One of my little Silkies is being very strange. When I pick her up she spins her head completely around to face the sky then tucks it under her body. Then when I sit her down she keeps her head tucked and waddles backwards. Think there's something wrong or is she just goofy? I didn't see and mites or anything, my only idea would be her ears bothering her. I watched her walk backwards in circles shaking her head underneath her for at least 3 minutes the other day.
