Hi, we got our first lab at 8 weeks old. She is now 7 months old and recently has destroyed my sons mattress and bed. She has never been crated and has always slept in my sons room. She was spayed a couple of weeks ago and the past few nights she has woke up at 3am and after taking her outside to toilet, she has not settled back down. She jumps up on us and not sure if she is playing or not but seems to be trying to bite us. We have tried distracting her but this only lasts a few minutes and then she will jump up again and nip at us. If we say ‘no’ to something she should not be doing, she growls and shows her teeth and snaps at us. Is this aggression and what should we do as we are exhausted with the early rises and do not know how to deal with the snapping.
