Yes, they do seem to come in fast! Mia's have been coming & going for the last few months. A few weeks ago we took Mia to the vet's office but her regular Dr was off so we saw a new guy, he tried to tell us that ALL of her baby teeth should have been out by now... I laughed and told him I had just found one a couple of days prior (and she was almost 7 months). We had her spayed last Thurs - they pulled the 4 tall ones (canine?) and 1 baby that was already coming out... but guess what I found yesterday? Yep, another tooth (molar).
