Bulldog hates other small dogs

I have a 3 year old English bulldog who is generally very happy and playful with people and big dogs, but she always tries to pick a fight with smaller dogs. We also have a Labrador at home, so I’m assuming she thinks she’s a big dog (she’s actually smaller than a typical bulldog at around 19kg).

When we run into a small dog during walks or gatherings, if the small dog is close enough she will chase it and make LOUD noises that we don’t normally hear. I can usually control her fairly good on the leash, but it’s like her internal instincts kick in and any training goes out the window. I don’t think she ever bit another dog, but it freaks out everyone involved and makes it completely awkward to deal with.

How do I handle this? I feel like correcting her on the spot does nothing. Walking away immediately somewhat works, but doesn’t feel like an actual solution.
