How Fleas Survive
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 on Pets
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 infection can develop and lead to more severe diseases if fleas are left untreated.
How to Check 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 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.
Other Issues That Could Be Causing Your Pet to Scratch
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.
How To Get Rid of Fleas on Pets
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.
