This is one of the best martingale collars I’ve ever ordered! The sizing is excellent not too big and was the perfect fit! For a working service dog this is perfect as it holds its size well!

Perfect and exactly as described.

Love our new collar, as someone with a service dog I like that there’s an extra d ring for tags or if you’re someone who uses a bringsel so I really appreciate that!

Very well made and better what I thought

Exactly what I wanted. Great quality.

Biothane Leash Wrap Alternative, Custom Text, Optional: Twist Lock Carabiner

I am extremely picky when it comes to my service dog’s gear and for the first time ever I have no notes. The workmanship is exceptional with high quality biothane that is both thick and vibrant and attachments/fixtures that are strong and secure. The final product looks incredibly professional and I feel confident using it on both with and without his vest. Incredibly versatile and worth every penny.

The buckles are very well made and goes great with my herm sprenger, I have been waiting to make a review to see how they hold up and it’s been a few months now and it’s holding up great! (The photo is just for show, I always have the buckle in front so that the free space is where my dog’s throat is.)

I love this traffic lead and I use it all the time, it’s very convenient to get control of your dog or in my case get my dog closer to me when we are walking in areas with a lot of cars. Its way easier than just tightening your leash since all you need to do is grab the handle.
