yes, it is very different. When I was showing my zois they would do 5 miles a day at a steady trot and then have free running, encouraged to run up very steep hills as fast as they could. Pretty much every judge I went under commented on their condition and excellent muscle tone. My current dog who isn't shown walks for about 3 hours a day, running if he likes, mostly just mooching around and his muscles aren't anything like what I want in a show dog.
As she's such a big breed I would start just gradually increasing her on lead walks. Just walking at a brisk pace, no stopping to sniff or chat.
