Excellent advice. I was told to give my GSD pup short walks when young and build up gradually until about a year old to avoid joint damage. Like B42T I also had to replace my car to accommodate him, and bought a van so he had plenty of room and it didn't matter how filthy he wasI'm sure you've been given all the advice under the sun but just be very carefull about over exercise and boisterous stuff whill she is still growing. More so with big leggy dogs any injuries or excessive strain on joints and that long back can lead to a lot of problems in later life. I recall years a go a mate had a Dane similar age to yours a big gangly long legged youth, they were out in the fields he was running full bore, turned slipped and the result was disasterous, poor lad never even got back home.
