Super fast delivery, quality collars for a great price! Contact is so good we’ve been able to switch contact points and go down stim levels. Thankyou!

Very happy with the collar and service which we received, it was first class. The original size L was too small for our Bullmastiff, we were advised to return and adjustments to the length would be made. The lengthened collar arrived within a week and fitted perfectly. Highly recommened.

Absolutely amazing quality, sturdy fabric and obviously the great cobra buckle which is what I needed for my dogs. If your after a quality ecollar strap this is definitely it.

First impressions are extremely strong. Dispatch was fast, packaging was professional, and the collar itself feels properly engineered rather than mass-produced. […] Very impressed.

Every strap we make helps save lives. Every strap we make is built on the lessons my high-prey-driven dog Barry taught me.
Flex Collars creates tactical e-collar straps. Our bungee straps are made from durable military-grade materials that will last you a long time. The flexible element on the collar allows a better grip with the dog’s neck, for better e-collar contact and comfort when wearing the collar.
We are committed to enhancing dogs’ welfare through dedicated e-collar training. And our tactical e-collar straps are a big part of it.

When a recall fails, most handlers blame the remote first. Often the cue never reached the dog, because the receiver slid, flipped or sat in fur. This post explains why contact gets lost, what good contact looks like, and the four checks to do before you leave home.
