英文は一つの文章が長い場合、意味を取りづらくなります。今回の課題文が長くなっている理由は関係詞節が３つあるためです（２つ目の関係詞節は１つ目の中に含まれています）。こうした場合、関係詞節をカッコでくくると、文章の骨格（中心部分）がはっきりします。
One day Dandy（, who after the manner of his kind, had attached himself to the person who was always willing to take him out for a stroll,）followed his friend to a neighbouring public-house,（where the said friend had to discuss some business matter with the landlord）.→ カッコ内の語句を省きます→ One day Dandy followed his friend to a neighbouring public-house.→ 文章の骨格がはっきりしました。
文章の骨格の意味をとったうえで、関係詞節の意味を加えると全体の意味をつかむのが楽になります。
