my roommate said the same thing about training my puppy (she's toooo young!) my puppy as of today (happy birthday!) is 9 weeks old and already knows how to SIT and lay DOWN. it's the cutest thing because she's so small.
this just goes to prove that yorkies are the SMARTEST DOGS in the WORLD!
well, except for house breaking.
a tip i learned from a book: don't repeat, use the 10 second rule. puppies take a while to process commands, so count to 10 slowly before repeating yourself! i bet you a cookie that in that time span they'll obey your command!
