Our Integrated Design incorporates the Fi unit into the body of the collar, making it a little more streamlined than our Layered design.

Please note that Fi collar sizing is different from our standard collar sizing. At this time we are unable to make Fi Compatible Collars with Sport Hardware to fit neck sizes smaller than 13”.

⭐⭐⭐⭐⭐ “Great quality material so easy to clean and never gets smelly. Also love the bright red color on my Dalmatians first it looks great! The Fi attachment is very secure and QUIET! We previously had another Fi compatible collar that allowed the fi to shake making it so loud anytime my dog moved or ran around, this one is very secure so is silent!” ~Christina
I absolutely loved the customization, ability to easily clean, & FI collar integration, and really had high hopes, but I'm so disappointed. I purchased on 03/17/2025, received my order about 10 days later, so my pup has been using her new collar less than a month and the grommets have already started rusting. We live in Florida, and she has an active beach bum lifestyle, so I went with a bio thane collar, but apparently the salt water was too much for the grommets to handle, which is so frustrating to pay so much money on something we're not going to get much use out of.
I got two collars for two dogs I am close with and have the opportunity to see grow. They both have their liquid fun. The black one loves snow and the yellow loves to dash through water. Both are sweet boys and their birthdays had passed but got them a few days after the yellow ones birthday. I will be ordering one for my girl once the time comes!!!!
What great birthday gifts for two sweet pups! Thank you Gina for sharing their pictures as well :) We love seeing your new gear in action!
