The mark consists of a stylized illustration of a white dog dressed in a green detective coat, red bow tie, and red fedora hat with a dark purple band. The dog is holding a magnifying glass in its paw, raised to its eye, giving the impression of inspecting or investigating. The illustration is framed within a rounded arch shape with a golden yellow background and a thick dark purple border. Below the illustration, the text "MOLD DOG PRO" appears in bold, uppercase green letters with a white and golden yellow outline that creates a three-dimensional effect. Underneath, the tagline "CANINE MOLD DETECTION" is written in smaller, uppercase dark purple letters with a similar white and golden yellow outline, giving a shadowed look.
