Really happy with my dog's biothane collar. I've wanted one for a while but hadn't previously seen one with a quick-release fastener - essential for safety. Road-tested it on a walking holiday and it was perfect - dog got filthy, collar simply wiped clean. The riveted dog tag is also great as our boy scratches his neck and eventually wears through the removable ones. The burnt orange collar looks fab on a black dog and the matching lead is sturdy, wipes clean and doesn't get smelly! Excellent products, happy customer.
