Can black pepper kill fleas on dogs?

Black pepper is not an effective or safe method for killing fleas on dogs. While it may have some insect-repelling properties, it can also irritate a dog's skin and respiratory system. For effective flea control, it's best to use veterinarian-recommended treatments, such as topical solutions, oral medications, or flea collars. Always consult with a veterinarian for safe and effective flea management options.
