My 94 year old grandmom with her body guard dog "Dickroose". It's a daily routine for my grand mom to go for a quick walk in the lawn to maintain herself. This is her practice for decades now. It is difficult for us to draw the boundary of the walking lawn. It is Dickroose duty to determine the distance my grandmom can walk based on the climate and her health condition. If grand mom is crossing the limit then Dickroose wil pull her back.
