Halloween // Family of 3 (+ dog?)

This is our first Halloween with our daughter and I have no costume ideas! By Halloween time she’ll be 9.5 months old.

Our family consists of me (mom), my partner (dad), our daughter, and our dog (a chihuahua/beagle mix).

Does anyone have any ideas? I feel like my brain is mush because I can’t think of a single thing. My partner suggested Brian, Stewie, Peter and Lois but I don’t love that.

Our dog doesn’t really need to be included but he will be walking around the neighborhood with us so I just think it would be cute lol
