I love dogs. They truly live up to their nickname "man's best friend."
Dogs are great! And a woman's best friend.
It's probably because they are the first species to have been domesticated and selectively bred for various behaviors and traits.
Oh, very interesting. That sounds accurate.
I think this is what allows them to appeal to so many different kinds of people. They can hunt, herd, protect, be a friend, and even help the handicapped! 
So true! Dogs really are great for stress too.
It's crazy to think that they are sister taxa with the extant grey wolf, making them distantly related to modern wolves.
That is very crazy. To think that we are playing with wolves!
