Herm SprengerDog Training Prong Collar with Quick Release Cliclock Buckle and Swivel Ring | Adjustable Length Stainless Steel Collar Made in Germany for Large Dogs up to 20" Neck (3.2mm Prongs)

Collar is good however different from the image shown on amazon site

I had a prong collar from another company. It was heavy, bulky, hard to shorten and had cheap stamped metal pieces. The Herm Sprenger is much lighter, smaller and well made. The snap makes it easy to put on. Worth every penny of the purchase price.

Our 54lb 14 month old Goldendoodle was a strong puller, even for my husband. I tried many different collars and was hesitant to try a prong, mainly because I did not understand how to properly fit them and how they worked. Our trainer recommended the prong (after my many collar purchases to try & avoid a prong). In diligently doing my research I chose the Herm Sprenger. Be very selective on quality, don’t be cheap, learn how to properly fit & handle your dog with one. I was concerned about how they work and watched a lot of videos on proper fit & use along with our trainer. This was a game changer, she is doing great! This is a training tool and will not be a forever collar. This tool helps teach her to understand what the pressure means when she pulls on leash. She does great with it, it is comfortable for her and when properly fitted will not slide down, around or be near the dogs trachea area. Your dog will learn to walk loose leash and they will self correct with gentle pressure NOT choking. You DO NOT pull on your dog they will self correct. We got the quick release for easy on off, 2.25 cm prongs, stainless steel and size small worked wonderful on her. MUST be fitted behind ears & jawline not where normal collars ride. We also bought a back up attachment to attach to her regular collar or harness in case prong collar released so you do not loose your dog. Watch for the real Herm Sprenger made in Germany prongs are nicely rounded and smooth unlike sharp after market. The Herm Sprenger is more expensive but so worth it! Highly recommend, make sure & educate yourself how to fit & use. Lots of good dog trainers on YouTubeteaching on use & proper fit.

good quality training collarbut please learn proper use before using on your dog

I like the fact that these are adjustable. I now own two of these collars. My older medium sized dog will not get any bigger and two or so prongs have been in storage. My new pup has a medium collar with many of thr prongs removed but she will be a big dog when she grows up and I may use all of the prongs then to fit her size. Right now this collar is perfect and walking the two together is significantly better. I will do this! The pup took to this right away. She wasn't so about it in the very beginning but when she knew we were going out front and for a drive in the vehicle she could barely wait to have me put it on. There was no whimpering from it being on her. None of my dogs have ever whimpered from this type of collar. This collar is seriously very humane as well....mimicking the pitching correction a mother wolf would do to correct her pups. The choke collar by comparison takes a skilled handler to use it properly and I am not as skilled with that kind of coordination.We're off and training now. A kind of freedom for us now because walking is going to be fun and safe and under control.
