Traditional harness sizes not fitting your dog well? No Problem! This extender will increase the girth of your JWalker Harness by up to 6 inches on S/M-XLG and 2-4 inches on Tiny. This will give you the additional girth you need while maintaining the proper positioning.

This piece is compatible with our S/M, M/L and XLG JWalker Harnesses.  PLEASE NOTE!  These extenders are compatible with the latest version of JWalker that were started to be made in January.  Please send us a photo of the sizing label of your harness if you are not sure which version you have.  Thank you!
