This is a very bad habit indeed! This is something that needs to be stopped immediately, as it could get Nalah and you into big trouble. First off, I would get her a muzzle to wear when walking her. Do not take it off, and this should prevent her from biting people. Do not allow her in your yard unobserved so there is no risk of her getting out and biting someone. Next, I would consider spaying her. Intact dogs can be aggressive due to wanting to protecting their territory, and spaying her may help reduce some aggression. Finally, I would make an appointment with professional behavioral expert. I never recommend owners work with aggressive dogs on their own because of the danger and risks involved. Aggressive behavior is something best left to the experts. I would speak to your vet about a referral to a professional behavioral expert. Good luck, I hope this helps!
