Ticks and Fleas in Dogs: Signs, Treatment and Prevention in India

Ticks and fleas in dogs are common blood-feeding pests in India, all year round, not only in the monsoon. You can usually spot them with a weekly coat check. The most reliable way to clear and prevent them is a vet-prescribed product given on time, every time, along with cleaning your dog’s bedding and home.

This guide explains how to tell ticks from fleas, how to remove a tick safely, how vets treat and prevent them, which home remedies to avoid, and when your dog needs to see a vet.

Ticks and fleas are tiny parasites that live on the skin and feed on blood. A few bites cause itching and irritation. Larger numbers can lead to skin infections and, especially in puppies and small dogs, blood loss (anaemia). Some ticks and fleas can also pass on infections.

What Indian research shows:

• Ticks are common. A study of 525 dogs across Sikkim, Ladakh, Delhi and Mumbai found ticks on about half of them, and about half carried at least one tick-borne infection. These were mostly stray, shelter and village dogs sampled in 2008, so the figure for well-cared-for pet dogs today is likely lower, but it shows how widespread ticks are.

• The “cat flea” is the main flea on dogs. In a study of dogs in Mumbai, Delhi and Rajasthan, about 9 in 10 fleas were the cat flea, so a dog can have “cat fleas” even in a home without cats.

• Fleas can pass tapeworm. A dog can swallow an infected flea while grooming. See our guide to worm signs in dogs.

Ticks can also spread tick fever, a group of blood infections that vets in India see often. It is treatable, especially when found early.

Ticks are larger and stay attached in one place. Fleas are tiny, dark, and move and jump quickly. Many dogs have both.

Flea dirt test: comb your dog over a white paper towel and add a few drops of water to the black specks. If they turn red-brown, it is flea dirt (digested blood). This confirms fleas even when you cannot see a live one.

• Brown dog tick: the most common tick on Indian dogs. Unusually, it can complete its life cycle indoors, so it can settle into homes, kennels and apartments in any season.

• Other ticks: other tick types are found in some regions. Your vet will know what is common where you live.

• Cat flea: the main flea on dogs in India.

• Lice: a different parasite again. Lice are tiny and glue their eggs (nits) to the hair, and need their own treatment. See our guide on lice in dogs.

Many dogs show nothing at first. Often the first clue is a dog that keeps scratching, licking or chewing its skin. A quick coat check once a week, even when your dog seems fine, catches most problems early.

• Scratching, biting or licking the skin repeatedly

• Small bumps, scabs or red patches, often on the ears, neck and paws

• Black specks in the coat that turn red-brown when wet

• Hair loss near the base of the tail and back legs

• A tick or flea you can see, or a swollen tick on the skin

• Small white rice-like bits near the tail (these can be tapeworm segments)

• Tiredness, pale gums or poor appetite (possible signs of blood loss or infection)

Itching has many causes, including allergies, mange and skin infections. These symptoms can be associated with ticks and fleas, but they are not proof. If scratching continues after flea treatment, read why a dog keeps itching and scratching and ask your vet to examine the skin.

• Physical examination: the vet checks the coat and skin, often with a flea comb, and looks at gum colour and body condition.

• Skin tests: if the itching may have another cause, the vet may take skin scrapings or tape samples to look for mites, yeast or bacteria.

• Blood tests: a complete blood count shows anaemia and low platelets, which are common in tick fever. Rapid kit tests or PCR tests can identify specific tick-borne infections.

• Stool test: to check for tapeworm and other worms.

Use fine-tipped tweezers or a tick remover tool. Grip the tick close to the skin and pull straight out with slow, steady pressure. Do not squeeze, twist or burn it. Clean the spot afterwards.

1. Wear gloves, or wash your hands afterwards. Keep your dog calm.

2. Part the fur and grip the tick as close to the skin as you can.

3. Pull straight up, without twisting or jerking.

4. Drop the tick into a small jar of rubbing alcohol. Do not crush it with your fingers.

5. Clean the bite with soap and water, and wash your hands.

6. Check the spot over the next few weeks. If mouthparts stay in the skin or the area looks sore, ask your vet.

Removing one tick is only a start. Where there is one, there are usually more. Check the whole body, and speak to your vet about starting a prevention product. See our step-by-step guide to spot and remove ticks, and keep a tick remover in your pet first aid kit.

Treatment depends on your dog’s age, weight, health and home. The main options are tablets or chews, spot-on drops, sprays, collars and medicated shampoos. They differ in how long they protect and how they are given.

Tablets and chews have the strongest evidence for controlling both ticks and fleas, and many vets choose them first. Spot-ons are also effective. Sprays and shampoos work best alongside a longer-acting product, not instead of one. You can browse each type here: tick and flea products for dogs, tick and flea tablets, spot-ons, tick collars, and tick and flea shampoo. Prescription products need a vet's prescription for your dog's current weight, and if your vet picks a product we do not sell, follow your vet.

The interval matters as much as the product. Give the next dose on the date your vet gives you. A dose given late leaves a gap with no protection. A dose repeated early does not add protection, and may not be safe.

If your dog is diagnosed with tick fever, treatment is different from prevention: it usually involves antibiotics or antiprotozoal medicines prescribed by a vet, sometimes for several weeks, along with supportive care, depending on the infection and how unwell your dog is.

There is no single best tablet for every dog. The right one depends on your dog’s weight, age, health and medical history. Most modern tick and flea tablets belong to one medicine family called isoxazolines. They start working within hours and are given monthly or every few months, depending on the product.

• Safety: the US FDA considers isoxazolines safe and effective, and most dogs take them without any problem. In rare cases they have been linked to muscle tremors, wobbliness or seizures, so tell your vet if your dog has ever had a seizure or another neurological condition.

• Age and weight: each product has its own minimum age and weight.

• Pregnant or nursing dogs: your vet will advise.

• Prescription: these are prescription medicines. Your vet prescribes the right product and strength for your dog’s current weight.

Some sprays, shampoos and powders do not need a prescription. Most tablets, and many spot-ons, are prescription-only medicines, because the right product and strength depend on your dog’s weight, age and health. Even for non-prescription products, a vet’s advice helps you avoid the wrong choice, especially for puppies, pregnant dogs and homes with cats. You can talk to a vet online, or visit a Supertails clinic in Bengaluru.

A tick and flea spray kills parasites it touches, so it can help with a quick clean-up or as a top-up. It does not protect your dog for a full month. Follow the label, keep spray away from the eyes, nose and mouth, and stop your dog licking the coat until it is dry. Many household sprays are made for floors and bedding, not for use on the dog, so read the label first. Compare options in our tick and flea sprays.

See a vet soon if:

• Itching or skin problems continue or get worse despite treatment

• Your dog keeps scratching, licking or chewing the same area

• You keep finding ticks or fleas even though your dog is on a product

• Your dog is eating less or has unexplained weight loss

• Your dog seems unusually tired

Seek urgent veterinary care if your dog:

• Is very weak, collapses or cannot stand

• Has pale or white gums, bruising, or a nosebleed

• Has difficulty breathing

• Has tremors, twitching or a seizure, including after a tick or flea product

• Has rapidly developing facial swelling after a product or a bite

• May have swallowed a product, or licked a freshly treated pet

These signs can be associated with tick fever, blood loss or a reaction, all of which are treated best when caught early.

These steps are supportive only. They do not cure an infestation or tick fever, but they help keep your dog comfortable and give your vet useful information:

• Flea comb: a fine-toothed dog comb removes live fleas and flea dirt. Dip it in soapy water to kill what you catch.

• Check daily during the monsoon: run your hands over the ears, neck, armpits and toes after walks.

• Bathe with a gentle dog shampoo: this cleans the coat but does not prevent new parasites. See how to bathe a dog at home.

• Wash bedding and blankets in hot water.

• Keep notes and photos: note when you first saw ticks or fleas, and photograph any skin changes.

• Do not start several new products at once. It makes reactions hard to trace.

There is no good evidence that any home spray or oil controls an infestation, and some are dangerous. Dogs lick their coats, so anything applied to the skin can be swallowed.

• Putting oil, alcohol, kerosene, nail polish or a lit match on an attached tick

• Giving a product made for a different weight band, splitting pipettes, or sharing one product between pets

• Using a dog product on a cat

• Repeating a dose early because you have seen a tick

• Letting other pets lick a freshly treated pet’s coat

Most of a flea problem is not on your dog. Eggs, larvae and pupae live in bedding, carpets and floor cracks, and flea pupae can wait for months before hatching. Brown dog ticks hide in wall cracks and behind furniture.

• Keep every dog in the home on a vet-prescribed product, so new fleas die when they bite.

• Wash bedding, covers and soft toys in hot water. Vacuum sofas, carpets, floor edges and under furniture often, and empty the vacuum outside.

• Check wall cracks, skirting and curtains for ticks.

• Treat every pet in the home at the same time, with a product suited to each species.

• Be patient: clearing fleas from a home often takes 4 to 8 weeks, sometimes longer.

• For heavy indoor tick problems, call a pest-control service. Tell them you have pets, ask for pet-safe products, and keep pets out until the area is safe.

Our guide on fleas in dogs has more on clearing the home.

The key is year-round prevention with a vet-prescribed product, given on time. Because the brown dog tick can live indoors, stopping in winter gives it a chance to settle in. One study in Guwahati found ticks on about 71% of dogs in the monsoon and about 37% in winter: fewer, but far from none.

Patterns vary by city, so follow your vet’s advice for where you live. See our guide to monsoon skin problems in dogs.

1. Note your dog’s next dose date and set a phone reminder.

2. Do a full-body check once a week: ears, neck, armpits, toes and tail base.

3. Wash your dog’s bed every week or two.

4. Keep balconies, gardens and corridors free of leaf litter and damp corners where ticks hide.

5. Keep up with deworming, since fleas can pass on tapeworm.

Give it as soon as you remember, unless your vet or the label says otherwise, and never give two doses together to catch up. Count the next date from the day you gave it. If you missed it by several weeks, check your dog for ticks and fleas and ask your vet what to do next.

Yes. Ticks can pass on tick fever, and fleas can pass on tapeworm. Heavy infestations can cause anaemia, and flea bites can trigger skin allergies. See a vet if your dog is weak, has pale gums or stops eating. Early treatment makes a big difference.
