they want you to
throw up.
yes.
the next time your little
puppy comes up to you and starts making happy
with its
tongue, keep in mind that
in the wild, this
behavior was a
signal for the
mother dog (or whoever hunted within the group) to
regurgitate whatever
food it happened to find that day so that all could
share. rather efficient means of transport,
neh?
your dog is not trying to make
friends. it's probably just hungry.
