Darkyazi Durable Pinch Collar Stainless Steel Dog Adjustable Pet Training Collar for Medium Large Dogs (Medium (Pack of 1), Silver)

I have used spike chokers on my Samoyed in the past. So I know what to expect and this has never happened before. There is something wrong with the quality/material used in this metal that it is causing this discoloration. Never seem this happen before.

I bought these for 2 dobermans. They fit well and have curbed their pulling behavior. Both sets came with caps for the choker points you have to put on yourself. Fit great and quick. Very happy with product.

I am a fan of using pinch collars for my larger dog breeds. It's the best way i've found to get them to stop pulling and prevent them from damaging there trachea.This has shar edges on the ends of each prong that left my dog bleeding!! It waa very difficult to remove it from the dog as u needed to remove a prong by squeezing the metal which I was the only one in my home strong enough to get it off and for me it was even hard.I ended up trashing this collar and purchasing the REAL one, from Petco. This on has clean rounded edges, it was easy to put on and remove via a squeeze clip and was fairly priced!this was a waste for money and hurt my beloved furbaby!

I have used these collars to train dogs for many years. I decided to purchase this one due to price and the misbelief that they are all pretty much the same. WRONG. I sized the collar to my dog (lab/heeler mix puppy) and went for a short walk. Everything seemed fine. However after about a week of use, and longer walks, my dog began pulling hard because of a neighbor's dog barking at the fence. When I gave a sharp pull, to correct the pulling, she yelped. The rest of the walk was uneventful. I gave her a bath a couple days later and found a large scab on her neck. It was in the shape of a tear drop. I checked the collar and sure enough, the prongs have not been ground smooth, but rather are just cut pieces of wire with sharp edges. Instead of tightening, some grab the skin and in this case tore it. DO NOT BUY THESE! They are cheap, because they are cheaply made.

Good collar, but the very first time I used it, i lost the link that is used to attach/detach the collar, so had to buy another one. You have to be careful or you'll lose that link and then can't use the collar.Update: ordered a second one and same link fell out. I would not recommend buying this collar

First of all it was too big for my dog, she freaked out and got loose and I had to chase her around the yard. I returned it to Amazon, got my refund. Now months later Amazon claims they never got the collar and I’m getting charged for an item I’ve already returned. Scam!!!

This collar is almost impossible to add or remove prongs to adjust size. I have to use pliers each time I put in on and take it off my dog bec0uase it is so stiff.

Comes with rubber fitters to make sure it doesn’t cut the dog. I trained my dog in a day to stop pulling with this. (100lbs+)

Purchased this prong collar after my previous prong collar had started to change collar unfortunately this prong collar was no wear near the quality of my first one prong collar must be slipped over dogs head to put on or it will just break so it your dogs head is to big to fit the prong collar on without poking them with it this collar is no good to use

The prongs are way too oversized. The smaller prong is from my old collar that is a true 3mm. Not sure what this size prong would be used for as I use the smaller prong for a 100lb dog. I am not surprised that this is grossly oversized as I have been tricked like this before from a well know pet store. Best place to buy prong collars is the farm and tack stores, and in person. I will be returning.

Poor quality chain, can’t unclamp them with your fingers like your supposed to to remove them or to take on and off of dog

Product huge and cheap metal
