Prong Collar for Dogs, Adjustable Size Dog Training Collar Dog Pinch Collar with Quick Release Buckle for Small Medium Large Dogs(Packed with Two Extra Links)

It's good and sufficient. The plastic nibs fall of and don't work but the collar itself is good.

I have carpal tunnel in both my hands so standard prong collars are very difficult for me to take on/off. The quick release buckle is significantly easier to use and I love that it functions as a trachea guard as well. The bare tips are nicely rounded so they don't require the covers provided but I find them helpful for keeping the collar from sliding down your dog's neck. Over all it's very well made and easy to use.

I didn't have this for a very long time when the clasp (a cheap metal) broke. The collar isn't any good without the clasp.

Makes it much easier to co trol my dog when on a leash

So my 5 month old Rottie is over 60 lbs already, and he was pulling like crazy and has become stronger by the day. I’m only 110 lbs, 5’2 and I was using all my strength to keep him in line during our walks. I ordered this collar and I can tell you that after only 2 uses, this is a GAME CHANGER! My Rottie stops pulling as soon as he feels the resistance and I find myself using no force on our walks. Our walks are now effortless and my arm is no longer throbbing after 5 min walks lol I love this thing, highly recommend! Also, don’t buy a large, I actually had to take off 1 link on the medium sized collar and may have to remove 1 more because it starts to slip a little.
