Few things are as frustrating for a dog owner as dealing with fleas. These pests can cause painful bites and sometimes transmit diseases. While an infestation is irritating, it is manageable, and with some effort, it can be treated and prevented.
Understanding Fleas
The first step in dealing with fleas is understanding their lifecycle. Fleas are small, flightless insects that survive on blood. They are visible to the naked eye, but on dogs with dark fur, you might need to look closer at the skin to spot them.
Lifecycle and Irritation
A flea goes through four stages in its lifecycle: egg, larva, pupa, and adult. Adult females lay eggs in batches of 20, usually on the host, but these eggs quickly fall to the ground. The eggs are tiny, oval-shaped, and white or gray.
When the eggs hatch, larvae emerge and feed on debris like feces, dead insects, or vegetable matter. Within a week or two, the larvae spin cocoons and pupate for another one to two weeks. Adult fleas then emerge and must find a host for blood immediately.
Fleas typically specialize in a particular host. The fleas on your dog usually won’t feed on humans, though exceptions exist.
Prevention
Preventing a flea infestation is far better than trying to eliminate one. Unfortunately, it’s hard to predict the source of an infestation until it happens.
Vacuuming thoroughly, especially in nooks, crannies, and on upholstered furniture, helps remove eggs, larvae, and cocoons. Fleas often enter your home via your dog, especially after trips to infested areas. If your dog gets fleas after visiting a particular location, bathe and comb him when you return. Use a fine-toothed comb and soapy water to drown the fleas.
If the infestation source is your front lawn, extra precautions during flea season are necessary.
Spotting the Signs
Signs your dog has fleas include excessive scratching or biting, developing a rash, or finding eggs or flea dirt (dark, hard pellets of digested blood) in his fur or bedding.
Treatment
Your vet can recommend treatments to quickly eliminate fleas and their eggs. These treatments typically kill adult fleas or weaken larvae, turning your pet into a walking flea death trap. Since treatments often target only one life stage of the flea, supplementing with diligent cleaning of your dog’s bedding is crucial.
Be cautious with flea treatment products not provided by your vet. Always consult with your vet before starting any treatment on your pet.
