Default Warning to dogs and people that swim in lakes and ponds

this is mostly hysteria. the report is a single incident, endlessly
reposted like a virus. of all the hunting dogs jumping into endless
bodies of water to retrieve countless numbers of birds and chomping
drinking the water, I have never heard of this before.

dont take a dog swimming in a stinking pond with a thick foul smelling
scum of algae on top.

"Summary: The growth of highly toxic blue-green algae can occur in the
waters of Indiana. Poisoning by the neurotoxins causes rapid death
with or without signs of cholinesterase inhibition. Poisoning by the
hepatotoxins causes massive liver necrosis with severe intrahepatic
hemorrhage and death. Diagnosis is based on history of exposure,
clinical signs,blue-green algae in the GI tract, and necropsy
findings.

Introduction: Blue-green algae are not true algae, but are
cyanobacteria which grow in fresh water in temperate areas world-wide,
including Indiana.
Under the appropriate weather and water conditions, usually in the
late summer or fall after a drought, the blue-green algae can form a
rapidly growing "bloom". These blooms can occur in farm ponds and
larger bodies of water forming a thick, often foul-smelling scum of
brown, to green, to blue-green algae. Winds can then blow the
blue-green algae to the shore and concentrate it where the animals
have to drink it with the water. In many instances, the algae will not
be poisonous. However, sometimes, for unknown reasons, the blue-green
algae in these blooms form ncuroloxinsor hepatotoxins which can prove
deadly to animals drinking the water."http://www.addl.purdue.edu/newsletters/1996/fall/bluegreenalgae.shtml

That's creepy. my dog used to swim like every day, and the water was
covered in green algae all summer, as most of the stagnant water near
the shores of lakes and ponds always is. made him stink, for sure.
