Animals communicate in a nonverbal language of the senses and emotions:
pictures, sounds, smells, feelings, etc.  It is a universal language shared by all
species all over the world because pictures and feelings are the same in any
language.  Like humans, animals also use body language.  It adds emphasis to
their telepathic language.

Our animals are reading our minds all the time.  They see our thoughts; they
know what we're thinking.  If you have ever considered giving your bath-hating
dog a bath and he immediately ran to hide, you have seen this communication
at work.  A pretty afternoon that brings the thought of a walk in the park may
result in your dog waiting anxiously by the door or pestering you to get the
leash.  They saw your thoughts and believed you were going for a walk.

Children are born with the ability to use this form of communication.  They can,
and often do, converse with the pets in their family.  However, when children
start to verbalize and learn to read, they forget their first language (the
language the animals still use).  It can be re-learned.

Anyone who uses this form of communication can talk with the animals.  The
most difficult part is learning to ignore one's logic.  Because we know our own
pets so well, they are often the most difficult for us to get information from.  
Fortunately, sending information to our own pets is easy.
