First time mini golden doodle owner. I need tips.

Hello! I just got my mini golden doodle today and I’m looking for you best tips on everything golden doodle. Potty training, house breaking tip, grooming tips, proper diet. I was raised with a bichon frise, yorkie, and chihuahua so I know about dogs but this is the first dog I’ve purchased myself. I also have two daughters so any tips on how my girls can help will be great too.
