Herm Sprenger Stainless Steel Prong Dog Training Collar with Swivel Ultra-Plus Pet Pinch Collar No-Pull Collar for Dogs Made in Germany 3.2mm x 23in Medium

Well-made, heavy chain that is one of the best we've ever worked with for our dogs. Works great with our large rescue dog that we are currently training. Our dog doesn't pull on this chain like he did on other collars or chains, allowing us to train him more effectively, which is great. This chain is more comfortable on him, and it's only when he's really pulling against the leash that this heavy chain reminds him to calm down. He's a much happier dog than when we first rescued him, and professional trainers told us he was one of the strongest-willed dogs they'd ever seen. Now he's well behaved, so we take him to many more places we all enjoy.

Yes, I was absolutely hesitant to use these collars initially. I avoided it and probably "over treated" my two pups trying to train them, but maybe I was actually bribing them. I had two dog trainers recommend this collar and I understand others may not. My two pups are 7 different breeds (did the dog dna testing) and they are large dogs. They are super, incredibly sweet, loving dogs. I was afraid I would cause them to distrust me and I was afraid I would eliminate some of their loving, sweet natures by using this training collar. I was, very thankfully, so wrong. Because they are large puppies (67lbs and 80lbs), they do not know their own strength, get over-excited, and are more focused on getting what they want than on their training walks. Used correctly, and I sincerely mean correctly, they are fabulous training tools. I must also admit they are terrific safety features for me since my dogs will not take off after a squirrel or anything else while I walk them with these collars. I quickly believed all the information in the many, many YouTube videos I watched and told by the trainers I noted. These collars are a very humane way to train dogs. Again, this is only true when used properly. Admittedly, I originally figured these collars were worth a try and I did not have to continue using them if I did not want to or if I did not like them. Before I used these collars, I used harnesses that were designed to reduce pulling when walking. I would practically "fight" them trying to restrict their moving forward, sideways, or any direction they wanted to take me. My pups did not understand why they were being limited and it was a continuous battle. Truthfully, walks were not fun nor too bonding for us. Once I used these collars, they learned almost immediately that they have control over their correction. It helped them choose to walk well and focus on our walking. Yes, I heard two light yelps the very first time. Yeah, I hated it. I knew they were not hurt or choked at all. They were surprised. Do you blame them? They did not know what these collars were and they were used to tugging me along on walks. That was the only slight yelp I've heard since using them. My neck, shoulders, and back also thank these collars. Most importantly, my dogs actually like them. Sincerely. They know every time we go on a walk they wear them. I pull out the collars and they are genuinely excited. They are very well behaved on our urban streets and I get compliments for my just turned 1 year old dogs. I will emphasize one more time that the collar must be used as the training tool for which it is designed. Following the dog trainers' instructions will make these collars pleasant. It helps my dogs to know their limits, correct themselves (they have the control), and get to enjoy our walks. And, yes, I give treats with these collars on while walking when they do what I ask like sit at a corner. I really do not use the collars for more than leash walking. I noticed that using them for walks was enough for my dogs to train better with me in other settings.These collars are well made. They are strong. They are very sturdy. I appreciate that they come in black. These collars are stronger and more secure than the ones I see in pet stores. Like any training collar, they will fail some day. Because of that, I use a carabiner to connect them to their regular collar when walking. I also purchased additional hooks so that I can avoid that potential day by changing hooks out.

Works well for a 5-year old standard dachshund who pulled like a mad dog, changed the way we walk in a small 10-minute session (I recommend you watch American Standard Dog Training videos on Youtube first, Garret explains the corrective U-turn and sudden stops technique really well and simply). All in all a great tool for making walks pleasant again! Really good quality, too!

I’ve been following a lot of professional dog trainers who rave on about this brand of prong collar, I see why now.Not only is there huge customization options that no other prong brand offers (chrome, black, & gold metal options, various widths for any size of dog, etc). I also purchased quick release buckles that I switched out the middle plate this model offers because I prefer that feature to a collar I’m regularly taking off & on. For my pit mix who has a 16” neck I kept 2 prongs on each side and it fits her well even with all her extra skin, also shown is the amount of slack it gives her, a healthy 2-finger gap. I also purchased one for my husky mix and he has about 1” less in diameter in his neck, and has 1 less Link. They both walk beautiful in this. There’s next to no slipping on the neck, it stays where you put it which the last collar of another brand I had certainly did not, despite it obviously being fitted the same. The links are easy to remove, coming from a small female with 0 grip strength. A grandma could pinch the links and take them apart, it’s very straightforward. Quality is great and well worth the price, I see these collars standing the test of time. They’re not too heavy, and not light and flimsy either. If there’s any problems I run into I’ll be sure to update this review, if I don’t update, they’re still perfect!

This collar helps so much with control and training my very enthusiastic and very STRONG 90 pound german shepherd. It makes walks and life happier for us both! Very high quality collar - worth the price.

Bought a hidden prong before this one, and while it was better than a regular collar for my dog's pulling, it didn't really do much for leash training.This herm sprenger is working much better so far. My dog is particularly stubborn but she's starting to get better in just two days of this one. Not perfect, but noticeable better, and most of the time loose leash walking already. She is being more conscious about not pulling my arm off like she was still doing with the other brand. This is good because she is no longer choking herself out pulling, so while a few corrections are needed here and there, it is better for both of us than the other collar.I can't speak for knock off brands and their quality, they probably all do the same job, but I went with the original and most recommended brand to avoid issues, they quality is good, and it actually works. I look forward to a future of longer dog walks, and her no longer coughing from pulling so hard she's choking herself.Four stars because I'm not a fan of the buckle design or the fact that it's in the center. I know there's another with the buckly in the back and I wish I wen that direction, but a normal buckle clip design would have been easier to use than her sprenger's designed buckle.
