I received this email and thought it so true..I thought this would be a good place to post it...

A dog's purpose, from a 4-year-old's perspective,
as related by a veterinarian:

Being a veterinarian, I had been called to examine
a ten-year-old Irish wolfhound named Belker. The
dog's owners, Ron, his wife, Lisa, and their
little boy, Shane, were all very attached to
Belker, and they were hoping for a miracle.
I examined Belker and found he was dying of
cancer. I told the family we couldn't do anything
for Belker, and offered to perform the euthanasia
procedure for the old dog in their home.
As we made arrangements, Ron and Lisa told me
they thought it would be good for four-year-old
Shane to observe the procedure. They felt as
though Shane might learn something from the
experience.
The next day, I felt the familiar catch in my
throat as Belker's family surrounded him. Shane
seemed so calm, petting the old dog for the last
time, that I wondered if he understood what was
going on.
Within a few minutes, Belker slipped
peacefully away. The little boy seemed to accept
Belker's transition without any difficulty or
confusion.
We sat together for a while after Belker's
death, wondering aloud about the sad fact that
animal lives are shorter than human lives. Shane,
who had been listening quietly, piped up, 'I know
why.'
Startled, we all turned to him. What came out
of his mouth next stunned me. I'd never heard a
more comforting explanation. He said, "People are
born so that they can learn how to live a good
life -- like loving everybody all the time and
being nice, right?" The four-year-old continued,
"Well, dogs already know how to do that, so they
don't have to stay as long."

that is priceless. makes sense even.
