I talk to Fido a little bit, I use ''baby voice'' much cause then he wags his tail so much and its soo cute
I mostly just talk to him when I'm asking him for something like: Do you wanna go for a walk? are you hungry ? want a treat?
Also often when I'm in the computer (its a small laptop that I often have on my bed) he puts his head on the screen so it falls down and the computer turns off, I can't ban him that cause he does his puppylook then ! its soooo cute, then I talk to him and ask him : Fido what where you doing ? you are not suppose to do that, but damn your so cute !!! and then I hug him to death almost haha
