Why is it bad that a dog chased my a.s.s.?

I was walking home after work and some kids in a house yelled that a dog was behind me. It was about 10 feet away when I looked back and I then noticed it growling. I then walked faster until a chase began. I out ran the dog a few times by jumping over some bushes but it was relentless to pursue me. It was fun until it started barking. I then decided to turn around and make myself look bigger like a person would do against heiheinas or bears with the use of my jacket. Thus it failed and the dog jumped in the air where I then laid an upper cut and kicked it on the face. The owners of the dog, i presume drove by and yelled at me where I then ran off over a fence. Do you think its wrong that I did that? The dog looked to be a white wolf mix of some sort and about over 3 foot in height.
