We are having the puppy biting issues also - It is more teething but hurts when he makes contact! I am trying the same distraction techniques but just hope in time it wears off. I was also having problems with him scratching at the screen door if I put him outside for awhile - so now have a Water spray bottle on jet stream so when he does it I spray instantly in his face. He seems to be settling with it.
Like you I hope this biting settles soon.
I have no idea how to add images on these forums LOL
