I didn't know nearly enough about SM before joining this forum, and I've spent the better part of the day watching the videos and reading the symptoms, and now I'm worried. Winston stops to scratch at his collar while on the lead, at some point every time I take him out. He scratches at his collar in the house as well. I had chalked it up to it being his first collar and just getting used to it, but now I'm not so sure. He rubs his face on the floor at least once a day, which I had assumed was just part of his puppy exuberance. He doesn't yelp or act like he's bothered by any of it. At what point should I worry? He's only 12 weeks old. Upon questioning, DH told me he came from a BYB, which I'm not pleased with at all. He said both parents appeared healthy and happy, well groomed and trained. What is my next move?
