The Collar For The Adventurous

About our gear: Our Biothane® collars are waterproof, stink-proof, highly-durable, soft to the touch, and feature a variety of color choices! Best of all, a quick rinse under water is all it takes to get your collar looking new again.  We offer two choices of hardware; "Gold (Solid Brass)" and "Silver (Stainless Steel/Plated Brass)." Both are rust-proof and highly durable. 


Collar Sizing Guide:

Our martingales have a chain range of 3 inches. At the loosest, the collar should be able to slide over your pup's head and at it's tightest it should fit snugly. Martingales are not for every dog and proper use of the collar is the responsibility of the owner.  

To measure your pup for a non-adjustable martingale, we recommend using a fabric measuring tape and measuring around your dogs neck where the collar normally sits and subtracting 1" to get the low number in the range. For example, for a dog with a 15" neck the typical appropriate range is 14"-17." This sizing allows room to tighten and pull snug while being loose enough to slide over the dog's head. It is important to note that fit is a matter of personal preference and can vary by dog. It is the buyer's responsibility to determine optimal fit for their particular dog.

Please be sure to double check your pup's collar size!  Ensuring size is the responsibility of the buyer and we do not accept returns or exchanges on products where the wrong size is selected.  It's always best to measure twice just to be sure.


Product Notes:

As with any metal chain, there is the possibility of corrosion that can rub off onto a dog's fur. This is particularly true in climates that are naturally corrosive such as beaches or areas with high humidity. This can become visible on white dogs, or dogs with very light fur. Good chain maintenance can prevent this from happening. Keeping your gear clean and dry after use is important for longevity.



All custom and size-specific products such as slip collars and martingales are not available for returns unless there is a problem in construction with the product. It is the buyer's responsibility to measure their dog correctly. If you have any questions about fit, please reach out before placing an order so we can help you.


General Safety Tips:

  • Inspect your gear before each use for wear and tear that could cause safety issues.
  • Always make sure you are clipping directly to the d-ring and not the tag ring.
  • Never use a leash or collar for anything other than it’s intended purpose. Misuse of gear can lead to safety issues.
  • Never leave your dog unattended while any gear is being worn. It is also not advised to allow your dog to drag their leash behind them on the ground.
  • It is the buyer’s responsibility to determine what gear is appropriate for their dog’s size, strength, and activity level. Mutt Pack is not liable for any injuries or damage that may occur as a result of use.
  • Never use a martingale or slip when swimming.

Return Policy:

We want you to dig your gear as much as we do! If you don't love your order, you can return any items that are in their original packaging and have not been used or worn within the first two weeks (14 days) of delivery.

Please note, we do not allow returns for any BioThane products as these are all custom-made items.

For custom (all BioThane) products, please reach out if you have any questions before ordering. If you would like to preview a color palette we can assist with that to make sure your design is to your liking. It is also important to note that it is the buyer's responsibility to properly measure their dog. Please verify that you are measuring correctly for the item you are buying as we do not accept returns if the wrong size is ordered. If you have any questions about fit, please reach out before placing an order so we can help you!

International (non-U.S.) orders are also not eligible for returns.

new fav collar ever

i got this in white and gold.... Im in love with it truly! such a statement


i seriously love this collar..... i have about 4 colour variants and another one coming! i looooooove these. pretty, durable, stinkproof, waterproof and beautiful

Perfect for my sensitive ear girl!

Clover does not like a tight fitting martingale going past her ears when I take it off... so this adjustable martingale is perfect! I can loosen it before removing and Clover wears a well fitting collar without sizing up!

Amazing product!

I absolutely love this collar. After months of trying to find one in stores I came across this one and is even better than i could have imagined! Thier costumer service is great as well! 10/10 would recommend!

Great Customer Service

I bought two stainless steel martingales in 2020 and finally decided to leave a review this year, I never really let my dog wear them as he’s white and it would rub off on his fur badly. I wasn’t sure if it was a defective chain or what, but I didn’t contact MuttPack just because I thought maybe it was just me so I just didn’t put them on him. After leaving a 3 star review on here I was contacted within minutes and MuttPack has been working with me consistently to figure out what happened, and for that I’ve decided it’s only appropriate and fair to change it to 5 stars for amazing customer service. I know whenever I receive updated chains I’ll be even more over the moon for their martingales, I truly do love the durability and look of MuttPack products and I have two other products from them no issues and they hold up to even my most dirtiest rough dogs! I highly recommend buying gear from MuttPack and if any issues arise be sure to contact them, that should of been my first response.

Hi Julissa! I'm so happy to be working with you to resolve your issue with the chain. I have been in touch with the current supplier we use and sent along photos provided to see what their input is on why it's leaving some smudging on your dog's fur. Since the chain you selected was stainless, this is not something we expect to happen. We have also put in an order for fully customized chains on the off-chance that there is something wrong on our supplier's end. We will be in touch as soon as I find out more! Thank you for supporting Mutt Pack and for your kind words!
