There are many people who argue that a dog is man's best friend:

"Animals are such agreeable friends. They ask no questions, they pass no criticisms." ― George Elliot

 "No one appreciates the very special genius of your conversation as the dog does." ― Christopher Morley

 "A dog is the only thing on earth that loves you more than he loves himself." ― Josh Billings

But I present to you the truest, the bestest, the most faithful, the most loyal, the most beautiful creature of all.

Yes.

It is the rare creature Potadog. 

If you find one, cherish it. For they, indeed are the most wonderful creatures to bless the surface of this poor earth.
