"Do you remember when we went to pick up Hally from her litter (a group of baby dogs)? We picked her because she looked like her mom. She was brown with spots, with long ears, and she was energetic, so we thought she'd be strong, like her mom. But how does she look now?" Mom asked.
"Well," though Sam. "She's still brown with spots and long ears, but she's not very energetic or strong anymore."
"That's what the vet said, too. We didn't let her exercise as much, and we often fed her a lot. She will probably look just like her mom now if we let her exercise as much as her mom. We have to start walking her more often so that she'll stay healthy for a long time. Will you help?"
"Sure!" said Sam. He decided that he could play fetch with her every day in the yard, because then she could run and run and run until she was tired. The first day, they only played fetch for about 10 minutes before Hally was tired. But Sam kept playing with her every day. Soon, they could play for half an hour! Hally looked stronger every day, just like her mom. Sam felt great about helping Hally get strong again.
