Made: Maryland, USA, from US-sourced materials
Sizes & Widths:
- Small (S): 7 to 10.5 inch neck, 5/8 inch wide
- Medium (M): 10.5 to 15 inch neck, 3/4 inch wide

DESCRIPTION
Bold blue & orange biothane, tough enough for wet dogs. A waterproof dog collar in coated biothane that mud and lake water wipe off in seconds. The blue & orange colorway runs through the coating rather than being printed on top, so the color stays vibrant through years of walks, swims, and rolls in things you don't want to think about.
Cut, punched, and assembled by our team in Maryland from US-sourced biothane. Solid brass and nickel-plated hardware chosen for weight rather than the cheapest option. Four sizes: small (7 to 10.5 inches) at 5/8 inch wide, medium (10.5 to 15 inches) at 3/4 inch, large (15 to 19 inches) at 1 inch, and X-large (19 to 25 inches) at 1 inch. Measure snugly against the skin, leave two fingers of room.
Biothane will not absorb moisture, so a wet dog does not become a smelly one. The strap holds its shape rather than stretching out after a wet season, and the sealed edges will not fray. Add a matching leash in the same blue & orange, or one of our engraved tags to complete the setup. Ships in 2 business days from Maryland.

FAQ
How do I choose the right size?
Measure your dog's neck with a soft tape, snug against the skin rather than over fur. Small fits 7 to 10.5 inches, Medium 10.5 to 15, Large 15 to 19, X-Large 19 to 25. Between two sizes, size up for a growing dog and down for one who has stopped growing.
What are the widths for each size?
Widths scale with size for comfort. Small is 5/8 inch, Medium is 3/4 inch, Large and X-Large are both 1 inch. Wider straps on bigger dogs spread pressure more gently on dogs who pull.
Is the collar waterproof?
Fully waterproof. Biothane is coated polyester webbing with no fibers exposed to absorb water, so a wet collar comes out of a lake at the same weight it went in. Wipe it clean with a damp cloth and it stays fresh.
Will the collar smell after swimming?
No. The whole reason waterproof biothane exists is that fabric holds moisture and bacteria, and biothane cannot. Dogs who swim and roll in unpleasant things come home with a clean-smelling collar.
Can I attach a tag to it?
Yes. The D-ring takes a standard split ring, and any tag attaches in seconds. Our engraved tags come in four shapes and four finishes if you want the metal to match the buckle.
What if the collar does not fit?
Reach out and we will sort it. Dogs' necks are hard to guess and sizing charts only get you so far, especially on dogs with thick coats. We are happy to help with sizing or exchanges.
How long does a biothane collar last?
Years of daily wear is normal. Biothane resists cracking, fading and stretching, and will not stiffen after repeated soakings the way leather does. Hardware and fit are what to watch, so check both every few weeks.
Is biothane safe for dogs?
Biothane is polyester webbing with a protective coating, the same material used for horse tack for decades. Reactions to the material are rare. Most collar irritation comes from wet fabric held against the coat, which is what a waterproof biothane collar avoids.
Can I use this on a cat?
The smallest size starts at 7 inches, which fits some cats, but these are built for dogs and have no breakaway safety buckle. Cats need breakaway collars for their safety. Buy a proper cat collar and add one of our tags to it instead.
Where are these made?
Every collar is cut, punched, and assembled by our team in Maryland, from biothane sourced in the US. That is unusual at this price, and it is what lets us stand behind consistent hole spacing, sealed edges, and quality that does not vary batch to batch.
Do you ship to Canada?
Yes. Orders to Canada arrive in 2 to 5 business days after shipping, and shipping is free on orders over CAD $50.

1 waterproof biothane dog collar in your chosen size and color

I wanted to love this collar because it's made in the US and it's easy to clean. I measured my dogs neck and ordered the correct size per the guide but there is too much excess. I was going to over look that but 2 weeks after wearing my pups neck has become very irritated and broken out where the metal is. 2 days after taking it off and her neck is still red with little sores.
The color was nice and bright easy to clean. It does not hold moisture like the cloth, canvas collars do, therefore, it does not get a moldy we smell.
This is a very nicely made collar. The hardware feels nice and hefty and it looks great on! My 80lb golden retriever wears a large and it fits him perfectly. Very happy with this purchase
We got a medium last summer for our dog and it was just big enough, we planned to return it but Chewy reimbursed us instead. Our dog has grown and we needed to go up a size this summer but the difference between medium and large is significant. Large is a lot heavier and there is a lot of excess collar.
