Stainless Steel Ultra-Plus Prong Dog Training Collar - Black - 2.25 mm x 12" Neck Size; 16" Chain Length

this is a great product that is working so well with leash training my german shepherd. for reference my dog is BAD leash puller who will literally run in place while walking and just doesn’t listen at all.. after putting on this training tool it has made such a huge difference & she immediately stopped pulling. i got the 2.25mm since so many trainers recommended this size and i purchased extra links (in case i needed it bigger or anything) & after adjusting the size it fits well on her. also i have even tried this product on my own neck and pulled harder than anyone would on any dog and it didn’t hurt at all. this is such a safe training tool that i would definitely recommend to anyone who is trying to leash train their dog. ALSO ofc do your research on the product so you know how to properly use this product and how to properly fit it to your dogs neck before purchasing !!

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.

Genuine and high quality Herm Sprenger collar from a trustworthy seller. I would not use anything else but a genuine Herm Sprenger...the quality of this brand speaks for itself and is well worth the price. Don't be fooled into buying cheaper alternatives as they are dangerous and less effective. The rounded prong-ends provide comfort while retaining their effectiveness as a training tool/aid. The links are easy to separate and re-attach making achieving a custom fit a breeze. Would buy again if we ever needed another.

Have two dogs who were serious "pullers" and tried all the other solutions to solve that problem, but nothing worked like the prong collar to stop the pulling. I tried a generic brand but the links were huge and they could not be finely adjusted to the point of working well without being too loose or tight. The Herm Sprenger collar came highly recommended. Although twice as expensive, the links are smaller and allow for perfect fit for effectiveness without discomfort when loosely worn. Solved our leash pulling problem for both dogs.

As a professional dog trainer, this is the only prong collar brand I will use. It works great! Once you get the muscle memory down, it is very easy to put on and take off. This is my favorite size. The micro is typically too small and too harsh, and the medium is typically too big and hard to take off. My dogs love their prong collars!

Keep in mind that 3 inches of the size is for the connection to the leash. Do not count that in the size of the neck. Great quality and function.

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.

It works but you'll have to use it forever. Like it won't really teach your dog to loose leash, it'll just teach your dog to loose leash walk ONLY with the prong collar on. If you want to teach your dog to actually walk without it, you'll have to train your dog without it, using U turns, treats, stopping, etc. But it's a quick little hack for when you need to go to crowded areas or mall or whatever. Anyways you want to make sure you have the prong really high up on the neck and behind the ears, otherwise your dog will barely feel it.

Still lasting without any problems with the prongs there’s a possibility some people don’t know how to use this device needs to be just underneath the dogs ears nice a snuggly so it pinching the dog if pulled but I found out sooner or later 4mm isn’t necessary 3.2 is better if your dog has a 25 inch neck if your dog has a bigger neck then get the 4mm This is the 2nd one I bought off of Amazon the 1st one was exactly what I ordered this one doesn’t match up Still seems to be stainless steel and has the swivel on it at least

Great quality, helps with leash pulling

A entrega foi um pouco demorada, mas ja era de se esperar, ainda assim chegou antes do prazo. Como no BR poucas pessoas importam da HS, gostei de ter no catálogo da amazon. Sobre a prong collar em si, é de muita qualidade. Fiquei com medo de ter comprado o tamanho errado, mas a de 2,25mm coube certinho no pescoço de 38cm do meu cachorro. Ainda vou começar os treinos, mas já está aprovada!

Produto excelente! Chegou antes do prazo estipulado!

Excelente calidad, esta muy padre complio totalmente con mis expectativas
