Herm SprengerBlack Stainless Steel Prong Dog Collar Training Pinch Collar No-Pull Collar (2.25mm Small)

This choke collar is awesome. It chokes like ever other collar (I've used another knock off brand borrowed from a our friend) the prongs are NOT sharp, it is black and after about 2 weeks worth of usage it shows no chips or flakes in the color. I bought the 3.25mm and its smaller than I expected it to be, obviously this is a measurement so consult a ruler to choose the correct one. It is much lighter in weight than the other one we were using, that being said it feels strong and secure just built out of better metal perhaps. Anyway our four legged son is a young energetic black lab about a year old and about 65-70 lbs. He pulls like a wild man and often will wait while you walk and then sprint trying to break free. This collar dose the trick the pulling is minimized greatly and he never tired to break free. We have tried heeling for a short break ever time he pulls but we don't have 45 min to use the restroom. When we tried the gentle lead he would walk about five feet and nose dive trying to scrape it off, after a few times on concrete and gravel we decided he was doing more harm than we were good. This collar is amazing it makes walks enjoyable again.

I have a sometimes reactive male Doberman that weighs 80 lbs, and even though the links are small/thin, the collar is strong enough to hold him. I did have to order a couple of extra links from the Herm Sprenger website because of his thick neck.

My Belgian Shepherd/Tervuren has been East to train with the exception of loose-leash walking. He liked to pull and, at rare times, lunge. After waiting too long to try a prong collar, I was impressed by how quickly (immediately) he responded to it. Although on a couple of occasions he had pulled and twisted enough to cause brief pain, this is almost exclusively a non issue. And certainly less discomfort than having a collar applying constant pressure.Since I’ve been using this collar, I feel I could walk him off leash in many calm, lower-stimulating circumstances, but I don’t, other than around the property and on some hiking trails. On leash he does very well walking loose-leash but will pull occasionally, mainly when trying to sniff something in passing. Still, I’d say it’s been about a 90% improvement in the months we’ve used it.Downside: this 2.25 is definitely more flimsy than the thicker ones offered by HS. However, though I first tried a thicker-pronged HS collar, the prongs themselves were too long. I really wish these lengths of prong had the thicker metal. I have had the prongs slip apart and try collar fall off, twice. Ultimately I think that’s from not having it on firmly enough, but my dog had A LOT of long, thick neck fur. It’s at times challenging to put the collar on snugly with all that fur, as it requires lining up two prongs on one piece with two small prong holes on the attaching piece and squeezing the prongs a bit so they’ll fit. But it’s worth it, and I can do it more quickly nowadays, after some experience.Other downside, my dog immediately knows the difference between when this collar is on or when his lead is attached to his normal collar. As a result his behavior changes a bit. He’s much more inclined to pull if it’s not on him, so I generally keep it on him anywhere we go where he’ll be walking on lead. The positive side, however, is that even without this on, he’s now learned to correct much more quickly with a simple “stay with me” command or even just a clearing-of-throat noise.In sum, this collar has been amazing and my boy no longer acts up on walks, sits more quickly when I stop, and is much less likely to try to jump up the on people he meets on walks. This eliminated the need for an e-collar to enhance training, once other additional reinforcement has been given.

This collar is excellent and genuine Germany Herm Sprenger. The collar is lovely. Not 100% black and looks like gun blueing black. Not a complaint just an observation. I love it and it's easy to remove. Very high quality and will not stretch. Overall very satisfied! 3.2mm is perfect for my 2 year old male German Shepherd with a 19" neck circumference. I removed three links.MAKE SURE IT SITS RIGHT BEHIND THE EARS AND IS TIGHT BUT NOT CHOKING. The martingale section of the collar should be behind the head, NOT on the side of neck or underside of chin, and it will need adjusting often. Also, prong collars NEED to be backed up. Have an additional collar on the dog along side the prong collar. The best option is a flat collar or a dominant dog collar. Attach the leash to both collars. You can also buy leashes made for prong collars and backing up. Prong collars, even Herm Sprenger can break with usage. They're not invincible and you certainly don't want your reactive dog running if one of the links break.

This prone collar works great! It was recommended by my dog trainer for my 90 lb labs. Just a little tug and the dogs instantly respond in a positive way. I also love the black color for my black labs. I highly recommend this quality collar!

Seems like a great product but I returned it cause it was too small for my boxer

Great prong collar, made durable, fit the dogs perfectly, dogs walk much better better with it on and don't pull. Very sturdy and well made.

I hesitated to purchase the collar due to the cost and overall reputation of this type of collar in general. After watching a few Youtube videos, I felt better about prong collars and went with the Herm Sprenger. I wouldn't change a thing--it worked like a miracle on my Akita. It instantly stopped her from pulling my arm off each time she saw a deer or a rabbit or anything else for that matter. SO incredible was the change, I still cannot believe it. Herm Sprenger is the best out there, so don't hesitate as I did.
