Ok, my son is now the same age as Caylee was when this supposed conversation about the dog took place. I conducted a little sleuth experiment with my own darling boy. He has an average vocabulary for a child his age, not advanced or behind the curve.
I asked him " what do you know about dogs?" and he answered " where's the cute?" which is what he refers to 2 of our dogs as. ( we have a chihuahua, and a rottweiler puppy, and a red heeler or austrailian cattle dog. ) I asked him "whose dog is that, and pointed to the chihuahua", he responded " the cute" I asked him what color are the dogs?" He responded " woof". I asked him " what's this dogs name, and pointed to the rottweiler, he responded " oh so cute".
I hope this little experiement helps those of you without toddlers to understand what kinds of conversations they are capable of at this age. Every child is different, but I do not think any child at at that age could tell you she played with a white pomeranian that belonged to Zanny today.
