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.

Well crafted collars and great customer service

If you are considering a SeaFlower collar, this is your sign to go for it! My dog's head is the same size as his neck, which is right between the M and L measurements. When I contacted April to check on sizing, she was fast to respond and offered to make an in-between size at no extra cost! I was so impressed and grateful for the individualized support, and the collar fits perfectly.

Perfect for my escape-prone dog

This is my second set of SeaFlower collars as I've updated to the new Fi series. I love that it's a buckle martingale. I have an escape-prone dog and need a martingale with an emergency release. I also love how the whale shark print looks against her dark coat.

Awesome collar. Well built and looks fantastic! I’d work with Seaflower again!

Best fi compatible collar that ticked all the boxes

After only a few months with the standard issue fi (fi 2) collar my dog ended up with hot spots around her neck. We assumed it was from the device against her skin so we only used her collar when she left our property. Not the best was to use a GPS collar. So i started looking for an alternative.
Glad i chose seaflower. The designs are super cute the collars are well made and we were able to customize a collar to be a buckle martingale with the device over the band. Ticked all the boxes for our pitbull mix. We will be looking for some back ups so we can change them out if they need to be washed. Best decision ever.
Also was excited while ordering and forgot to use the promo code i got for signing up for emails. Emailed them right away and they applied it to my order. Such a great company.
