i've seen this before. i only have one yorkie but the yorkie i used to go visit all the time before I got my own
she was soooooooooo tiny. i could have sworn she was a good 3 lbs at the MOST. i took maggie to visit and they were almost the same size...so I said "Dazzle weighs what...3 lbs??" they said "no, 7" I about died. maggie was 3 lbs and looked about the same size. i figured dazzle could have been a tad more than maggie since she is full grown but not 4 lbs more!!!i never would have guessed. i guess it is all in build of the dog..muscle, etc. just like people.
