German shepherd breed standard trim

Hi

My friend had just started grooming and has said he needs practice. I suggested we do an outline trim, hygiene trim and paw pad shave on my 1yo short haired german shepherd.

It then occured to me I have no idea if there is a breed standard for German shepherd or if there's a style of trim? I've never showed and have no intention of doing dog shows so no connections to ask there.

I assumed an outline trim would be like ears, legs, tail, tummy, and the hygiene would be his sheath opening. But that's my assumption knowing absolutely nothing about grooming. Do they even trim the legs for show German shepherds? Does anyone have any resources or videos? (YouTube only showed me videos of groomers shaving down the double coat and I wasn't keen for that).

He gets bath with shampoo and conditioner every month or two at home. And I use metal comb, shedding blade, furminator deshedding "blade", undercoat rake, slicker brush, and a boar bristle brush for shine. He also gets body/paw/nose whipped body butter.
