If frequent cleaning does not control pet odor, consider deeper interventions. First, ensure your pet is healthy, as odors can stem from untreated medical issues. Regular baths and grooming can reduce odors from the pet itself. For home odors, use enzymatic cleaners designed to break down pet odors at the molecular level, particularly on carpets and furniture. Air purifiers can also help by removing pet dander and odor particles from the air. If these steps are insufficient, consulting a veterinarian to rule out health issues is advised.
