You were not sure. You called the vet. It was nothing. Plant a tree for the call you almost did not make.
Write your own moment on the tree message, and close it the way every tree here closes: Not me. A vet. Now.
Started by someone who works with horses and dogs in Germany. He is not a vet. He plants a tree every time he sends someone past himself and straight to a vet.
It grew out of a free public list of warning signs. The list never names an illness. It names who should look.
Plant one when it turned out to be nothing. Nothing is a good answer.
