Can You Get Chiggers from Your Dog?

Chiggers, known scientifically as trombiculid mite larvae, are parasitic mites that commonly inhabit grassy and wooded areas, particularly during warm, humid conditions in late spring through early fall. They go by many names, including harvest mites, red bugs, berry bugs, bush mites, and itch mites. Found globally, these mites pose a seasonal nuisance to pets and humans who frequent natural outdoor environments. Understanding how chiggers interact with dogs and whether they pose a risk to humans is essential for keeping both people and pets safe.

What Are Chiggers?

Chiggers are not insects but larval mites that are too small to see with the naked eye. They do not pierce the skin to feed on blood or burrow into the body. Instead, they use their specialized hooked mouthparts to inject digestive enzymes that liquefy skin cells, which they then consume through a feeding tube called a stylostome. Once feeding is complete over several days, the larvae detach and drop off the host.

Sources of Chigger Exposure

• Chiggers live in grasses, weeds, and dense brush.
• They are most active during late spring through early fall.
• Dogs pick them up while walking or playing in infested outdoor areas.
• Chiggers are not transmitted from pets to humans directly.

Importantly, while dogs may carry chiggers after playing outside, humans cannot get chiggers from their dogs. Transmission occurs when a person enters a chigger-infested environment, not through contact with a chigger-carrying pet.

Symptoms of Chigger Infestation in Dogs

Dogs suffering from chigger bites may display:

• Intense itching and scratching
• Red raised bumps or rashes
• Localized hair loss
• Secondary skin infections from repeated scratching
• In severe cases, systemic symptoms like fever or confusion

Chiggers prefer areas with less fur and thinner skin, including the belly, ears, face, and between paw pads. Dogs may bite, lick, or scratch these areas excessively.

Diagnosing Chigger Infestations in Pets

Veterinarians diagnose chigger infestations through:

• Physical examination to detect red bumps, rashes, and other symptoms
• Skin scrapings viewed under a microscope
• Identification of orange-red mites or crusts on the skin

Due to their small size, chiggers can be difficult to detect without proper veterinary tools and expertise.

Treating Chigger Infestations in Dogs

Managing a chigger infestation involves multiple steps:

1. Bathe the dog in warm, soapy water to remove mites.
2. Wipe affected areas with a soft cloth.
3. Apply topical or oral antiparasitic medications such as fipronil or permethrin.
4. Use preventive products like Frontline or Seresto collars.
5. Administer anti-inflammatory medications if needed.
6. Treat secondary infections with antibiotics if present.
7. Provide supportive care: oatmeal baths, hydrocortisone, aloe vera, or calamine lotion (with veterinary approval).
8. Prevent self-trauma using cones or topical barriers.
9. Clean bedding and environment: wash fabrics in hot water and maintain low grass.
10. Use approved yard sprays (e.g., permethrin-based), ensuring pets stay away until areas are dry.

Chigger infestations usually resolve within a week. These mites do not live long-term on pets and cannot reproduce indoors, making indoor infestations extremely unlikely.

Preventing Chigger Infestations

• Avoid tall grasses and heavy brush during walks.
• Keep pets on a leashed path in unknown environments.
• Use monthly parasite preventives recommended by a vet.
• Regularly examine and groom pets especially after time outdoors.
• Maintain yards by mowing and removing weeds or dense vegetation.

By limiting outdoor exposure and maintaining personal and environmental hygiene, the risks posed by chigger infestations in pets and potential secondary infections can be greatly reduced.

Chiggers and Human Safety

While chiggers can and do attach to humans, the source of infestation is the environment, not pets. Humans exposed to the same habitat as a dog may also get bitten, but direct transmission from dog to human does not occur. These mites do not jump or fly, and they do not move between hosts.

Conclusion

If your dog shows signs of intense itching or red bumps after visiting grassy or wooded areas during peak chigger season, consult your veterinarian. Early diagnosis and treatment can prevent complications such as secondary infections and systemic issues. With appropriate precautions and treatment, both you and your pet can safely enjoy the outdoors during chigger season.
