Getting surrounded is no fun. My scariest dog encounter was with 4 dogs when I was riding at night. I could hear them closing in on me on both sides, but I couldn't even see them. Fortunately, they let me walk out of their territory. I did call them in. Don't know if it helped, but I didn't see them on that stretch again.
Canine ******* are a part of cycling. The last time I rode, this guy trotted alongside me as I passed his field...
