⚙️ Hardware Options
We offer a range of hardware options to suit your needs:
Standard: Colour-coated zinc (durable & great for lakes and puddles)
Upgrade Options: Stainless Steel or Gold Brass – ideal for regular beach use and saltwater exposure. If your dog swims in the sea or regularly gets wet, we strongly recommend selecting one of these options to extend the life of your harness.
