Description
Miyu Samura is the protagonist of the anime Dog Signal. He is an adult man with short blonde hair and yellow eyes. At the beginning of the story, he is described as an indecisive young man whose life takes a turn when his ex-girlfriend breaks up with him and leaves him with a dog he does not know how to care for. While walking that dog, he encounters Shinichiro Niwa, a highly skilled dog trainer, and this chance meeting becomes a turning point.

Miyu's initial personality is marked by uncertainty and a lack of direction. His motivation at first is simply trying to manage the situation he has been put in, but as he learns from Niwa and others, he develops a genuine interest in understanding dogs and becoming a responsible owner. His overarching motivation grows into a desire to become a dog trainer himself, aiming to help bridge the gap between people and their canine companions.

In the story, Miyu serves as the main viewpoint character through whom the audience learns about dog care, training, and the importance of the human-animal bond. His role is that of a learner and protagonist whose personal growth mirrors the educational themes of the series.

Key relationships include his mentor and friend Shinichiro Niwa, who guides him through the fundamentals of dog training and offers support during difficult moments. He also interacts with the veteran trainer Ritsuka Izumi and the veterinarian Suzunosuke Kubo, both of whom contribute to his education and development. His family, particularly his mother and sister, appear in his background as part of his support network.

Throughout the series, Miyu undergoes significant development. He moves from indecisiveness and passivity to a more confident, proactive mindset. He learns to take responsibility not only for the dog under his care but for his own choices. His notable abilities are not physical or combative but revolve around his growing expertise in dog behavior, training techniques, and his empathetic approach to both animals and their owners. By the end of the series, he has transformed into a competent and compassionate individual who actively works to improve the lives of dogs and the people who love them.
