Waterproof Biothane E-Collar Replacement Strap – 3/4" Wide Blue Bungee Collar for Dogtra, Educator, Garmin – Kona Puppy

This Kona Puppy replacement strap is a waterproof, stink-proof bungee collar designed for e-collars, invisible fence systems, and bark collars. Made from genuine Biothane, it measures 3/4" wide and comes in blue. The push-button cord lock allows quick on/off, and it fits dogs with neck sizes from 14 to 26 inches. It is compatible with popular brands such as Dogtra, Educator, Garmin, and SportDog.

What makes this e-collar replacement strap different?

Kona Puppy uses genuine “adjustable” Biothane rather than the “beta” Biothane found in many collars. This material is softer and more comfortable against your dog’s skin while remaining equally strong and durable. It also holds brighter colors and stays odor-free. The collar is completely waterproof—just wipe or rinse it clean. The bungee cord lock with a push-button mechanism makes putting it on and taking it off faster than a traditional wheel lock, and it holds securely. Each collar is handmade in the USA and tested by Kona, the Chesapeake Bay Retriever for which the company is named.

Compatibility and sizing details

This 3/4" wide strap fits most e-collar receivers, including models from Dogtra, SportDog, Educator, Garmin, and many more. It also works with invisible fence and bark collars. The material is soft and comfortable, ideal for active dogs or lounging hounds. Kona Puppy uses more Biothane than many manufacturers, so the collar feels substantial yet flexible. If your dog’s neck is outside the standard 14–26 inch range, you can contact Kona Puppy for a custom length. The collar is also available in a 1-inch width if you need a wider option.
