No, not excessive. The dog was chasing you because it felt threatened. At the same time the owner was not responsible enough to keep the dog contained & probably knows his dog will give chase, all the more reason to keep it contained. The owner deserves to be kicked more then the dog does. There are no such thing as bad dogs, just bad dog owners.

A dog like that comes near me, I don't kick but it does get a facefull of pepper spray. Quite effective. The only time I do not use the spray is when the dog is only running toward or after me with out being aggressive. Then I know it only wants to play or wants attention. Depending on my mood I have stopped I gave the dog attention & of course got the dog off of the street so it doesn't get hit by a car. If a dog is being aggressive & wants to attack the last thing I worry about is if it is hit by a car.
