Lost her tooth! =0

At 4.5 months, Bella(our Bichon puppy) has lost her first baby tooth. Her right front tooth is gone. Not sure where the tooth went. The vet said that dogs usually swallow them and no one would know...

As you can see, even her lower front teeth are becoming loose (and, as a result, look crooked in this photo).

She's a smartone. She responds when you call her name. She knows "sit", "down", "hand" and "up".

We've been toilet-training her, and she gets it right 95% of the time. We used to give her treats whenever she "went" in the right spot.

And now, after going pee in the right spot on the wee wee pads, she will approachyou, wagher tail and nudge her head in the direction of the wee wee pad, as if to tell us to look there, in hopes of getting a treat.  We didn't teach her that!!!

More photos of her with her "IQ toy", a toy where treats can be dispensed if she rolls it at a certain angle/ position.
