To get your puppy housetrained you should keep her leashed while in the house, and with you or your bf at all times. Watch her cues, and take her out whenever she needs to go, praising her for success. It won't take long before she gets the idea again. What you can't do is take her out on a set schedule, ignoring her behavior in between outings...or you end up with the situation you're now facing😁 It'll be over soon!
It's not the size of the dog in the fight, it's the size of the fight in the dog. Mark Twain
