If you order a collar from us, a removable bell is generally included by default, but we can easily omit it from your order upon your request. You will see a checkbox option on every collar product page to "Include a bell" -- just uncheck the box to omit the bell from the collar before adding it to your Cart. Or, you can simply add your request to "Omit the bell" in the "Special Instructions" message box on the cart page, before Checkout.
