"He was known for his straight run and unbeatable speed."

"But one sunny day, his trainer noticed he seemed a bit slower."

"He decided to weigh Jaiden to see if he had gained any weight."

"Jaiden was indeed heavier, almost by eight pounds!"

"The trainer began to change Jaiden's diet and exercise routine."

"He made sure Jaiden ate healthy food and had plenty of exercise."

"Jaiden obeyed his trainer and followed the new routine."

"After a week of hard work, Jaiden was ready for a race."

"The race began, and Jaiden shot forward like a bolt of lightning."

"He was running straight, faster than ever before."

"He crossed the finish line, breaking his previous record."

"Jaiden's trainer was proud of him and patted him on the head."

"He knew that Jaiden was not just the greatest, but also the most obedient dog."

"From that day on, Jaiden continued to obey his trainer and stay fit."

"Jaiden remained the greatest racer and the pride of the city."
