Perfectly Purple

My pup loves her new purple collar! It is indestructible. (Beleive me, she tries!) And best of all, she thinks she is quite beautiful with it on.

Good collar but could be better

I really like this collar. It fits the Fi device and it is easy to put into place. The collar is ok to clean (takes a while to dry) and it is true to size that I ordered. I wish there were more options for the Fi3 collar… I would want a 2 inch with the handle that included the Fi3 build in like this one. There is on option for the Fi3 with a handle. Ideally this collar and all others would have a tag loop. I would have given 5 stars if it had a tag loop and/or option for a handle.


Sent wrong size and were going to charge me for the exchange. Bad customer experience.


Very nice
Fits great
