Fleas and Ticks in Dogs: A Treatment and Prevention Guide

Flea and tick infestations are a common health problem that can have serious consequences. These parasites are responsible for transmitting numerous infectious diseases (Lyme disease, ehrlichiosis, babesiosis) and also pose a danger to humans.


1. Identify Flea and Tick Infestations

Early detection is crucial. Regularly inspect your dog's coat and skin.

Chips

  • Signs: Excessive itching, irritated skin.
  • Detection: The presence of flea droppings (small black specks) is a key indicator. When moistened, these droppings leave a reddish tint due to their high content of digested blood (Dryden et al., 2009).

Ticks

  • Areas to inspect: Warm and protected areas such as the ears, armpits or interdigital spaces.
  • Risk: Ticks attach themselves to feed on blood. They can transmit pathogens in just 24 to 48 hours . Ixodes ticks are the primary vectors of Lyme disease.

2. Treat Your Dog Against Fleas and Ticks

Immediate curative treatment is essential to eliminate the parasites.

Flea Treatment

  • Flea baths : Effective at killing adult fleas. Shampoos containing fipronil or permethrin offer significant reduction in a single application.
  • Topical treatments (pipettes): These work by interrupting the flea life cycle (adults, eggs, and larvae). They offer long-lasting protection (4 to 8 weeks).
  • Antiparasitic tablets : Oral medications that act quickly (sometimes in less than 4 hours) against severe infestations.

Tick ​​Removal

Use a tick hook or tweezers to remove them with a twisting motion. Improper removal (breaking off the head) can cause infection.

Always disinfect the area with an antiseptic after removal to limit the risk of disease transmission.

3. Treat the Environment for Complete Eradication

Parasites proliferate in the environment. A study (Cadiergues et al., 2011) demonstrated that 95% of fleas are found in the form of eggs, larvae or pupae in the house.

  • House cleaning : Vacuum all surfaces (carpets, rugs) and immediately dispose of the vacuum cleaner bag.
  • Washing textiles : Wash your dog's blankets, cushions and baskets at a high temperature (minimum 60°C).
  • Environmental treatments : Use specific sprays or fumigators containing insect growth regulators (IGRs), such as methoprene, to prevent the development of larvae and eggs.
  • Outdoors : Mow the lawn regularly and maintain the garden, as ticks thrive in tall grass.

4. Preventing Re-infestations of Fleas and Ticks

Prevention is essential for lasting protection (Fourie et al., 2015).

  • Regular parasite control : Apply pipettes, collars or tablets as recommended by your veterinarian for continuous protection.
  • Frequent inspections : Always check your dog's coat after walks, especially in **spring and fall**.

5. Natural Solutions (as a Supplement)

Natural alternatives can be used in addition to conventional treatments, but with caution.

  • Apple cider vinegar : A diluted solution can be sprayed on the coat to make it less attractive to fleas.
  • Essential oils : Lavender or geranium have repellent properties. Caution: some oils (like tea tree oil in high concentrations) can be toxic.
  • Diatomaceous earth : Applied to carpets or resting areas, it mechanically dehydrates fleas and their larvae.

6. When to Consult a Veterinarian?

Despite your efforts, a consultation is necessary in the following cases:

  • Signs of illness after a tick bite (fever, apathy, joint pain).
  • In cases of flea allergy dermatitis (FAD), which causes severe itching and secondary skin infections.

Conclusion

Managing an infestation requires a methodical approach: curative treatments, regular preventative measures, and strict environmental hygiene. Remember that your veterinarian remains your best ally in ensuring your dog's health and well-being in the face of these parasites.
