Tottori Kenichi is a foul-mouthed but gifted veterinarian nicknamed Dolittle. His catch phrase is 'pet care means business'. He is the director of a animal clinic and rescues not only 'voiceless' pets, but also helps their owners with their problems and worries. Working with him is animal nurse Tajima Asuka. Hanabishi Masaru is Dolittle's rival, a charismatic vet and director of another animal hospital who has not only an opposite personality but also a different stance towards pet care. The drama focuses on the love triangle between these three characters and tries to teach the viewers about human-pet relationships.
