Lassie is main protagonist of Lassie.
Lassie was born and raised in a petstore. He liked it there and everytime he was adopted, he ran back to it. In the end, no one wanted him because he was no longer a cute, little puppy.
He meets the girl, Akutsu in the store and becomes very fond of her. Akutsu takes him for walks, plays with him and feeds him. However, Lassie is sold to another family before Akutsu could afford to buy him. Now Lassie begins his journey back to find Akutsu. On his way, he meets the German Shepherd, German. First he saves him, but later Lassie returns the favor. He helps German learn to trust humans again and helps him find a new home with the boy, Shingo.
Afterwards, he continues his journey and meets a Shiba called, Chiyomaru. He too helps him get back and reunited with his owner. After this long journey, he's taken care of by Chiyomaru's owner, Seinosuke Ando. Seinosuke calls the petstore to find out if they are missing a Collie. It turns out that it's the same store Lassie originally came from and where Akutsu works. He's then finally reunited with Akutsu to live happily ever after.
