Bella is adorable. I would recommend taking Bella to the veterinarian to make sure there is nothing medical going on with her. If that comes back as just behavioral I would recommend getting a trainer to work with you and her. They will be able to see what is the trigger and work with her and you to stop the behavior. If the trainer evaluates her and determines medication is needed then your veterinarian can provide medication to help. Thank you for using Petco Pet Education Center, formerly Petcoach.
