Cycling to Cheroh and Dog Chased

I have been cycling regularly to cheroh, alone. So far no problem, but last Sunday morning this mammal chased me.
I was riding back to Raub when I passed a farm not far from Cheroh Aquatic Centre. The dogs that usually stay inside the farm fence suddenly came out and bark at me with its tail up wagging and charging at me.
Adrenaline rush into my head for a fight or flight reaction, at the highest gear I stand on a pedals riding as hard as a can, leaving the dog. Next time I will bring a stick or rattan like what Karim usually do in his night ride.
