Do you love hitting the trails with your dogs but find yourself always bummed out that your rope or nylon lead or collar is all wet, muddy, smelly or just overall gross after your adventures? Us too - which is why we set out to create waterproof dog gear that is easy to clean, light, and ready for any adventure!

Our waterproof dog collars are made from genuine BioThane® for maximum durability and a look that is as close to traditional leather as you can get, all while being, odor-proof, stain-resistant, and toxic-free. Great for water, land and beer drinking activities. Get the look and feel of leather with our unique waterproof dog collar, while not having to deal with the disadvantages!


Since our gear is hand built, we'd be happy to built the collar to your dog's unique neck size if you share the size in inches in the comment box. We generally recommend that you choose a size that will fit your dog on one of the middle holes, this allows for adjustments on either side. If your dog's neck size falls at the end of the size range, we recommend selecting the next size up. In order to choose the best collar size for your dog, it is recommended to use a previous collar to measure from the clip to the end and use that as a baseline. If you are unsure about what collar size to choose, message us and we'd be happy to help!


You can chose between Gold (Brass) hardware, Silver Hardware or Matte Black. Please note that the Matte Black is more likely to chip and will wear faster but can easily be touched up with an acrylic pen or Sharpie. Our gold hardware is made of plated brass and the black hardware is powder coated.

We use Trigger Swivel Snap hooks for extra durability. These hooks swivel all the way around and are brass plated or black powder coated. 

All of our screws are Chicago Screws and are top-rated for quality and durability.


Hand-wash with mild soap and water. Dry with a soft cloth to maintain the longevity of your new collar. Regular polishing of hardware will minimize tarnishing (patina).
While BioThane is incredibly versatile and repels MOST of the dirt and grime it comes across, please note that it is not completely stain-proof in all circumstances.

DISCLAIMER: Please note that these products are made by hand so there can be slight differences in the small details of the collars, like the hole placement or size, etc. If you have any issues at all with your products, please reach out to us directly and we will make it right!

We use the strongest hardware available at the time, but Evergreen Dog Co. is released from all liability in case of product breakage. We stand behind our products and if something breaks, we will happily replace your product for free! Our collars and leash set are made as aesthetic, easy to clean dog gear and we do not recommend purchasing if your dog is heavy puller/lunger or if your dogs or other dog's safety may be at risk upon breakage


All of our products are proudly handmade in the USA from authentic BioThane! BioThane is cruelty-free, eco-friendly and is commonly used as a vegan alternative to leather.

The hardware that we use on our gear is best in class and truly built for the toughest of adventures. We use Trigger/Lobster snaps for our leashes (the safest on the market) and Chicago Screws instead of Rivets for maximum durability.

Care Instructions

Our products are extremely easy to clean, which is why pup parents love them! Use soap and water with a paper towel or small towel and wipe clean.

Our products are crafted with Chicago Screws which are the strongest the market offers but do need to be checked on occasion after tough adventures. These screws are LOCTITE'd in (superglued) but can potentially untwist over time. If you notice that a screw is coming loose, just tighten it up and you're ready for your next journey!
