We were at the vet today. So...
Yoshi: 12 wks = 2.3 lbs / now, 1 year = 7.2 lbs
Momo: 12 wks = 4.2 lbs / now, 9 mos = 8.6 lbs
Both are healthy & happy
Interesting to see in this thread how impossible it really is to predict adult weight. Yoshi was the same size at 12 wks as other Yorkies who are now in between 3-12 lbs as an adult. That's a huge window.
When I had Momo's DNA tested, the report came back telling me that she would weigh in between 5-10 lbs. Even a DNA test can't give a good prediction! Lol
