Haha my dog used to be like kinda like that, she would just sit there and STARE at me for like.. 10 minutes. Then she would start barking really loudly.
my little wiener dog will come running into a room that I am in look at me and i'll say hi to her and then she'll leave again. She just wants reassurance that her mommy didn't leave her. Zoey is her name...such a cutie!!!
