Care information

While biothane is durable, our hardware can take a beating. Please limit exposure to harsh elements such as salt water to ensure a long life for your gear.

To clean your products, a little soap and water should do the trick. Stubborn stains should come off with a little rubbing alcohol.

Brass hardware may tarnish over time and can be brought back to life with ketchup or other brass polishers.

Always beautiful

I have several collars and they’re all gorgeous and wonderful quality, my pup is rough on her equipment and these hold up great! I love that they’re easy to clean too!

Beautiful option for the Fi tracker!

I got this collar with the crystal upgrade for my dog and it is so pretty! I was looking for a martingale option for my Fi and this ended up being perfect. Alex is easy to work with and I would definitely recommend this collar.
