How to prevent from external Parasites for Pets Dogs in Nepal

“A dog is the only thing on earth that loves you more than he loves himself.”– Josh Billings

Nepal has a diverse climate due to its varying topography, ranging from the lowlands of the Terai to the high Himalayan mountains.  It’s important to note that the prevalence of external parasites can also be influenced by factors like local animal husbandry practices, urbanization, and changes in climate patterns due to global warming. The climate can be broadly categorized into subtropical, temperate, and alpine zones.

  1. Subtropical Zone (Terai): This region has a hot and humid climate during the summer (March to June) with temperatures reaching above 35°C (95°F). The monsoon season, from June to September, brings heavy rainfall and warm temperatures. These conditions can be favorable for the proliferation of external parasites like fleas, ticks, and mites, which can affect both pets and livestock.
  2. Temperate Zone (Hills): The temperate regions of Nepal experience distinct seasons – a hot summer, a monsoon season, and a cool winter. In these areas, the climate is milder compared to the Terai. The rainy season can create a humid environment, which might be conducive to the growth of parasites. During the colder months, the risk of some external parasites might decrease due to lower temperatures.
  3. Alpine Zone (Mountains): In the high-altitude regions of Nepal, the climate is generally cold and harsh. The extreme cold temperatures might limit the survival and reproduction of many external parasites. However, certain parasites adapted to colder environments could still pose a threat to animals living in these areas.

External parasites, such as fleas, ticks, mites, and lice, can indeed cause a range of problems for pets, including skin irritations, allergic reactions, and the transmission of diseases. Here’s how these issues can arise:

  1. Skin Irritations: Parasites like fleas and ticks feed on the blood of their host animals, including pets. Their bites can cause intense itching, redness, and inflammation. Pets may scratch, bite, or lick the affected areas, leading to broken skin, hair loss, and secondary infections. This constant irritation can cause discomfort and distress for the pet.
  2. Allergic Reactions: Some pets are allergic to the saliva of parasites like fleas. When bitten, these pets can develop an allergic reaction known as flea allergy dermatitis (FAD). Even a single flea bite can trigger a strong allergic response, causing severe itching, redness, and hair loss. Pets with FAD can develop extensive skin lesions and secondary infections due to their constant scratching and biting. 
  3. Transmission of Diseases: Parasites can carry various diseases that can be transmitted to pets through their bites. For instance:
    • Ticks: Ticks can transmit diseases such as Lyme disease, Rocky Mountain spotted fever, and Ehrlichiosis. These diseases can lead to symptoms like fever, joint pain, lethargy, and even organ damage in severe cases.
    • Fleas: Fleas can transmit tapeworms, which are intestinal parasites. Pets can ingest infected fleas while grooming themselves, leading to tapeworm infestations. Symptoms can include weight loss, scooting, and visible segments of tapeworms in the pet’s feces.
    • Mites: Mites like Sarcoptes scabiei can cause mange, a condition characterized by intense itching, hair loss, and skin lesions. Demodex mites can also cause localized or generalized demodectic mange. Some mites can transmit zoonotic diseases, meaning they can be transmitted from pets to humans.
    • Lice: While less common, lice infestations can cause itching, redness, and discomfort for pets. Heavy infestations can lead to hair loss and skin infections.

In severe cases, untreated infestations of external parasites can compromise a pet’s overall health and well-being. Some pets may become anemic due to the constant blood loss caused by parasites like fleas. Secondary bacterial or fungal infections can develop due to the broken skin resulting from scratching and biting.


Caring for pets and preventing external parasites like fleas, ticks, and mites is crucial to ensure your pet’s health and well-being. Here are some steps you can take for pet care and parasite prevention in Nepal or any other region:

  1. Regular Grooming: Brush your pet’s fur regularly to remove dirt, debris, and potential parasites. Grooming also helps you notice any changes in your pet’s skin or coat.
  2. Bathing: Give your pet a bath using a pet-approved shampoo. Be cautious not to bathe them too frequently, as it can strip their skin of natural oils. Follow the recommended bathing schedule for your pet’s breed and type.
  3. Check for Parasites: Regularly inspect your pet’s fur and skin for any signs of external parasites like fleas, ticks, or mites. Look for redness, itching, or small black/brown spots on their fur.
  4. Tick and Flea Prevention: Use veterinarian-approved tick and flea prevention products. These can come in the form of topical treatments, collars, or oral medications. Consult your vet to determine the most suitable option for your pet.
  5. Clean Living Spaces: Keep your pet’s living area clean and vacuumed regularly. Wash their bedding, toys, and other belongings frequently to prevent parasite infestations.
  6. Landscaping: Trim grass and bushes in your yard to reduce the chances of ticks and fleas in the environment. Create barriers to prevent wild animals from entering your yard and potentially bringing parasites with them.
  7. Tick Checks: After outdoor walks or playtime, carefully check your pet’s body for ticks. Pay attention to areas like ears, neck, and paws where ticks often hide.
  8. Regular Vet Visits: Schedule regular veterinary visits for check-ups and vaccinations. Your vet can also recommend specific parasite prevention measures based on your pet’s health and lifestyle.
  9. Proper Nutrition: Feed your pet a balanced and nutritious diet to maintain their overall health and strengthen their immune system. A strong immune system can help pets fend off parasites more effectively.
  10. Consult a Veterinarian: If you suspect your pet has external parasites or if you’re unsure about prevention methods, consult a veterinarian. They can provide specific guidance based on your pet’s needs.
  11. Avoid Overcrowded Areas: In places where parasites are more common, avoid taking your pet to overcrowded areas with tall grass and bushes where parasites thrive.
  12. Use Pet-Friendly Pesticides: If you use pesticides in your home or yard, make sure they are safe for pets. Consult your vet or a pest control professional to find suitable options.

Remember, prevention is key when it comes to external parasites. Regular care and vigilance can help you keep your pets healthy and happy by avoiding infestations and related health issues.
