  • Made with super heavy 3/4" or 1" BioThane®

  • Low maintenance- Wash in soapy water or just spray off with the hose and, BOOM, it's as good as new. BioThane® is easy to clean in just a few minutes.
  • BioThane® has a soft, easy-to-grip feel & is very pliable even in the coldest weather.

Size Guide
BioThane color combos

Stainless Steel: Known for its strength, durability, & low maintenance attributes. Perfect for all those salty beach adventures, & the best option if your pup is hard on their gear.

Black Metal: A great option for upgrading the look of your collar. However, keep in mind, any coated hardware will show wear overtime. Made from heavy duty solid brass & zinc alloy hardware, which makes it rust & corrosion resistant.

Solid Brass: is just that - brass all the way through to its core. Here at SeaFlower Co, we only use solid brass hardware & not brass plated (which has a much shorter lifespan). Solid brass is known for its strength & durability. It is also rust proof & highly resistant to corrosion. Brass will develop a patina or a tarnish on its surface over time when exposed to the elements, but it can be cleaned and polished to restore its color and shine (Brass-o or lemon juice work great for cleaning your hardware). This patina/tarnish can discolor your white/light colored dog’s neck fur, but can be easily washed out.

Safety & durability is our top priority at SeaFlower Co. We use high quality materials and durable, thoroughly tested hardware for all of our products. Our products are made with ruff play in mind, but no pet gear is indestructible. Please inspect your equipment regularly for any signs of wear and tear & replace when necessary. It is the buyer’s responsibility to determine what gear is appropriate for their dog’s size, strength, and activity level. SeaFlower Co is not liable for any injuries or damage that may occur as a result of use.

Great Quality

Great fit on our dog and solid quality. Really nice that the Fi charger fits in between the main collar and the Fi unit. Our dog is a 35 lb German shorthair pointer and we got a 1” collar to accommodate a name plate but the buckle is fairly large so I think if we had buy again we’d go with a 3/4” collar. Great product though, highly recommend!

We love seeing your pups styling in our gear!
