My wife wants me to leave work early and take the dog for a walk today. Is it okay with you?
散歩 is "a walk." Make that into a verb and you have to go for a walk or to go for a stroll.
This is a jukugo word that uses the on'yomi readings of the kanji. You should be able to read this on your own. It will help to know 散歩 as well.
