Purchase Herm Sprenger Snap On 20" - 3.25mm

I tried every training device out there on my Shepherd before I tried this. We tried the choke chain, the Halti, Gentle Leader, no pull harnesses... The dog has dog aggression issues and she would lunge- growling, barking, and snarling, at other dogs and sometimes people when we walked her. It was hard enough walking just her, but we have a second dog too. The other dog will also lunge if the first one does, and together, that's 160 pounds of dog lunging on the leash.

The big dog, in addition to being aggressive, is also sensitive. She has been known to yelp if you touch her ears or scream if you accidentally step on her foot. I thought this collar looked atrocious, but I knew I couldn't have my dog lunging out of control. It wasn't a safe situation, and the dog needs exercise. I tried the collar on myself before I put it on the dog. With the collar around my thigh I gave a hard jerk- much harder than I would ever correct my dog. It doesn't hurt. It squeezes and pinches all the way around, not abrading the skin at all, but I wouldn't call it a pleasant sensation. I had to remove several links from the collar to fit it right- it should sit at the top of the dog's neck, not at the bottom. The quick release makes it much easier to get the collar on and off than having to snap the links apart every time. The points of the prongs are rounded so they are not actually sharp. Some other brands do have sharp edges and metal burrs, which is why Herm Sprenger is the brand to get if you need a prong.

The first time the dog wore the collar she lunged in her usual fashion- just once. She can't muscle through the correction with this collar like she could with the Halti or the choke chain. She didn't yelp but she immediately stopped barking and growling. Wheras before she would "zone in" on whatever she was barking at and basically ignore us, with this collar, she is definately always aware that we are holding the leash, and it's possible to get her attention back even if there's a dog very close by. I can hold her right at my side with very little effort. In fact, with this collar, I can walk both dogs at the same time, although they outweigh me by 30 pounds. The only bad thing about this collar is that some people will give you very dirty looks when you use it. Some people think it's abusive, or dangerous, or unneccesary. For us it has allowed us to give our dog the exercise she needs, without hurting her or putting others in danger.Get more detail about Herm Sprenger Snap On 20" - 3.25mm.
