Yeah, right... The cyclists who get chased and bitten sure do. Interestingly, I've NEVER had a problem with a dog in the city (despite encountering many dogs - I seek them out, 'cause I absolutely love them) and have been chased by a dog in the country more than once (and I know enough of dog body language to tell that at least some of them weren't chasing "just to play"...) From what I've seen, I conclude that country dogs are poorer socialized and more aggressive and territorial than the city dogs. It makes sense, given the different environments.
