It's funny when the pups come out for the first time to dog club (they are usually quite young). They usually try and back out or chew on their leads or just stop altogether and refuse to go anywhere. I think it's something they get used to pretty quickly. Teaching to walk quietly without pulling or plowing through the bushes like a wombat can be harder.
Shepherds are great. I love our three. They are big trouble sometimes though! I remember one time our older two rode the baby gate (divides the kitchen from the lounge and dining) all the way to the ground one night after jumping on it to bark at the cats. Other times you will go down and there will be tea towels on the ground, chairs knocked over, the back door open, mud everywhere and our two females wrestling on their beds. My boy Ares was up on the bench this morning very silently and sneakily licking the brand new sour cream I'd just opened.
My mum has been slacking off on obedience because we show our two females but I am making her take our 8 month old again once she comes off heat as they get too out of control if you don't keep it up.
