Doing chart is accurate. This fits my dog perfectly.

Perfectly designed to my requests!

I requested an orange but the collar I got looks like it's pink.

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!

Ordered a hands free leash and a handle for my service dog's vest. Loved the colors and quality so much I've now ordered collars for her and my other 2 dogs! Definitely check out this awesome seller!

Love these! Third one we’ve bought. Great quality & seller!

Super awesome, wears it all the time!

The collar is high quality and made well. I contacted the seller about a specific length and they were able to accommodate it. Just a note that the black hardware runs off very quickly, but that’s to be expected.

Great quality and durable product!

100/10!!! OMG I can't even!
I love my collar so much!! The owner was super easy to work with. Response time in messages was really fast and she was able to do exactly what I needed!
Thank you so much for an amazing project!

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.

Very well made and better what I thought

Exactly what I wanted. Great quality.

Communication with seller was great. Quality of collars was perfect.

Perfect color and the adjustable size is perfect! I do recommend

Fits perfectly and the color is gorgeous.

Beautiful and sturdy. My guide dog loves it too!

Excellent products all arrived in perfect condition. Thank you!

I love this martingale for my GSD. It looks lovely on her. 🖤

It seems like a good product

Best collars I have ever purchased for any of my dogs. Easy to clean, look great, my 2 standard poodles seem to like them. Love being able to customize it, tons of colors and infinite combinations. Highly recommend

There was a faulty clip I received and their team quickly worked to resolve the problem. Thankful to know you understand safety is a big portion of picking good collar and leash

Love this collar. Works great!

This has been the best martingale I’ve ever bought. It has been through so much from dock diving, to rivers, and in swamps and Dead carcasses it has been roughly 1-2 months and I haven’t had to clean it and it still doesn’t smell!
