General "Woof" Collar Tip: When you need adjustable collar with more than just 1,2 or 3 notches/holes purchase one of our collars w3ith confidence
We make our standard collars with at least 5 notches/holes to give your dog enough adjustment flexibility when your dogs goes on diet or grows/ gains some weight
No need to purchase new collar

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.
