Very sad, but I found your reporting tastefully done Morris.
We've had things like rabies outbreaks here in central FL that hit everything from stray cats to racoons etc, parvo and canine distemper, red tide, mosquito born illnesses, now outbreaks of avian flu to worry about and a host of others that effect cow's, never mind urban sprawl, etc. Who knows the long term effect of the sewage leak into the Potomac? I know one of the ways the feds tracked Covid outbreaks was testing the water at the local sewage treatment plants for concentrations of virus in the pre-treated water... It's almost like the plagues of Egypt out there for the animals... sometimes it is easy to forget it's not just humans dealing with this stuff.
A lot of old common sense stuff people used to do for prevention has been lost to the younger generation... like not leaving anything outside that could hold water facing upward where mosquitos could breed, isolating your animals more effectively, there were no such things as fenced off dog parks where things are more concentrated. City dumps with biological waste, that birds feed on. Some preventative stuff was relegated to old wives tales, but some stuff worked and has been lost to history. Seems almost like we have to re-learn old lessons over and over and learn some new one's too.
