- Rachel A.Verified BuyerI recommend this productRated 5 out of 5 stars10 seconds agoPerfect Attachment!
I love this attachment because I can put it on my dogs’ other collars and they don’t have to wear too many collars on their walks. I’m really picky about the collars I use and the Fi never had anything to suit my uses. Now I can buy collars from my usual vendors and just put the Whistles on whatever collars my dogs are wearing!

Too long of the strap. But if you wish to cut you would cut the Velcro part so it wouldn’t stick.

I purchased this attachment to replace the original health one...come to find out it was the wrong one. Upon contacting the company to buy the correct product they sent the proper attachment and all is well!!! I love my Whistle Health. Its exactly what I need to monitor Henry wellness.
