Due to the robust quality of both fabric, leather and parts our collars remain beautiful. The leather surface can easily be treated with saddle grease, the fabric surface with green soap. Does your dog like to swim in the sea? We advise you to remove the leather collar because leather and salt are not a good combination. Has the leather been in contact with salt? Then rinse the collar with tap water and let the collar dry at room temperature (not in the sun). A post-treatment with saddle grease or leather balm is highly recommendable. You can clear our fabric collars with a wet cloth. If the collar is very dirty, you can put it in the washing machine, in a washing bag (wool wash program). Don’t forget to remove the pendant with shells and a possible nameplate.
