Chuck and Duke shared understanding and responsibility for each other Chuck made the effect and finally walked because of duke. Duke remained at his side during his most difficult time.

Detailed Answer:

Duke was a loyal, faithful, understanding and intelligent dog. He had realized Chuck’s handicap after their very first meeting. Since then he did not ever jump at him after that. Duke would keep on motivating Chuck to move by nudging and poking him. He took Chuck for walk every day, covering a greater distance than before every time. Later, he insisted on two rounds in a day. Largely due to Duke’s efforts Chuck recovered. Yet, when the time came to reap the fruits of one’s efforts, to see Chuck being promoted in the office, he died. But such kind acts are always remembered by the one who are benefitted by his efforts. They are regarded as motivators and God’s messengers.
