A new dog appeared yesterday on my favorite road route. Since I am not an "animal person" I would love some advice on interpreting his behavior as well as how to proceed in the future. Since he ran in front of me I slowed way down,...but he did not growl or bark so I kept riding slowly. He trotted along next to me for half a mile and then abruptly turned back. My main concern is for the future, wondering how to know if it is safe to zoom by or if I should just assume I am stuck slowing down at that spot from now on (pooey...) He was a boxer if that breed has any tendencies that explain his behavior (google was not much help there....)
