Thinking for the technique again. If you are cycling the same route every time, and the dog is there every time. Won't the dog be coming after you for food since you have fed it once? Maybe if you just cycle past, it might not even be chasing you. I remembered once when I was cycling, and there was a dog along the path. I went past it at quite some speed and it was scared. I was lucky it didn't come chasing after me.
