Our gear is designed to withstand tough outdoor environments, but it's not immune to damage from dog teeth, nails, or rough surfaces. Our warranty doesn't cover any damage caused by chewing, biting, scratching, rubbing against a wall or crate, or similar actions by dogs or humans. If your dog chews through a Bandana Bungee or BioThane piece of their leash, you can purchase replacement parts to repair at home by contacting us at bandedpines@gmail.com. Please note that our gear is not suitable for use with tie-outs.
