What are the most common skin parasites in dogs?

There are several different types of skin parasites that can affect dogs. Some of the most common include:

Fleas – Tiny wingless insects that feed on your dog’s blood. Fleas are very common and can infest both indoor and outdoor environments.

Ticks – Small arachnids that attach themselves to your dog’s skin and feed on their blood. Ticks are prevalent in outdoor wooded and grassy areas.
Mites – Microscopic insects that cause irritation and itching. Types of mites include sarcoptic mange mites, demodex mites, and ear mites.
Lice – Wingless insects that feed on skin and hair. Lice spread quickly through close contact with other dogs.

What are the signs my dog may have skin parasites?

Some common signs that your dog may be infested with skin parasites include:

Itching – Persistent scratching, licking, chewing, or nibbling at their skin or fur.
Hair loss – Patches of missing fur from excessive scratching and biting.

Redness – Red, irritated skin from repeated chewing and scratching.
Scabs and sores – Small lesions, scabs, and open sores caused by parasite bites or self-inflicted trauma from scratching.
“Hot spots” – Large, red, moist, irritated lesions that can develop from intense scratching.

Restlessness – Acting agitated and unable to settle due to itchiness and discomfort.
Skin crawling sensation – Some skin parasites can cause a “pins and needles” sensation in a dog’s skin.

Where on my dog’s body are parasites commonly found?

While parasites can infest any part of a dog’s body, there are certain areas that are more prone to parasites. Common parasite-prone spots include:

Paws – The paws are a hot spot for fleas, ticks, and mites.
Ears – Ear mites often take up residence in a dog’s ears.
Elbows – Fleas and mites frequently gather in elbow creases.

Armpits – Warm, moist armpits provide an ideal environment for parasites.
Belly – The soft, warm underside is attractive to parasites.
Groin – Fleas and ticks will nestle into a dog’s groin and upper thighs.

Face – Parasites may concentrate around a dog’s eyes, mouth, and muzzle.
Tail and hindquarters – Fleas love to congregate at the base of the tail and back legs.

How can I check my dog for skin parasites?

To inspect your dog for parasites, follow these steps:

Look closely through your dog’s fur for any signs of fleas, ticks, or lice. Check their bedding too.
Part the fur to examine the skin. Look for any irritation, redness, bite marks, dry skin, or parasites moving on the skin.
Check common parasite hot spots like the ears, armpits, paws, belly, and groin.

Use a flea comb to help spot fleas in your dog’s fur. Wipe a white paper towel below the comb to see any flea dirt or blood spots.
For mites, look inside the ear canals. Signs of ear mites include dark crumbly discharge.
Examine your dog’s skin under bright light. Mites and lice can be visible to the naked eye.

When should I take my dog to the vet?

You should make an appointment with your veterinarian if:

You find live parasites like fleas, ticks, or lice on your dog.
Your dog has signs of a parasitic skin infection, like hair loss, sores, or scabs.

Your dog is scratching, licking, or chewing intensely and unable to settle.
Your dog has symptoms of an allergic reaction, such as hives, swelling, or trouble breathing.
Home treatments do not eliminate your dog’s itching and skin irritation.

Your dog is lethargic, ill, or has a fever, which may indicate a secondary infection.

Skin parasites can make dogs extremely uncomfortable. A vet can diagnose the exact cause of the problem and provide safe, effective parasite treatment and relief for your dog.

How do vets test for parasites?

Veterinarians use a combination of tests to check dogs for parasites, including:

Physical exam – Closely looking over your dog’s skin and coat to spot any parasites or related skin damage.
Skin scrapings – Using a scalpel blade to collect skin cell samples, which are then examined under a microscope for mites.
Tape test – Sticking tape to your dog’s skin to pick up any parasite specimens. The tape is then placed on a slide for microscopic viewing.

Fur combing – Repeatedly combing your dog’s coat with a fine-toothed flea comb to collect parasite samples for identification.
Flotation test – Mixing a fecal sample with a solution that causes parasite eggs to float to the top for identification under a microscope.

Blood tests may also be recommended to check for antibodies to specific parasites or infections resulting from parasite bites. Your vet will suggest the most suitable tests based on your dog’s symptoms.

How are skin parasites treated and prevented?

There are many effective options for getting rid of parasites and stopping reinfestation, including:

Medicated shampoos and dips – Kills parasites inhabiting your dog’s skin and coat.
Spot-on and oral medications – Rapidly eliminates existing parasites and provides ongoing protection against reinfestation.

Antibiotics and anti-itch drugs – Treats any secondary infections causing itching or discomfort.
Flea and tick control products – Long-lasting monthly spot-on or collar treatments that repel and kill parasites.
Environmental treatments – Professional extermination or thorough cleaning of your home and yard helps remove parasite eggs and break the life cycle.

Grooming tools – Using flea combs and nitbrushes helps remove parasites from your dog’s coat.

Be sure to follow your vet’s instructions carefully regarding medication doses and treatment frequency. Consistent prevention is key to keeping parasites away.

Home remedies for skin parasites

There are a few natural remedies you can try at home to help get rid of mild cases of parasites:

Apple cider vinegar – The acidic vinegar disrupts parasite growth cycles when applied diluted to irritated skin.
Essential oils – Oils like tea tree, lavender, and citronella may help repel and kill some parasites when used in moderation.
Coconut oil – Smothers parasites and soothes itchy skin when applied topically.

Oatmeal baths – Soothes irritated skin and allows parasites to be combed out of your dog’s coat.
Yogurt – The probiotics help restore healthy skin flora to deter parasites.
Raw garlic – Contains anti-parasitic compounds when fed to dogs in small amounts.

While home remedies may provide some relief in mild cases, contact your vet if problems persist. Never use essential oils at full strength, and consult your vet first, as some ingredients can be toxic to dogs.

How can I prevent my dog from getting skin parasites?

You can help protect your dog from getting infested with parasites by taking these preventative steps:

Use monthly flea and tick control products recommended by your veterinarian.

Check your dog’s coat thoroughly for any signs of parasites at least once a week.
Ask your vet about parasite prevention before visits to places like dog parks, kennels or groomers.
Treat your home and yard regularly with parasite control products.

Vacuum and wash your dog’s bedding frequently using hot water.
Groom your dog regularly and discard any collected hair immediately.
Keep your grass cut short and clear piles of leaves/debris from your yard.

If outdoors, check your dog thoroughly for ticks after every walk.

Consult your vet if you are travelling to new areas with your dog, as they may recommend additional preventative medication before and during travel.

How do I choose a good parasite prevention product?

Look for these qualities when choosing parasite control products for your dog:

Kills adult parasites and inhibits eggs/larvae – Stops parasites at all life stages.
Waterproof – Remains effective after swimming or baths.
Lasts 30 days or more – Provides ongoing protection between doses.

Fast-acting – Quickly kills parasites present at time of application.
Veterinarian recommended – Ask your vet for suggested products best suited to your dog.
Easy to administer – User-friendly topical spot-ons, collars, pills or chews.

Prevents reinfestation – Continues repelling and killing newly introduced parasites.

Avoid over-the-counter products with ambiguous labeling and purchase parasite control products from trusted retailers. Follow all label directions carefully.

Flea and Tick Collars

Flea and tick collars provide ongoing protection by constantly emitting insecticides from the collar band. These collars:

Provide continuous parasite repelling action around neck and head.
Last for several months (check label for exact duration).
Come in adjustable sizes to fit most dogs.

Are water resistant.
Require no additional monthly application.
Can be used along with other flea/tick treatments.

Some potential drawbacks of flea collars include:

May cause skin irritation from plasticizers and residue.
Some dogs dislike wearing collars.

Can fall off if not properly fitted.
Only protect neck/head region.
May transfer insecticides onto human hands.

So while flea and tick collars can help control parasites, they may work best paired with an additional form of treatment.

Spot-on Treatments

Spot-on parasite treatments involve applying a liquid medication directly onto your dog’s skin, usually between the shoulder blades. These monthly treatments:

Rapidly kill existing fleas, ticks, and other parasites.

Maintain effectiveness after swimming or bathing.
Spread over body via skin oils to protect entire coat.
Come in easy-to-use pipettes, tubes, or single dose applicators.

Last for 30 days or longer before reapplication is needed.
Are available from veterinarians or over-the-counter.

Some potential cons of spot-on treatments are:

Can cause skin irritation in some dogs.
Odor may be unpleasant to some owners.
Must be carefully applied to avoid ingestion.

Monthly reapplication is essential.

When used as directed, spot-ons provide comprehensive ongoing parasite protection for dogs.

Oral Medications

Oral parasite prevention medications for dogs typically come in chewable tablet form. Oral treatments offer these advantages:

Provide full-body parasite protection.
Are easy to give alongside food.
Appealing meaty flavors.

Last for 30 days or longer.
Available over-the-counter or from vets.
Waterproof protection.

Some possible downsides of oral parasite meds include:

Must be given regularly each month.
Some dogs dislike taking tablets.

May cause gastrointestinal side effects in some dogs.
More expensive than some topical treatments.

But overall, oral parasite medications are an easy and effective preventative option for dogs when used properly.
