Mayerzon Dog Collar, Patented Martingale No Pull Collar for Small Medium Large Dogs with Buckle for Walking Training, Hidden Design, Adjustable(M, Black)

Very happy with it.

TLDR: Buy this collar and change your life!!!!!! My daughter and her boyfriend adopted a shelter dog 1.5 weeks ago. First day or two, not so bad on leash - but we all know the 3/3/3 rule. By day 3, he was out-of-control pulling and EXTREMELY dog reactive (like HE walked YOU by pulling you down the sidewalk, you didn't walk him!!!) If he saw another dog, he went berserk, even though the shelter had said he was dog friendly and had been in playgroup. They were both terribly sick so I was in charge of dog walking for two nights. I'm used to walking 2 big dogs at a time, but their dog gave me a run for my money!!! I walked him 2 miles each night to try and wear him out, but it was the other way around! I had to keep my legs locked and pull back constantly to maintain control, even keeping him on a short leash did nothing. After the second night's walk, I told my daughter this is crazy, he needs a different collar and found this one. The next day (bless you, Amazon, for quick delivery!) we put it on him and it was a TOTAL GAME CHANGER and he was a TOTALLY DIFFERENT DOG! He tried to pull a little the first time we went outside and quickly stopped. The prongs are covered in rubber so he is not getting hurt (honestly, I would think the way he was pulling on his regular leash and choking himself would hurt!) The next day, my daughter's boyfriend conducted an experiment in the morning because it was too good to be true. Short walk #1 before breakfast with the Mayerzon collar - perfect dog, walked nice, barely reacted when seeing another dog. Short walk #2 after breakfast with old collar - in his words, "he lost his puppy mind" and was back to previous horrible walking behavior. He snapped on the Mayerzon collar and immediately back to perfect dog! If I could give this collar 100 stars, I would!

Works good for a 170 lb Great Dane that I rescued and was a fairly big puller initially. Easy to get on and off and I like that it combines the prong type collar but also is adjustable. I find that it does loosen eventually but as he is no longer such a savage on walks it’s more extra insurance for me walking a dog that weighs more than me. The coverage and reflection is also great. Great for walks at night but also doesn’t look as intimidating.

Excellent quality and function. I particularly like the safety feature on the clasp. And because it is a full martingale, with prongs added, there is no danger of the collar falling off because a prong got bent! And the small prong size provides the greatest personal advantage to the handler. I leant it to a student last night and she was very pleased.

Excellent alternative to traditional choke collars. Works very well with out German Shepherd

Amazing collar! My dog listens better and does not pull with this one! The prongs are rubber coated and doesn’t hurt her but she knows she better behave with it on!
