Welcome to the forum! I myself am new to this forum & also new to owning a GSD. I have a almost 10 month old female, and have found many helpful things on here.
From my short experience though and in response to your question, I started our pup at puppy preschool around 12 weeks. Waited till she had all immunisations,
. We stopped shortly after as we didn't like the school we attended then did basic training at home. Started up obedience classes at 6 months which lasted for about 6 weeks until I was too busy at work... Plus I found she got bored doing the basics we had learnt at home. Am going to kick start classes again at around 12 months..
Also only fed her biscuit diet as recommended from her breeder, she has royal canin... Where bouts in Australia do you live? We're up in Qld!
