About our gear: Our Biothane® martingale 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.

 

Collar Sizing Guide:

Medium: 11-16 inches (+Chain Range)

Large: 15-20 inches (+Chain Range)

 XL: 20-24 inches (+Chain Range)

XXL: 23-28 inches (+Chain Range)

The chain range of brass is 3 inches and the chain range of the stainless steel is 5 inches. 

If you have white or very light-furred dog, we recommend going with a stainless steel chain as the brass chain may patina over time and cause fur discoloration. 

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.  To properly measure your dog's neck, use a fabric tape measure and wrap it around where your dog's collar properly sits. Make sure it is a snug but comfortable fit with no overlap. For martingales, people usually make sure their dog's neck measurement minus one inch is within the collar's range.

 

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 it within the first two weeks (14 days). Please note, we do not allow returns for custom items. If you would like to preview a color palette, please message us before ordering so we can make sure your design is to your liking. International orders are also not eligible for returns.


Size-specific products such as slip collars and martingales are not eligible for returns unless there is a problem due to the construction of the product. It is the buyer's responsibility to 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!

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!

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!
