Herm. Sprenger Prong Collar Extra Links, 2.25 mm

Despite merchandise’s tiny size and light weight, the Shipping & Handling is much higher than usual and higher than cost of item. I must have overlooked during ordering. Other than that, it’s an authentic Herm Sprenger at a good price and excellent packing.

Works as advertised with proper sizing and execution. First time using one after growing up thinking they were inhumane - no lesions, no redness, no aggression, no resent coming from my pup. When she sees the collar, she knows it's serious walking/ training time and is visibly excited just like when we put on her front clip harness for longer walks. If you've been considering a prong collar for a while but are worried what people will think of you and your relationship with your dog, just educate yourself enough so you're prepared to educate others. :) Highly recommend these ones in particular for their build quality and rounded ends which are very important.

I have a 95lb, leash reactive male German Shepherd. He's an amazing dog, but pulls on his leash and is reactive to other dogs and delivery vehicles...he knows the Amazon Prime, FedEx, and UPS vehicles all too well! After some initial hesitation, prong collars look medieval after all, I did some research and decided this was the correct tool to use to correct his undesirable behaviors. Before I would put it on him, I put it on myself, applied pressure and was satisfied I wasn't employing a tool that would cause him pain Literally after our first walk, his behavioral problems disappeared. He started to lunge and bark once on that initial use, I gave him the sideways tug for a correction, and he hasn't done it again. He no longer pulls, reacts to other dogs or familiar vehicles and is more attentive to commands. He looks forward to his walks like before and shows absolutely no hesitation in letting me put it on him. I couldn't be happier with the product. I will say that he's a large dog with a thick mane; his neck measures around 18". I had to use an additional two links on top of this collar and the three extra links that came included, for a total of five extra links total. The only "knock" I have is that it isn't the easiest collar to get on, but it's secure and I don't have any extraordinary difficulties getting it on or off. If you have arthritis or any issues with finger dexterity, a collar with a clasp would be more to your liking.

Si el collar le quedó chico a tu perro como en mi caso, estos eslabón es sin la solución

No mucho que decir. Quedan Perfecto con el collar. Con solo dos tendrías suficiente para un perro de talla grande
