Signs That a Pet Has Fleas

Fleas not only are annoying and hard to get rid of, but they also can carry disease. These blood-sucking insects are the most common external parasite found on dogs and cats, according to the Companion Animal Parasite Council. They are most likely to be a problem during the warm months, but don't let your guard down during cooler seasons. Look for the telltale signs that your pet is having a flea problem and treat accordingly.

  1. Chewing &Scratching

    • Take note if your pet chews and scratches his skin.

      The first sign of a flea problem is your pet's repeated chewing and scratching on its skin. Constant scratching can lead to patches of hair loss, as well as red, irritated skin. Fleas also can cause skin allergies. Look at the area that is bothering your pet, as well as its belly where the fur is thinner -- you might see a flea moving through its coat. It will be about the size of a small grain of rice and a dark brown or black in color.

    Flea Dirt

    • Check your pet thoroughly for flea dirt -- which is flea feces. This is one of the most accurate methods in detecting a flea problem, as it is not always easy to find the fleas themselves. Have your pet stand or sit on a white piece of paper and comb or rub through a section of hair. Black flecks that look like dirt will fall from the fur. Transfer the dirt to a moist piece of paper. Flea dirt will turn red or rust-colored in a short time. The color is a result of the blood sucked from your pet. If the dirt does not turn red, it's just plain old dirt.

    Check Yourself

    • Look for flea bites on your own body. If you find them, it's likely that fleas are in your home or yard and on your pet. A simple way to test for fleas is to walk around in a pair of white socks. If fleas are present, chances are good you will collect a couple and they will be easy to see on the white fabric.

    Related Problems

    • Fleas are linked to a host of other health problems.

      Take note of other health problems your pet is having -- these might be caused by fleas. Fleas are disease carriers and linked to a host of problems including flea allergy dermatitis, tapeworms and anemia. Contact your vet immediately for a diagnosis and treatment options.
