I think it can be entertaining for anyone. Some people live their entire lives based off of things like this (palm readings, tarot cards, etc), but I just think reading up on your sign is interesting when it does match a lot of your personality traits. And in that, moving it to the dog population is silly in some aspects, however, when my vet tells me to read my dog a book to calm her in the bath, I might choose Ghandi because that was recommended for a Libra dog
