Why do dogs shiver when they're nervous or excited?

NO, they don't all do it. Nervy dogs born this way do it, dogs with shitty temperaments who "leak" drive do it, sound dogs do NOT and I would put down any animal I owned who was this weak nerved, end of story.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
