A dispenser (10) for dispensing a liquid onto an animal is disclosed. The dispenser (10) comprises: I) a primary reservoir (12) to hold the liquid, II) a piezoelectric element adjacent or in the primary reservoir, and III) an external capillary means (222) on the exterior of the dispenser. The piezoelectric element has an inlet to receive liquid from the primary reservoir and an outlet for the liquid to exit. The external capillary means is configured to allow the liquid exiting the piezoelectric outlet to collect or pool in or on the external capillary means and eventually roll from the external capillary means onto the animal.
