How a Martingale Works

The Martingale dog collar should slip easily over the dog's head. The dog leash clips on the O-ring. When you give a correction by pulling on the leash, the 2 D-rings come together. The chain is only tight when giving a correction.

This collar should NEVER choke the dog, it just tightens. The tightening plus the sound of the chain helps alert the dog that a correction is needed. Please let us know if you need further instruction on how to use this collar.

Martingales are intended for training and walking purposes only.

GangstaMutt™ Dog Collar Wag Swag Graffiti | Martingale Training

Love the designs and features!

I absolutely had to have these when I saw them, the design style fits our puppy, Vandal, better than any other out there! Her brindle coat and her Wag Swag collars and her leash really highlight each other and look fantastic on her. The magnetic closure is awesome, but she has managed to get it off a few times, mostly when wrestling with our GSD. I do wish the leash had a slightly shorter length available,and/or maybe an extra hand loop midway or closer to collar for control purposes, especially with a learning puppy. The leash is super nice, but very slipper for my smaller hands, which don't have the strength they used to, so any additional helpful options or features would be greato one day! Would definitely buys these all again even though we got a collar with magnetic closure, the martingale collar for walks and the leash to match them both, I may just have to get another design for fun!

We love all your feedback! Shorter leashes and loops are not a problem at Thor's Custom Shop-No extra charge. The link is on our home page or just contact us and we'll get you started with the process. Even the leash you own can be altered to fit you needs.
