There are small things you can do to assert your dominance.
Don't feed her at the table.
Don't feed her until after you've eaten.
Establish boundaries like not letting her on the furniture.
Always proceed her into a room. If you're coming back from a walk, enter first.
When she does something you don't like, force her into a sit/stay position by pushing down on her butt gently. Over time, lengthen the wait period between the stay and the release.
Don't repeat commands. Say something once then make her do what it is you want her to do.
When Chance was younger and was into jumping up like a crazy thing, our breeder taught us how to gently flip him onto his back by standing on one of his sides, reaching under him and grabbing his opposite legs. He eventually became good at evading this
but putting him onto his back and actually forcing him not to get up until I gave him a release word taught him who was boss. I can now flip him onto his back and walk away from him and he will not move until I say so.
All in all, be consistent and remember that training is ongoing. Just because you learned something in puppy class doesn't mean it doesn't need to be reinforced. Chance learned to walk without pulling in obedience but a year later would drag me down the street if I let him so every time we go out on a walk, I do corrections, make him sit to cross the street, sit to wait for the elevator etc.
I wouldn't be surprised if your dog starts responding even better toward you if you establish yourself as an alpha in her eyes. Just remember: Bulldogs are not labs. They are loyal but they don't aim to please the way a lab does. And they are too smart for their own good!
One last thing: Make sure you and your husband are using the same commands. Training Chance was made 100x harder by his dad who forgot commands or didn't follow through with them.
Good luck! Don't give up on her and don't let her give up on you!
