Update.
After the watergardening labradors returned
from their near encounter with the rattlesnakes
they waded in and out of the little bog twice.
Frog eggs may, or may not, have survived
that. The area is big enough for two labradors
to stand side by side but not much else.
Oh well... when it is all said and done I love
my dogs more than the frogs and after thinking
what we might have been dealing with yesterday,
two snake bit dogs, on Easter... I'll take two safe
dogs anyday.
