I am looking for a series of 20 interesting facts about dogs.  I want
facts that aren't commonly known as well as facts that are
interesting/amusing to read.

Most of the facts should pertain in some way to dog training.  Please
write them in your own words--don't copy and paste from websites or
just provide links.

Have you read the Terms of Service for Google Answers?

Yes I have read the TOS, I don't see how that applies to my question.  

Thanks

Since your other dog-related question asked for original material that
could be used without copyright restrictions, I believe Bobbie7 just
wanted to remind you that material posted on Google Answers belongs to
Google. If a Google Answers Researcher creates something in his or her
own words, Google will hold the copyright on that material. Sometimes
customers are not aware of this.

I appreciate that.  But, yes I am aware of the copyright issues
regarding the use of google answers.  Thanks for reminding me.

Have you read "Marley and Me" by John Grogan?
