How Can I Tell if My Cat or Dog Has Fleas?

How Can I Tell if My Cat or Dog Has Fleas?

Fleas are the most common external parasite, and they can make your pet miserable and can lead to infections and cause serious diseases. Our Port Jefferson vets explain how fleas are detected and treated in cats and dogs.

Fleas in Cats & Dogs

Fleas are external parasites that rely on a host animal for survival. Unless steps are taken to break their lifecycle, adult fleas will continue to reproduce and thrive on your pet - and in your household. 

Signs of Fleas in Cats & Dogs

Cats and dogs may be allergic to the protein in flea saliva, which is why they often start to scratch as soon as a flea bites their skin. Even one flea bite may cause pets to scratch excessively and become agitated. 

Besides scratching, red bumps or pimples may appear on their belly, at the base of their tail or on their behind, on their groin, or under their legs. The constant itching and scratching of these areas will cause dry skin and hair loss. Lesions and infections can develop and lead to more severe diseases if fleas are left untreated. 

Checking Your Pet for Fleas

Adult fleas are small and brown. They are relatively easy to spot with the naked eye. 

It's a good idea to check your pet's brush or comb while you're grooming them. Having your pet lie on its side will let you have a closer look at areas with thin hair, such as the abdomen. 

You may see "flea dirt". This looks similar to tiny grains of sand, or black pepper when wet. To check for flea dirt (feces), use a fine-tooth flea comb available at your vet's office to comb along your pet's back and underbelly. By standing your pet on a white towel or cloth while brushing them, you will be able to easily see any black droppings that fall from their fur. 

What to Do if Your Pet Is Scratching, but You Don't See Fleas

If there are no signs of fleas but your pet is still scratching, schedule an appointment with your vet, who can administer a skin test to check for flea allergies, in addition to other types of allergies during your visit. Your pet may be reacting to another type of allergy that's making them uncomfortable.  

Treating Fleas in Cats & Dogs

Several safe and effective treatments can be used to eliminate fleas, including shampoos, sprays, powders, and topical liquids. You may need to visit your vet for prescription creams and antibiotics if your pet's case is more severe. 

Early treatment and prevention are the first methods of choice to ensure your dog doesn't develop more serious issues in the future, as a result of fleas.

Preventive measures can be quite effective in ensuring your pet will not contract fleas in the first place.
