Lola is 9 weeks today and we've had her for 2 weeks. Over the last couple of days, she has been lunging for my hands/feet/ankles/face and biting extremely hard. She is also growling and barking at me and OH. When she behaves like this, we squeal and if she does it again, we pick her up (she growls, bites and tries to run away when we try to do this), say nothing, and put her in her crate. I have read the bite inhibition thread and realise that pups will bite and growl etc, but I'm just worried that we're doing something wrong and pup is either scared or just doesn't like us! Writing it down makes it seem silly but it is really painful and disheartening that whenever I try to play with/pet her she's reacting in this way. Is this really normal? And could I improve my discipline methods? She doesn't get 'NO' or 'AhAh' yet and it seems just to make her bite harder.
