If your dog has been flea dipped, given a flea bath or had a topical flea treatment applied, the result can be dead fleas in your dog's fur. Thorough and repeated brushing and flea-combing can help ensure your pup is dead flea free.
Eradicating fleas, particularly a heavy infestation, is a multistep process. Some flea removal products, such as diatomaceous earth, which gradually dries up fleas, can take up to a week to work. Other flea removal products, such as medicated shampoos, powders and ointments, kill fleas on contact. Whatever method you're using, follow treatment with a vigorous brushing to get into under layers of fur, particularly with dogs who have double coats, such as Labradors.
The Fine Details
Use a fine-tooth comb or flea comb to pick up dead fleas the brush misses. Keep a bucket filled with soapy water near you so you can dip your brush or comb and remove the dead fleas and hair. Use a water-dipped cotton ball to clean around your dog's eyes, and in his ears. Unscented baby wipes can help remove dead fleas from sensitive areas, such as the groin region.
Part of the flea eradication process includes washing all flea-infested bedding to ensure fleas, eggs and larvae are eliminated. It doesn't do any good to treat your dog for fleas only to have him sleep in his dog bed and become re-infested the next day. To ensure your entire household is clean of fleas, sweep floors and vacuum carpets and upholstery furniture.
Prevent Future Outbreaks
Talk to your vet about an appropriate flea preventive to keep your dog from contracting fleas in the future. Use all over-the-counter flea products carefully. Pay close attention to dosing guidelines per your dog's weight.
