O teste de Volhard é uma maneira interessante de se analisar o temperamento de um filhote, contribuindo assim por uma boa escolha pelo criador ou tutor.

Além de ser útil para selecionar o filhote mais adequado para cada família, o teste é ideal para se fazer em ninhadas para a seleção de cães guia.
