Always measure your dog’s neck or current collar before ordering for the best fit.

Biothane used to make our dog collars and leads has a high break strength, and we use the strongest hardware possible for the width of Biothane. If your dog is an excessive puller or you're worried, please get in contact with us before ordering - you may find some peace of mind with our extra strong locking clips.

We can advise and assist on to help you find the right product, but it is ultimately the owners responsibility to ensure they have chosen a suitable product for their dog. 

Whilst every effort is made to ensure our products are made to the highest quality, no product is indestructible. Always check for signs of wear and tear before each use.

Never leave a dog unattended wearing a collar or lead. For our full safety and care instructions, visit our FAQs page.
