My Chihuahua snorts too. I definitely suggest taking an obedience class with your chihuahua. I've never taken a class with my chihuahua because he was a rescue who was abused for 6 years before I got him. He's afraid of everything. I have taken an obediance class with my pug though and it was wonderful.


edit: I took a class at PetSmart, it was $100 for an 8 week class.
