Frontline Gold for Dogs doesn’t just kill adult fleas and ticks, but also slays the next generation of flea eggs and larvae. Even faster than Frontline Plus, Frontline Gold starts working within 30 minutes and lasts for 30 days! It works because of two, tough killing ingredients. The first, fipronil, kills adult fleas and ticks. The second, (S)-methoprene, attacks flea eggs and larvae. They work together to kill all month long. Plus, it breaks the flea life cycle. By also destroying the next generation of flea eggs and larvae, Frontline Gold gives you the power to help prevent a flea infestation on your pet. Frontline products are highly recommended by veterinarians for flea and tick control for dogs.

Key Benefits
  • Provides fast-acting, long-lasting treatment and control from the makers of Frontline Plus.
  • Kills adult fleas, ticks, chewing lice, mites, and flea eggs and larvae that may transmit Lyme disease.
  • Safe for use on dogs and puppies 8 weeks or older between 23-44 pounds.
  • Kills flea eggs and larvae to stop existing infestations and prevent the establishment of new infestations.
  • Easy to apply and waterproof 24 hours after application.

Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

Recommended Dosage

1 applicator

*Remove one applicator tube from the package and hold in an upright position pointed away from your face. *Twist dispensing tip clockwise about 1/2 turn while pushing down to break the tube's seal. Do not remove the dispensing tip. Position the dispending tip on the dog's back between the shoulder blades. *Use the dispensing tip of the tube to part the dog's hair so that the product will be applied at skin level. *Begin squeezing out the contents of the tube to form a stripe as you move from the shoulder blades along the dog's back to the base of the tail. *Repeat every month.

Where do these new fleas come from?

Numerous hosts (including feral cats, opossums, raccoons, and other wildlife species) leave behind flea eggs wherever they go, including your yard. These outdoor flea infestations are often the primary source of the fleas that your pets pick up. Outdoors, developing flea stages can be found in areas protected from sunlight, so some of their favorite places include:

  • Sheds
  • Garages
  • Under porches or decks

How long will a flea infestation in the home last?

Flea eggs, larvae, and pupae in the environment continue to develop and emerge as new fleas (even after your pet has been treated with a flea control product). It can take weeks to months for this already established infestation to be controlled.

What else can I do to reduce the flea population in my home?

Regular use of an appropriate Frontline Gold brand product on your pet may reduce flea infestations in the home. For best results, use Frontline Gold brand products as part of a comprehensive flea treatment plan, which includes coordinated treatment of the home, yard and pet. Vacuum floors, carpets and furniture – especially in areas where an infested pet has spent a lot of time, because that is often where many flea eggs will be found. Wash pet bedding and other fabrics in hot water.

Why do I still see fleas on my pet after applying Frontline Gold?

There are two main reasons:

  • Fleas can jump onto your pet at any time (see where do new fleas come from), and these are not killed instantly.
  • Frontline Gold brand products are designed to kill any new fleas quickly and prevent their ability to reproduce. Frontline Gold kills fleas by overstimulating the flea nervous system, and hyperexcited fleas may move to the top of the haircoat before they die. So seeing fleas on top of the haircoat after applying Frontline Gold can be an indication that the product is working.

How does Frontline Gold for Dogs and Frontline Gold for Cats work?

After being applied, Frontline Gold for Dogs and Frontline Gold for Cats spreads all over the treated animal’s body and is stored in the sebaceous glands under the surface of the skin. From these glands, it is continually wicked through the hair follicles onto the skin and haircoat for a month or more.

Should I apply Frontline Gold for Dogs to ALL the dogs and Frontline Gold for Cats to ALL the cats in my household, even if they are indoor-only?

Absolutely. If you don’t treat every dog and cat, the untreated pets can continue to harbor fleas that will lay eggs, preventing the infestation from being cleared. Even if the dog or cat never goes outdoors, people may bring fleas into the home.

How often should I apply Frontline Gold brand products to my pets?

For continuous protection, apply an appropriate Frontline Gold brand product every 30 days as directed. Consistency is key.

Can I bathe my pet while using Frontline Gold?

Yes. Frontline Gold brand products remain effective for 30 days, even if your pet swims or is bathed. You may bathe your pet 48 hours after application. ONLY use a shampoo formulated for your pet and recommended by your veterinarian.

    Easy application. Lasts a month.

    By on

    We use Frontline on our three show dogs. It is easy to apply and lasts three months. Our dogs weigh about 40 lbs., so we buy the medium size.

    I thought the gold would be better but i have had to use it twice in less then two months on my puppy. It does not seem to even stunt the fleas or prevent.

    Buy A Different Product

    By on

    I ordered this Frontline Gold for the first time and tried to put it on my dog today. This is the worst dispensing tube I have ever seen. The seal is very difficult to break and does not break well. It is really hard to get the product out of the tube and on to the dog. I got it on me and the tube itself and have very little confidence that I got enough of it on my dog to do its job. My other dog is extremely difficult to medicate, and I do not think there is any way I can get this product on to him since it is so hard to dispense. My advice? Buy a different product.

    BEWARE! frontline products are trash -- total waste of money.

    By on

    i had always used advantix for over 20 years in maryland, and recently adopted an older dog that had always been on frontline so i decided to stay the course. 2 weeks after he got the spot he was COVERED in fleas. its taken a month of flea baths, grooming, and now switched back to advantix to clean him and my house.

    This flea medicine sucks

    By on

    I read a bunch of reviews so I saw a lot of positive reviews saying how much better frontline was. Last year I purchased advantage flea medicine and it lasted for 3 weeks. Frontline is the worst, it lasts 2 weeks maybe. I spent the extra money hoping it would last a little longer than advantage and being on a fixed income that's a big deal. I bombed my house, sprayed my lawn and still my dog is covered in fleas. He's suffering and I don't have another $50 to make this better. DONT buy frontline!!

    Empty bottle

    By on

    One of the bottles in this shipment which i just opened recently was EMPTY!!! First time that has ever happened to me. The tube itself was completely sealed so it did not leak. Weird. But I lost a whole application.

    Hopefully Optimistic

    By on

    I’ve always use Frontline Plus. I bought the Frontline Gold to have when the next application is due. I haven’t used the Gold yet but I am optimistic that it will be even better than Frontline Plus since it’s more expensive.

    Not for my girls!

    By on

    This year, Frontline has been useless on my dogs. Normally, I would be shouting their praises, but the fleas in this are seem to be resistant. I have used different Frontline products for decades and not had problems, until we moved into this house. The yard seems to be solid fleas, even with treatments and Frontline is not working at all! My older dog is so allergic to the fleas, she is not resting well.

    Not great but not terrible either

    By on

    Most of the fleas are gone from my dog but they are still scratching quite a bit after two weeks. I bathed them both and they had a lot of live fleas still on them. Not as expensive as others but not as effective either. At least not in SC.
