I love dogs! I have a yorkie named Obi.
That is awesome, I have never owned a dog but they have been humans companions for a while giving them the name mans best friend. 
That is true, do you own any dogs?
No i do not but I would love to get a German Sheppard or Doberman 
German Sheppards are great with kids I hear
Yes i heard that also but if I had to pick it would be Doberman with its distinct markings on its chest and above the eyes.
They are great dogs. I think everyone should have a dog atleast once in their life.
I completely agree and it is just amazing how they have acquired the ability to understand and communicate with humans.
