My old pitty learned words like the dog in that second article! He knew the names of all of our roomates (Austin, Brandon, Cory and Chelsie), he knew my dad as Papa (and he knew "Papa's house", the names of all his toys (ball, bunny, teddy, bone, and ropetoy) He knew the difference between a beer and a soda, and would get you whichever one you asked for! He knew "friend" very well, as he was quite protective over me, when he met new ppl he would watch them untill i told him that person is a friend... he was incredibly smart! He responded to "Ki, go play in your room." or "Ki, come watch Dog Whisperer!"
Brilliant little pup.
