Can Garlic Keep Fleas Off Dogs?

Fleas are an endless source of frustration for dogs and dog owners. People who have tried powders, shampoos and collars to little or no avail look to natural sources as an alternative. One such popular source is garlic.

  1. Theories/Speculation

    • Many dog owners believe garlic is the best solution for fleas. Tests have shown garlic-saturated skin and hair might repel fleas more effectively than nongarlic-saturated skin and hair. But scientists aren't sure if garlic repels fleas or only reduces allergic reactions to fleas.

    Fun Fact

    • Texts dating to the Middle Ages suggest sleeping with garlic cloves between your toes will repulse invading fleas and other bloodsucking bed bugs. This might have inspired the equally venerable tradition that garlic is offensive to vampires.

    Considerations

    • The scientific and testimonial evidence is enough to legitimize garlic as at least an option to get rid of fleas.

    Expert Insight

    • Veterinarians and other animal experts differ over garlic's value as a flea deterrent. Garlic's medicinal value might depend on the individual taking the garlic. Talk to your veterinarian about garlic's potential for your dog specifically.

    Warning

    • Garlic has a toxic effect on small animals, including toy and miniature dog breeds. It attacks their red blood cells and causes anemia. Indiscriminately consumed, garlic is unhealthy for dogs of all sizes. Large dogs should receive garlic only in moderate doses.
