My girl weighed in at 6.3 lbs at the vet's (baby scale) back in February at a year old. She's currently at the same weight on my food scale. Measuring from base of neck to rump and then from rump to floor, she comes in at 11" x 11". A skinny girl but a fair sized rib area.
The following pictures are all current within the past month (March/April). Her hair's growing in a bit so it hides her skinny legs well, but here's her length relative to a Wii Fit balance board in Picture #1. Her size relative to a Hide-A-Squirrel Jr. in Picture #2. Finally, in Picture #3, she's showing off her body at full stretch.
