Seaspriter's advice is very good, but I will add one suggestion; be sure to use pure neatsfoot oil, not the commonly available neatsfoot oil compound. The compound will contain mineral oil and other things that are not the best for leather.

Pure neatsfoot oil is also good by it's self. Apply a light coat, adding more later if needed, too much of anything is bad.
