We got Tucker when he was 8 weeks, at 10 weeks he was 2.5 pounds, but he gained another 2.5 pounds in 6 weeks. Ive read that some reach thier weight faster than others and some slowly gain untill they are 15 months or so, but the generally consus is that both poodles and yorkies usually stop growing at 6 months.
Sounds like she is doing great with her training!! Tuck goes to bed between 9 and 10pm and usually sleeps untill 5 or 6 am then he is a little spit fire and runs around for hours!!
