How dog flea pills work?

Remember that anti-flea pills for dogs work as a preventative solution against parasites. They’re administrered orally once a month and don’t allow new parasite eggs to hatch on your canine.

“When an adult female flea bites a Program-treated dog or cat, the flea ingests the active ingredient (lufenuron) which then passes into her eggs and prevents them from hatching.” – Michael F. Potter, Extension Entomologist (source)

Fleas and similar pests that attack dogs are also dangerous to humans and can negatively affect our health. Kansas State University created a quick guide on fleas and other pests as they relate to dogs and humans which you can read here (PDF).

“What if my dog already has fleas?”

If your dog is already infested with fleas, check out this quick video guide on how to remove fleas from a dog. Samantha has covered everything from preventing fleas to removing them from the dog and within the house, including the best solutions (store bought and homemade).

Ultimately, prevention is the best way to fight off fleas on dogs. So once you remove them, ensure that your pooch is protected for the future.

Many preventative measures (such as dog flea collars, flea sprays and topical flea treatments) only ward off fleas and ticks. The best flea pills for dogs will also keep your pet safe from other parasites including heartworms and intestinal parasites.

Best Flea Pills for Dogs

1Merial Frontline Plus Flea and Tick Control

Merial Frontline Plus Flea and Tick ControlFrontline Plus is a monthly anti-flea topical treatment for prevention of fleas, ticks and lice. It is manufactured by Merial and claims to be able to kill 100% of all fleas on your pet within 18 hours and 100% of all ticks within 48 hours. Easy to administer and waterproof for 30 days, Frontline Plus offers hassle-free parasite control.

It seems that dog owners either love Merial Frontline Plus Flea and Tick Control or hate it. Those in the ‘hate it’ camp have found that it doesn’t work, is ineffective after 3 weeks or that recent batches haven’t worked. This may be due to milder temperatures providing perfect breeding conditions for flea and tick population, a change in the drug’s formula or perhaps no managing the flea lifecycle in the home environment.

Some dogs have had allergic reactions to Frontline anti-flea treatment, ranging from mild lethargy and skin irritation to severe chemical burns and extreme sickness and diarrhea. This has understandably created a mistrust of this type of topical treatment for some owners. To reduce the chance of an allergic reaction with any of the best flea pills for dogs, it is advisable to discuss your dog’s risk factors with his vet prior to commencing treatment.
