I had a dog incident last month while on a climb. Luckily I had my video camera recording, so maybe this footage will help others.

I was almost to the top of the climb when I heard barking dogs. I saw three dogs behind a tall wrought-iron fence. On past rides I discovered that making puppy sounds at barking dogs seemed to calm them and sometimes stopped the barking. Unfortunately, this time it backfired The dogs started going crazy and one of them escaped and chased me. I heard the owner yell something so I yelled "Get your dog away from me!", "Hey!", and finally "GO HOME!", all while keeping an eye on the dog so I could jump off my bike and use it as a shield if necessary. Luckily the "GO HOME!" command worked. Either that or I left the dog's territory.
