YES, i guess it's just like for us. people (dr's) can guess our height as children and can show us what we SHOULD weigh, at any stage in our lives, for our height, but that does NOT always become our reality does it? lol.
there are estimates, approximates, but every dog i'm sure, like us, have different metabolisms, and appetites to. i wouldn't buy a lifetime of clothing banking on it..maybe just a couple hundred dollars *blush*, lol. so far i've guessed pretty darn good
i would not complain if she was beefier!
