Tottori Kenichi is a foul-mouthed but gifted veterinarian nicknamed Dolittle. His catch phrase is ‘pet care means business’. He is the director of his animal clinic and rescues not only ‘voiceless’ pets but also helps their owners, who lack understanding and caution, 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.
