This listing cannot be purchased individually, it must be purchased with a collar.
Note: the sizing change with adding this option
The Fi changes how far the collar can adjust, so keep an eye on sizing. The sizing you select on this listing is the size we will make your collar.
The original fi device connectors are 1" wide, so for anything other than 1" wide straps on an original fi collar we'll use biothane to connect it together (i.e. for the 3/4" & 5/8" widths)
The new Fi 3/3+ has 1" or 3/4" connectors, so we'll use those for those widths, and we'll use biothane to attach 3/4" connectors to a 5/8" strap for our smallest size.
No collar is indestructible, customers should check for wear and tear of their dog's collars and replace when necessary. It is the full responsibility of the customer to determine the suitability of the collar for their pet.
