My yorkie is three months old now and when we first got her three weeks ago all she would use was her puppy pads, but now that she can touch the carpet she has been using the floor more than her pads. is there anything that i can do about this? also, she has bee excessively biting the face and hands and i dont want to discipline her too much. is this just a puppy phase or can this become a problem? This is my first yorkie and any additional tips would be very very helpful

thank you
