Custom order requests

We love working with our customers to make that special something for your fur kid. We do try to accommodate custom order requests.

Some things we are not able to make custom
* we do not add handles to harnesses
* we cannot make an item that we would deem unsafe for your pup.
* we do not copy other shops work
* we do not add d rings to places that would not normally have D rings because we have not been able to test them and do not want to put anyone’s pup in harm

How environmentally friendly is your product.

Since we use 100% cotton fabric, polypropylene webbing and plastic and steel hardware, we are very concerned on our impact of the environment.

Cotton is a natural product
Polypropylene has the lowest impact on the environment of any man made product and is 100% recyclable

What is a martingale collar?

A martingale collar is a gentle choke collar that does not use a buckle. The collar slips over the dogs head and then has a tightening feature if they pull. They are designed for dogs that have larger necks then heads like sight hounds (ie: greyhounds, whippets, and Italian greyhounds). Over the years people have used them on other breeds as well instead of traditional choke collars because they are wider and softer. Our martingales have a heavy weight webbing core as well as a dual d ring for tags or to combine with the main d ring to use the non tightening feature.

Do you guarantee your items

What a wonderful question! We absolutely guarantee all of our stitching that holds on the hardware of your item! All hardware is tested before it’s shipped, however over time with use items can show wear and tear which is absolutely normal.

If you experience any hardware issues immediately after receiving your item please reach out.

Please understand we would love to be able to guarantee everything, however each dog is different and some are rougher on items than others, so we can only guarantee the work that we do when we make the item, like stitching.

It is the pet owners responsibility to choose items that are best suited for their personal fur kids.

Unfortunately we can’t cover chewing or damage from normal wear and tear.

What’s the difference between step in and standard harness?

The step in harness goes on by pulling up once the dogs front legs are in, and then clipping over their shoulders. A standard harness goes over their head, through their front legs and clips around their rib cage. Each harness has a photo of what they look like on.

Extremely important Metal hardware facts

Our metal buckles work with a dual spring system, so this means it’s imperative that the male connector has been pushed all the way in to the female portion to ensure that they are locked in. If they are not pushed all the way in it can cause the buckle to open.

All metal buckles are electroplated with the finish and we have tested them on our own pups. They are a quality product but can be damaged by allowing heavy metal objects like heavy tags or tie outs to bang against them. This can cause pitting, chipping, and degrading the finish, or show wear.

All of our rivets are steel and electroplated with the color associated with them.

If you have any questions or concerns please reach out so we can help so you’re happy with your order

Why we use webbing

We use heavyweight and light weight webbing because of the pull strength

Light weight - 1/2” and 5/8” has a pull strength of 300 lbs

Heavy weight - 3/4, 1”, 1 1/2”, and 2” has a pull strength of 600 lbs


We want your pup safe!! Polypropylene webbing is the most biodegradable man made webbing as well as your item will be 100% washable in the washing machine and dryer, it will never lose shape. If the cotton wears your item is still stable.

How do I order a martingale

Ordering a martingale is simple.

Almost all martingales are listed as an upgrade

Step 1. Pick the collar you want in the side release.

Step 2. Add the martingale upgrade, the link should be in the collar item description or it is in the upgrade section of our shop.

Step 3. The size of the standard adjustable and martingale should be the same, make sure to measure the head and neck of your pup.

Step 4. Choose your width and hardware finish


The martingale collars do not have buckles so your choice of buckle color in the side release doesn’t matter, most people just choose the black buckle since no buckle will be added to the collar.

And that’s it!

Added this to the collar of my new puppy it looks great and love that it can’t be ripped off.

I love the gun metal color and the buckle has a great latch on it.


Great quality and answers questions quickly


I've purchased one of these collars before, and I absolutely loved it! I know that being in an area with saltwater will wear down the metal buckles faster, but it's worth it to me. They look fantastic and are so easy to clean! They will forever be my go-to collars ❤️
