Once there was a pup named Charlie. Today was a special day: his first day at Puppy School.

Charlie had floppy ears and a tail that wouldn't stop wagging. He carried a little red backpack.

He said goodbye to his mom and promised to be brave. The school building was big and full of sounds.

Inside, there were pups of all colors and breeds. Charlie felt shy and clutched his backpack tighter.

Mrs. Woofington, a kind bulldog, was their teacher. She gave them each a treat and a smile.

Charlie sat next to Spike, a small, energetic terrier, who talked about all the bones he had buried.

They went to play fetch, and Charlie ran faster than he ever had, his ears flying in the wind.

During nap time, Charlie felt homesick. He missed his mom and his warm, cozy bed.

Spike noticed and patted Charlie's back with his paw, telling him he'd be okay and they could play later.

When lunchtime came, Charlie opened his backpack to find extra treats his mom packed for new friends.

Happily, he shared his treats with Spike and the other puppies, and they wagged their tails in delight.

By the end of the day, Charlie made many friends. He couldn't wait to tell his mom all about it.
