Herm SprengerNeck Tech Stainless Steel Prong Dog Training Collar with Quick Release Buckle Pet Pinch Collar No-Pull Collar for Dogs Made in Germany 19 inches

The one I received was too short...so I bought a new one AND spent a little more on the Martingale and "swivel D".I made two "how-to" videos for this product.

I love how it looks on my pup. However, I may not be using it until he is better trained with the prong collar I was using. He didn't react as well to this one. But he is only 1 year old and I anticipate a change over to this one as he grows up and is more obedient.

Very nice looking too big though for my puppy, got it for when she gets older.
