P.S.I. Imports DPS6423 Chrome Plated Prong Training Dog Collar, Small 2.25 mm

we have two wheaten terriers with VERY strong neck muscles and strong terrier hunt instincts. After working with an excellent dog trainer trying various methods to teach my first of the two dogs not to pull, she gave us a Sprenger collar, a heavier weight version. It works wonderfully! I tried to use it just for training purposes, however after my 35lb dog pulled so quickly that I ended up with a shoulder and rib injury I knew this collar was a must.When we rescued our 2nd dog, we discovered her desire to chase squirrels and birds necessitated another Sprenger collar. I found this lightweight version at Amazon and knew I wanted it over the medium weight one for my first dog who still isn't a fan of the collar. He is much happier with the lightweight version.My only reason for the 4 stars is that even though I measured his neck, the sizing is a touch too small. Unfortunately, the extra links aren't shipped through Amazon, so I'll have to pay too much to have a couple of links shipped to me.

I found this "prong" or "pinch" training collar to be of very good quality, much better than other brands that you may find at your typical pet store. The tips of the prongs are rounded off so as not to dig into the skin of the pooch's neck. I actually tried this collar on myself, and found it to be NOT uncomfortable, to the contrary of many vocal dissidents against prong collars as being "barbaric" for the pet. The key to successful use of this as a training aid is to properly fit the collar high up on your dog's neck, just below the ears. Adjust it tightly enough so that it doesn't slip down, but not so tight as to pinch the dog's neck without any added pressure from the leash. You MUST measure your dog's size properly using the circumference of the neck just below the ears. The links are removable and can be added or removed to adjust the size of the collar. You will probably need to add extra links if your dog's neck is at 12" or larger, since the measured length of the Sprenger collar is 14" laid flat and doesn't account for the smaller circumference when measured from the tips of the prongs themselves. It may be more cost effective to purchase two entire collars that to buy extra links. The slip chain part goes on the side of the dog's neck, not the top. There are two ring's on the slip chain part, a larger "dead" ring, and a smaller "active" ring. Connecting the leash to he dead ring limits the tightness that can be applied to the prong collar, while use of the active ring gives a stronger and quicker correction. Correction is accomplished by a quick but gentle sideways snap of the leash. The correction is supposed to feel similar to a corrective nip that a mother dog would give to a puppy. This training collar is NOT meant to be pulled on so that the prongs constantly dig into the pooch's neck. I have this collar for training my 65 lb pit bull, and it works great. You really don't need a "stronger" collar with larger prongs unless you have a large dog that really is stubborn and pulls hard. Remember, prong collars are for training purposes only and should not be left on you pooch longer than needed for the day's training period. Use a regular collar for fashion and identification purposes.

I purchased this and what I received was NOT a Herm Sprenger Prong collar. It was an inferior prong collar that has black plastic nubs on the tips (the tips are unfinished, rough, and not rounded) of the prongs and does not say Herm Sprenger anywhere on the collar. I purchased a second one a few weeks later and such a peculiar thing happened... I received an actual Herm Sprenger collar. So, please beware of this seller. You may not get what is described. Will not buy from again.

This product is worth the weight of my dog in gold. My corgi mix is about 1 year old. She is very energetic, very willful, and she thinks its her job to walk me on the leash, not vice versa. As soon as the leash goes on, she starts pulling with all her strength. She pulls so hard she suffocates herself. So you can imagine that walking her has not been very enjoyable. I looked online for a solution and everyone recommended stopping in place whenever your dog pulls on the leash. The problem is, my dog never stops pulling. We never got past the front driveway for several weeks. Maybe this might work with a less willful and energetic dog, but it didn't work with mine.So I started looking for a prong collar. I wasn't very optimistic, because if my dog doesn't mind choking herself on the leash, what's a few prongs in the neck after all? The Herm Sprenger collar came highly recommended so I ordered one for her. I put on the collar, leashed my dog up, and we set out. It was like I had a new dog. She started pulling like she usually does, but immediately stopped when the collar tightened. She gave a small yelp, but since then, she has stopped pulling completely. Our walks are so much more enjoyable.The collar itself is well constructed. You have to undo one of the links to wrap get it around the dog's neck. After you do it a few times it gets easier, but it can be a little difficult if your dog is squirming around. But the design does allow you to expand the collar if your dog grows or you want to use it on another dog. It's a tradeoff. The collar tightens very fluidly when your dog pulls, which is nice to see. The collar seems very sturdy, and I don't have any fear of it breaking or coming apart on our walks.Overall, this is the best item I have ever purchased for my dog. It's allowed us to go on more walks, and I don't have to dread taking her out on the leash. I'm hoping after a year of using this collar, I'll be able to stop using it, but we will see how that goes.
