How to Recognize Fleas in Dogs

Fleas are common parasites that can cause severe itching and discomfort for dogs. Not only are fleas troublesome and hard to treat, but they also pose a serious threat to your dog’s health if left unaddressed. In most cases, you can identify if your dog has fleas by observing their behavior, checking their coat for fleas or flea dirt, or looking for signs of flea activity.

Pay attention if your dog is scratching or biting excessively. Flea bites cause intense itching, so the first sign that your dog might have fleas is often increased scratching and biting.

• Other signs include frequent head shaking, hair loss, scabs, or warm spots on the skin.

Inspect your dog's skin for tiny, red spots that may appear. Flea bites are usually smaller than bites from other pests, which makes them harder to spot, so be sure to check carefully.

• In some cases, dogs may have a stronger reaction to flea saliva, causing the affected area to swell and irritate more.
• You may also notice red spots on your own skin from flea bites.

Examine your dog's fur to find any adult fleas. Use your hands to part the fur and check the skin underneath for signs of adult fleas. Fleas typically concentrate at the base of the tail, the belly, and behind the ears, but they can also crawl all over your dog.

• Adult fleas are about the size of a pencil tip. They are small, flattened insects ranging in color from reddish-brown to black.
• Note that fleas may try to escape when you part the fur, so spotting them might be difficult.
• Most fleas live in the environment around your dog, so you may have trouble finding them on your dog if the infestation is moderate.

Have your dog stand on a white towel while you brush its fur. Fleas will be disturbed when you brush your dog's fur. If they jump off, you'll be able to see them fall onto the white towel.

Use a flea comb and soapy water to check for flea feces on your dog's coat. Place the flea comb on your dog's fur and gently press it down until it reaches the skin. Carefully comb through your dog's fur, ensuring the teeth of the comb are in contact with the skin.

• After each pass, check the comb for fleas or flea droppings, then dip the comb in a bowl of soapy water to clean it.
• Flea droppings look like tiny black specks but actually contain dried blood. These specks will turn reddish when placed in soapy water.
• If the specks stay black in the water, they are probably just dirt.
• You can also place the specks on a damp cotton ball and monitor if they turn red. If they spread out like rusty iron stains, it’s a sign of flea feces.

Check your dog's gums to see if they appear pale. Pale gums may indicate anemia, a condition caused by blood loss from flea bites.

• Other symptoms of anemia include low body temperature and a lethargic appearance.
• Anemia from flea bites is particularly dangerous for puppies and small dogs.

Examine the area where your dog's food bowl and bed are located for flea droppings. If you find tiny black specks on your dog's bed, use a clean, damp white cloth or paper towel to wipe it. If the specks turn red after a few minutes, it's flea feces.

• Check around the dog's resting area, the food bowl, and any other places where the dog often lies.
• You may also spot adult fleas in these areas.

Put on white socks and walk near your dog's resting area. Fleas or flea droppings, if present, will stick to the socks, making them easy to spot.

Create a light trap using a bowl of water and a nightlight. Place a bowl of soapy water on the floor near your dog's resting place and turn on a nightlight. Fleas nearby will be attracted to the light, jumping into the soapy water and drowning.

• You may want to place your dog in a crate or in a different sleeping area overnight to prevent it from drinking the soapy water.

Consult with a veterinarian if your dog has fleas. The veterinarian will develop a specific plan to help you manage the flea infestation in your home. You will need to treat all pets, including both indoor and outdoor cats.

• Common flea treatment options include: monthly spot-on treatments, flea shampoos, sprays, and powders.
• It's important to create a specific plan for your dog and its surrounding environment, as some products may be toxic to pets when used together.

Try natural methods to eliminate fleas. Available sprays and powders can be effective products for killing fleas on your dog, its bedding, and throughout the house. You can also prevent fleas from attaching to your dog by dipping its comb in lemon juice before brushing its fur.

Thoroughly clean your home. You'll need to vacuum and wash all carpets, bedding, and fabric-covered furniture to remove fleas and their eggs.

• To prevent fleas from returning, make sure to wash your dog's bed at least once a week.

Use flea sprays or foggers in severe cases. These chemicals can be dangerous, so only use them when all other flea control methods have proven ineffective.

• Some flea treatments come in spray form, while others are foggers that release the chemical after activation, allowing you to leave the house and avoid exposure to the chemicals.
• Wear a mask to protect yourself when using chemicals, or hire a professional service to handle the flea treatment in your home.
• You’ll need to temporarily vacate your home during the flea treatment, so plan ahead to protect your dog and other pets. Usually, you’ll need to stay out for 3-6 hours, but always read the product label for safety instructions.

Trim the grass in your yard once a week to keep it from growing too tall. This will help prevent fleas from jumping onto your dog when it plays on the grass.

• Fleas prefer dark areas. Keeping your grass short will expose fleas to sunlight, making it harder for them to spread in your yard.

• Vacuum your home at least 1-2 times a week to reduce the risk of flea infestation. This method can help remove fleas, larvae, eggs, and pupae from carpets and upholstery.

• Wear a mask when spraying flea treatment products, or hire a pest control service to handle the treatment.
• Do not use flea treatments meant for cats on dogs.
