Dont give up wolf_q, sheeshh its that women and her dogs that are the problem, nebo is doing what dogs do, if that was your first lesson then he bound to want to see all the dogs.
I would keep going and just ignore her completly, and if nebo gos over to her again grab him a say to him "dont go near that women nebo she's evil" or somthing just let her know that she's not going to push you out of the class, like she's probly trying to do to all new comers.
good luck Ky and Rio
