I really appreciate all the discussion on this here.

We're noticing a couple of symptoms in Binne, the scratching (though not air, around her harness), and she does this weird thing where she sort of looks like she's chasing her tail but she's actually chewing a foot and making strange sounds - not painful sounds, more like playful sounds, but we are watching her carefully. I cannot say I am not worried. This is our first time with the breed and she is only about 16 weeks.
