont allow dogs. My husband now is refusing to go because he said the dog is apart of the family and should be in it.

I love our dog and he’s definitely apart of our family but this is for our daughter and memories she can look back on. Its also a maternity shoot cause im 31wks pregnant so now hes ruining that too…

Am i overreacting by being so upset that hes canceling the whole thing because of the dog…. i would hate to cancel so last minute cause shes a friend of mine.

I told him I am going without him with our daughter and it will be a mommy and me photoshoot then…

Now hes turning it on me like he cant believe i didnt think of the dog, that clearly hes not important to me… and that if i wanna sulk then I can just sulk…
