Thanks for the encouraging post. You must be so pleased with the progress your girl has made
I have been doing the Good Citizens with both of mine, my 20 month old boy is in the gold class, and my 6 month old girl is doing her bronze test on Saturday

. Both of mine have had consistant training from being with us at 8 weeks old and have attended training classes weekly from the time they had all of their jabs, and I agree it doesn't happen over night, it does take time and bloody hard work, and you do have days where you pull your hair out and wonder why the hell you bother

but it really does pay off. I also do think that maturity does play a part. My boy was a complete handfull as a pup, but since about the age of 15 months old its as though he has really grown up and lost the puppy excitement which makes him more more responsive in training
