Dear Dr. Suzi:

My dogs and cats are scratching a lot. I suspect fleas. What should I do?

Dear Buzz:

Itchiness is symptomatic of any number of different conditions, so I always recommend that you consult your veterinarian for diagnosis.

Outdoor—and even indoor—pets can become flea infested, especially during the warmer months. Fleas can live six months to a year, and during that time, they can produce millions of offspring. They may be difficult to spot, as they spend relatively little time on the pet. Flea droppings (dark particles) embedded in the pet’s coat are a sure sign of their presence.

Fleas can cause reactions in pets ranging from mild skin irritations to severe allergic reactions. It is essential to have 100 percent flea control in order to eliminate itching in allergic pets. Even one or two bites a week perpetuate the itching. Fleas feed on blood, so severe infestations can cause anemia or even death in very small or debilitated animals. Fleas can also transmit diseases to pets AND people.

NOT RECOMMENDED: Flea shampoos and collars are ineffective. Fleas can jump right back on the pet once the shampoo is rinsed off. Collars do not provide enough coverage to kill or repel fleas from the whole body.

RECOMMENDED: Veterinarians can prescribe many topical products that provide excellent protection for up to one month. Be careful to use the products as directed, as some are specifically for dogs and can be very dangerous if used on cats. It’s important to treat all the pets in a household, not just the itchy ones. Treating the environment is also important in controlling fleas. Check with your veterinarian as to which products are safe for home and yard use.
