Biothane:
My collars can get really muddy and they are really easy to wipe clean and put straight back on. If things get really bad (if your dog likes to roll in poo) they can be disinfected.

Waterproof, stain, odour & dirt resistant ( simply just wipe down to remove dirt )

Leather:

our leather collars can be used in all weather, though leaving a leather collar on a wet dog or bunched up in a bag overnight is an invitation for permanent stains and potential mould or mildew. 

Please also note We highly recommend your dog is never left unattended wearing their collar for safety reasons. We cannot be held liable for any injury sustained whilst wearing one of our collars.

We test every collar and buckle and do not sell anything we are not happy with, however we would recommend using with caution in dogs who pull a lot on the lead.
