This is her day and very important for people into those things, so I would definitely get her thoughts on it. Also, dog aggression has a huge genetic component to it in the bully breed.

Yes you're right, I know she won't mind if I bring my puppy, they won't be in the way at all, and it'll keep me away from the baby shower as well lol
