The one I've got him wearing is about 14 year old and is as good as the day I bought it. Cleaning it can be a cnut sometimes though. I soak it in hot water get most of the muck off then use a nail brush with just washing up liquid, scrub like fook, then soak it in hot soapy water for an hour again, scrub again, rinse as best, then bang it in the washing machine in a pillow case, with the dog towels. Bit of a process granted but it's still going strong and has at least another 3 dogs in it ?
