Happy to read that you're ok. I'm not a dog expert but I do know dogs well enough to suggest that if the little monster stopped going after you the pepper spay most likely did it's job. I get chased on occassion. Mostly it's just neighborhood labs or golden retrievers who want petted. When I venture on a more rural route the dogs are a little more dedicated to actually catching/mauling me versus just putting on a show. The neighborhood dogs, mine included, really crack me up. The charge toward you and bark like heck, until you tell them what a good do they are. Then they go away happy. Too bad they all aren't so good.
