Gently clean with a soft cloth and clean with a leather cleaning product. Afterwards always apply a caring balm or grease. If the collar becomes muddy, then clean with a damp soft cloth and allow to dry naturally, stay away from direct heat. Remove the collar if your dog is playing rough, swimming or scratching excessively. Advise is to not let your dog wear the collar when swimming in the sea. If your Staffordshire Bull Terrier collar has been in the sea rinse it with tap water and let it dry naturally. Treating it with a caring balm/grease afterwards is always a good idea.
