General "Woof" Collar Tip: While many collars manufacturers cut on details to bring costs down on the account of your dogs comfort we believe that dog comes first.

I prefer the steel "prong/pinch" type dog training collars to choke chains as I have found their use to result in easier and faster training for both the dog and the trainer.
I suggest that teaching "heel" is a good place to start with the prong/pinch collar.
