How to measure

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.

Very happy!

I purchased the Martingale collar that is compatible with the Fi tracker. Loved the pattern/quality of the collar and my Fi tracker securely attached to it. The fit using the sizing chart for my dog was perfect. The delivery was accurate, I would highly recommend this company.

Very happy!

It fits perfectly, we got it very quickly, seems to be high quality and it's beautiful too. Looks great on my whippet!

The Perfect Fi Collar

The collar design is flawless, surpassing any other well-designed options available, especially for smaller dogs. Placing the fi collar over the band is incredibly helpful, as it eliminates the issue I faced with my previous fi collar constantly breaking off at the tracker attachment. The collar's handmade craftsmanship is evident, showcasing high quality in every detail. Moreover, I was pleasantly surprised by the speedy delivery, receiving my order within a week. The owner was exceptionally responsive and provided valuable assistance throughout the process.

In an effort to reduce the collar's weight and minimize the risk of it coming off, I opted for the martingale style without the buckle. It serves its purpose in this regard; however, I must mention that my dog doesn't particularly enjoy having it put over his head. Despite this minor inconvenience, the collar remains secure and offers peace of mind.

Overall, I am extremely impressed with the flawless design, collar durability, and attentive customer service. It's a top choice for owners of smaller dogs, and the attention to detail in every aspect of the product is commendable. While my dog may have a slight reservation about putting it on, the collar provides excellent functionality and is worth the investment.

Absolutely love it!!!

The collar is custom sized perfectly for my dog's neck. It is durable, well made and beautiful! My dog enjoys playing in the lake and muck and the collar is easy to clean and does not smell after being wet. I absolutely love the collar and plan on ordering more!!
