It's so neat how quickly they grow! It seems that every day they're a little longer, taller, wider! Your baby probably has topped off at 7 - but ya never know!!
It's also funny that we all view a dog over 7 lbs as somehow being big. In the scheme of things, it's still very tiny.
I weigh Lucy every week to see the ounces adding up. She'll probably hit 7 too.
Enjoy you baby!
