Hi, We have a 3 month old puppy and every time we put her on the armchair she completely switches and starts continuously biting us. We can't get her to stop and before she used to be fine?!

I would recommend keeping Nina off the furniture. She is seeing it as her territory and is defending it. Keep her to the floor and people on furniture at least until she realizes she's not the boss. I would strongly recommend basic obedience training classes as well to get a good behavior foundation. The website and books by dr Sophia Yin may also be helpful. https://drsophiayin.com/product/perfect-puppy-in-7-days-how-to-start-your-puppy-off-right/ Best of luck and thank you for using PetCoach.
