How can I tell if my cat or dog has fleas?

How can I tell if my cat or dog has fleas?

Fleas are by far the most common external parasites found on pets. If not properly treated, they can make your pet miserable and can lead to infections and cause serious diseases. Our McAllen vets want to explain the signs of fleas and what to do if an infestation is starting.


What are fleas?

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. 

What signs of flea infestation should I look for?

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, 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. 

How can I check my pet for fleas?

Adult fleas are small and brown and depending on the length of your pet's fur, 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 their 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 if I can’t find any fleas, but my pet is still scratching?

If there are no signs of fleas but your pet is still scratching, schedule a dermatology 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.  

If my cat or dog does have fleas, how do I get rid of them?

A number of 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.
