I honestly didn't read down to CS1's post before posting my 2 cents...

I have to agree with Stacey here, to just blindly state the animal is infected and call authorities to remove it, and most likely put it down would be a shame. That is just as bad racial profiling with capital punishment as the outcome. The Fox didn't show aggressive behavior... I've been chased in the exact same manner as described by neighborhood dogs countless times, it isn't too far fetched to assume a fox would behave in the same manner at 7 in the morning along a bike trail through his territory.
