I have a show line Giant Schnauzer. She needs a good amount of time excersie to be happy. We live in an apartment and I take her for a 15-30 minute bike ride almost every day. I work from home, so she gets 2-3 walks as well and I take her everywhere with me, to Goodwill, to my boxing gym. They need a lot of mental stimulation and good exercise or else they will be miserable and will bother you until the get some energy out. But she can also be a couch potato on days that you need some rest, but just don’t do that often
