Canine Equipment Technika 1-Inch Webbing Martingale Dog Collar, X-Large, Black

This is an extra large collar and needs to withstand the pull of an extra large dog! I recently adopted a mastiff who I am teaching not to pull on a leash. She hit the end of the leash wearing a CE martingale, and the metal hardware bent and released her from the collar. She is only 105 pounds, hardly an extra large dog. The hardware needs to be much heavier gauge metal so that the dog can't bend it by pulling.

Well after only a few walks this collar broke (see the picture I uploaded). I was walking my Great Dane (only 100lbs small by Great Dane standards) he is very good on the leash rarely pulls. Then the little metal piece pulled apart. I was left holding my leash with the collar but no dog. I have used this design in the past with no issues but the metal clips are just too weak for any large bread dog.

Bottom line... I would not risk this on my pet... if he broke free and was a runner well who knows what could have happened.

I have a 2 year old Rottie mix who loves her daily walks. My brother gave us this as a gift after he had success with it on his American Bulldog. After trying several other martingale style collars, this one has definitely been our favorite. We have had this for 3 weeks now and are very happy with it. We got an XL and the fit is good and I have not had any issues with it as of yet. Our dog typically fights and pulls whenever she is not comfortable in her collar, as she has a very thick Rottie neck. But she seems a bit more calm on her walks to this point. I reccommend giving it a try as both our dog and my brother's dog have had success with it.
