Have you looked into Bayshore Companion Dog Club? They should be pretty close to you. Bayshore Companion Dog Club
I teach at Princeton Dog Training Club, which isn't actually in Princeton it's in Griggstown. But I know many of the people at Bayshore, they have both competition and pet obedience classes, and agility. Plus they are in the process of building their own full time training facility, which is definitely a rare commodity in NJ!
Morris K9 Campus is definitely WAY too far a drive (and not a good drive either!), and from what I've been told they no longer have obedience classes except for very basic pet classes.
