Herm SprengerStainless Steel Prong Dog Collar with ClicLock Buckle - for Small Medium Large Dogs – Ultra-Plus Training Pinch Collar with Quick Release - Made in Germany (23in (58cm) x 3.2mm)

Great fit, doesn't slide down the neck like the other HS models. My dog is very responsive and I really don't have to correct anymore.

Do not waste your money on any other brand. I was told this for a long time and just laughed because they all look kinda the same, but when I broke down and bought this brand, WOW. The difference is day and night! Just buy the right one to begin with. Save yourself headaches and money.

Pro:Clip is much easier than connecting a link.Since it doesn’t tighten, it doesn’t distribute the force. This give more directional cues to the dog. It’s like having power steering.Has prongs on back so you can even nudge dog toward you when facing dog.Con:Not a slip design so doesn’t distribute the force. Maybe harder on the dog if they run and get stopped suddenly.

Pickles changed into a very leash obedience once I put the collar on. You can adjust by adding or removing links.Hard for me to do as my fingers are weak

Very well built

The buckle does not allow the collar to tighten. When there is pulling, all the pressure ends up at the throat. Defeats the purpose. Buckle cheaply made. Very disappointed!

with more prongs touching the skin, there's less pressure per prong and less "compelling information" received by the dog. The back of a dog's Neck is very tough with strong muscle and thick skin. Having prongs there doesn't make sense, IMO.PROS: if a dog's leash got caught and the dog hung itself or panicked to get away, it might be more likely to avoid injury/strangulation in this collar because it doesn't tighten around the neck. I'm entirely sure about htis but it seems like it would be less dangerous
