Herm Sprenger Prong Collar for Dog Training | Micro Prong Stainless Steel Ultra-Plus Dog Collar | Assembly Chain Training Collar for Smaller Dogs | Made in Germany - (1.5 mm, (Neck Size Upto 9.5"))

I wish I would have discovered this years ago! My 5-year old Golden Retriever is a continual puller and makes it very unpleasant to go on walks. A friend recommended the Halti which goes over the muzzle. I was not comfortable with that, even though I know it works really well for some dogs. I decided to try one and my dog lost her mind on our first walk wearing it and got her paw caught in it while desperately trying to get it off. Being a horse owner in the past and being familiar with this brand's excellent products, I bought it as a last resort, along with the clasp that is sold separately. It was extremely frustrating trying to figure out the clasp which you must slide to one side and then pinch to release (I wish the company would give better instructions/videos to make this an easier task.) It has been a lifesaver now that the clasp issue is solved and I highly recommend!

Update on this as my Aussiedoodle young dog FINALLY gets my drift to behave on walks. Last collision with her (without the collar) sent me to the ER and follow-up with Ortho Dr. My knee suffered severe soft tissue injuries but my knee implant not affected and several weeks later of R.I.C.E. can feel her coming back.

This prong collar is among the best that I've ever bought. I have a shih tzu, who’s the epitome of "I can't take you anywhere" he's constantly hostile toward other dogs, or just barks excessively. But after purchasing this, he is now walkable. I’m so glad the dog trainer recommended it.

We got the collar for our 7 mos old lab puppy who pulled insanely during the walks. Nothing worked. We saw the reference to it in one of the YouTube video. The moment we put the collar on her, she became a different dog, behaving like a “lady”. The walks are enjoyable now. Before they were a torture. Been a month or two and the difference is huge. So happy we got it!

I have a male german shepherd and when I tell you he pulls, believe me he pullsss. Once he comes across another dog, there's no full control of him. I kept contemplating about this collar and decided to give it a try. Well, best decision since I noticed the difference right away. When he would see another dog, I would do a slight pull and he would automatically listen. I used little to no strength throughout the whole walk which made the walk enjoyable. (: My only issue is I struggle to put it on and take it off. :/

Good fit and quality. I bought just a little small and got a few extra links. Totally changes control of somewhat uncontrollable dogs. You don’t have to hurt dog…just get there attention and let the dog know who is in control. I follow Robert Cabral for training.

I am not sure that I have ever written a review for a product. If I have...I am not sure when the last time I did was. I was feeling pretty confident about my dog training skills. Between gentle-leaders and no-pull harnesses, consistency, and positive reinforcement, I have trained 5 previous dogs to walk calmly on a leash. Four of those dogs were all at once. "look at me and my skills!" I thought....walking all four of these lab-mixes all at once. For years. Calmly. And then... Bodhi (an 8 month old 65 lb golden retreiever/husky mix) came into my life and humbled me almost right onto my toosh onto a road with traffic. Because a dog was across the street with a bell on his collar and the excitement was just too much! First I used a no-pull harness. Then a gentle leader. Then a trainer I worked with in an obedience class recommended a martingale. It was useless. The gentle leader I used was the most effective, and that was still minimal and I felt like I was hurting him during corrections. We walk twice a day and I dreaded it. I thought I was a calm, cool dog owner. I fet like I was turning into a crazy person alternating between corrections and positive reinforcement on our walks. Although, my 14-year-old lab mix was loving all training treats she was getting alongside every attempt I made to reward Bodhi for positive behavior. I was convinced for months I was doing something wrong and feeling guilty and more defeated with every youtube video I watched about just needing to figure out better communication with my dog. I was on the verge of breaking the bank and sending him away to a 2-week board-and-train program. I heard prong collars were inhumane, but when I got desperate, I started to research them. In just ONE DAY, the results were immediate. And boy wagged his tail throughout the whole walk and just looked up at me when we saw another dog and gladly took treats instead of pulling. I watched multiple youtube videos about using this correctly before trialing it and introduced him to it in the backyard first. It feels sooooo much more humane than constant corrections and stopping and changing directions throughout our walks. It was calm and easy and I felt like ME again. The corrections were drastically less and we all were happy and calm throughout our walk. SO HAPPY I TRIED THIS. Nothing inhumane about it. And good learning for me about recognizing different methods for different dogs. We look forward to many calm, long walks in our future!

Arrived as advertised. My dog trainer suggested to use this when I put my Boxer dog for rehab sessions with her. After the sessions were done, she suggested to continue using this when I’m walking the dog. It mimics the bite of a mother when she wants to pacify or control the behavior of her puppy. It looks like a weapon of terror but it doesnt hurt the neck or the dog, I used this whenever she gets fixated on a cat crossing or another dog she deems threatening. I pull up the chain and flick the strap to get her attention diverted and continue walking. It works very well.
