Well as a student who works and who raised a puppy I would say go with w/e age makes you the most comfortable, maybe it was more work but I wouldn't trade her for any other dog ever! Honestly I didn't find it to be that much work because lets face it puppies are cute, and theres a reason for that

You can't stay mad or frustrated at them for long
As far as GSD vs Husky, our friend has a husky she adopted when he was 1.5 and he has absolutely no interest in her cat. So like any dog it depends on the personality. I personaly LOVE the way huskys look but same with the GSDs and for me having been around both I would choose the GSD for personality and looks any day, but its a personal preferance, ask my friend and she would probably choose the husky
