Exactly! There's also the significant point that you could get bit in the process of kicking away said dog, and the bite could give you an infection, which all comes back to why we (like most animals) will go very far to avoid a physical altercation.

Basically, fighting shit can be dangerous, even in situations where you easily come out on top 10/10 times. That doesn't mean the fucking chihuahua has a chance.

I've never hesitated to kick at a dog chasing me on my bike. I love dogs, but if a dumbfuck owner lets it loose on the street, I will defend myself with all necessary force.
