How to measure
Buckle Options

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. Made from heavy duty solid brass & zinc alloy hardware. This makes it rust & corrosion resistant. As all coated hardware will show wear overtime, our black metal is PVD treated which produces a durable finish.

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.

This collar is so beautiful and so well made! It looks amazingly beautiful on my Jingles and with the Fi 3 perfect!

Fabulous collars!

I ordered two Fi Series 3 compatible martingale collars. They arrived quickly, are incredibly well made, and I can finally feel comfortable that the collars won’t break if my dogs pull. I also love that these martingales have a quick release for emergencies. Beautiful collars - would buy again!

Nick Alaimo
AMAZING Product and support

Can’t say enough great things about Seaflower company. When I reached out wanting a custom collar that wasn’t even listed on their website, April was glad to do it. The collar is best we have used! Highly recommend and will be ordering more in the future!

Awesome collar

Finally a winner for us. Sexy Beast let us down. I had a Sexy Beast collar and we liked it but my dog had gotten bigger and had simply out grown it. We ordered a replacement from Sexy Beast to go along with our Fi Series 3 setup. Sexy Beast was out of the attachment points but promised to get them to us when they got them back in stock. So we were ok with waiting. And wait we did. And wait. And wait. Three months. Still waiting. We are repeat customers. I told them I wasn’t happy. Asked for a refund. They said they weren’t going to refund our money because of the special order circumstances of each order. Well I got tired of waiting and found a work a round. Another collar from another company. We could not be happier. Lesson learned. Thank you for a wonderful product at a very fair price point.
