Wait, your Vet told you to read a book to your dog to calm it? Really? Am I misunderstanding?
It's kind of a fun thing (for humans or for dogs) - I would not live my life by it, nor design my dog's life around it. Heck, I had a Libra dog (Madeleine), and if you look at the traits astronomy affixes to this sign, there was a lot of truth to it, LOL.
