I now what you mean Dawn. EVERYONE (even on here) says OMG Bella is soooo tiny!!! Im like no, not really she is 4.6 -4.11 pounds she changes every visit lol. She is solid. Not fragile and vet said her frame could stand to be a 3-4 pounder (she is petite) her hair is long so you cannot tell but when u pick her up she is a rock. Now my other id Diggy he is barely over 3 pounds at 5.5 months and he is like hollow. Just nothing to him and seems more fragile than Bella. I think they are like us all carry weight differently and hard to tell with longer coats. Some look so small to us yet only a pound heavier YES a pound seems to make a huge difference!
