Veterinarians say pet owners dealing with fleas should treat the problem as both a medical and household issue. NBC Selected reported that experts recommend a three-part approach: confirm the infestation, treat and prevent it, then clean the home to reduce the chance of repeat outbreaks.
Dr. Jennifer Garner, a veterinarian at Chewy Vet Care, told NBC Selected that skipping parts of the process can leave pets exposed to reinfection and homes open to another infestation. The outlet said year-round flea prevention is recommended by veterinarians, though owners should talk to their own vet because some products require prescriptions.
How owners can confirm fleas
NBC Selected said a flea comb is a key tool for checking a cat or dog. Fine teeth help separate fur so owners can look at the skin and hair follicles for fleas or flea dirt, which the outlet described as flea feces.
The guide listed the Pets&Goods Flea Remover Comb as its flea-comb pick and said such combs can also remove eggs and debris from pets’ coats. NBC Selected said some cases may still require a veterinarian visit to confirm the problem.
Treatment and prevention options
NBC Selected said it included oral, topical and collar products that matched expert guidance, had strong ratings, worked as both treatment and prevention, protected against multiple parasites and were approved by the Environmental Protection Agency or Food and Drug Administration. The outlet cautioned that several flea medications are prescription-only.
For dogs, NBC Selected listed NexGard Chewables, an FDA-approved oral product containing afoxolaner. According to the outlet, the chews begin working within four hours, last one month and are approved for dogs at least 8 weeks old and 4 pounds; the product requires a veterinarian’s prescription.
For cats, NBC Selected listed Credelio for Cats, a prescription chew containing lotilaner. The outlet said it starts working within six hours, lasts one month and is made for cats at least 8 weeks old and 2 pounds, with doses based on weight.
NBC Selected also highlighted Frontline Plus topical treatments for both dogs and cats. The outlet said the dog version contains fipronil and (S)-methoprene, starts working within 24 hours and lasts 30 days, while the cat version uses the same active ingredients, starts working within 12 hours and also lasts 30 days.
Collars and cleaning
The guide also listed Seresto collars for dogs and cats. NBC Selected said the dog collar contains imidacloprid and flumethrin, begins working within 24 hours and lasts eight months; the dog version is sold in sizes for pets under 18 pounds and over 18 pounds.
NBC Selected named Adams Plus Flea & Tick Shampoo as a shampoo option and Wondercide Natural Flea, Tick & Mosquito Spray as a cleaning spray option. The outlet framed cleaning as the third part of flea control, after diagnosis and medical treatment or prevention.
Garner’s warning, as reported by NBC Selected, was that flea control can fail when owners handle only part of the problem. The practical message from the veterinarians cited by the outlet: check the animal, use an appropriate vet-approved product and clean the pet’s environment before fleas can cycle back.
