To prevent chafing, make sure to choose a properly fitting, breathable, and comfortable harness for your K9. **

Applying a soothing ointment like zinc oxide or petroleum jelly can help alleviate chafing from riding.

Regular cleaning of tack, proper fitting of the girth, and using a protective pad or sleeve can help prevent chafing. **
