If you have a mucky dog like our Seamus you can clean with a damp cloth or if needs be machine wash on a gentle wool cycle.
I recommend you take off the collar if it becomes wet on a walk and leave to dry before wearing again. After all, leaving on a wet collar can't be comfy and after a long walk there's always a long sleep!
Harris Tweed is a natural material and will pull if you have a dog that tends to scratch at their collar - please inspect regularly to ensure it's kept at it's best.
*Please note: The aluminium clasps are not suitable for exposure to salt water and should the collar become wet on a walk it must be taken off and dried before the next use. Also, although the clasps are very strong and chosen for this quality, metal I.D tags will dent the clasp if used.
