I bike 2-3 days a week and a dog on the route has been getting increasingly aggressive. Yesterday, he actually hit my rear wheel. It took me a rotation to regain control, but it didn't seem to hurt the dog.
Today I took some pepper spray with me thinking if the dog came that close again I'd spray it. Well, it did and I sprayed... and nothing. I don't see how I could have missed. The dog was less than three feet away and I sprayed 2-3 times. Finally I got so far away from its yard, the dog stopped chasing me, but no thanks to the pepper spray.
I tested the spray when I got home. It does work. It's not past expiration date. It's a well-reviewed brand. It just had no effect on this dog.
Has anyone else had any success with sprays to discourage dogs from chasing you? If so, what did you use?
