10 Reviews: Best Flea Killer for Dogs (Apr 2024)

Frontline Plus is recommended for puppies and kittens 8 weeks of age and older who want the most comprehensive flea and tick control possible. Frontline Plus not only kills up to 100% of adult fleas on your pet in 24 hours, but it also includes a unique chemical that destroys flea eggs and larvae, preventing all stages of fleas from forming and irritating your pet and family. Frontline Plus efficiently stops the formation of new fleas, thereby breaking the flea life cycle. Frontline Plus also kills all stages of four main ticks, including the Lyme disease-carrying tick.

Advantage Multi is a topical spot-on flea preventative that comprises the active chemicals imidacloprid and moxidectin to kill adult fleas before they can lay eggs, preventing flea infestations. It also protects against heartworm, mange mites, and other parasites in the intestine. This product is very easy to apply. Simply apply every 30 days to the dog’s skin between the shoulder blades at the base of the neck. Within hours, the liquid drug is absorbed and dried.

One of the few products of its type that can use on puppies. It was easy to apply. And so noticeable lingering smell!

Because it kills ticks and fleas, regulates flea infestations, and destroys chewing lice all in one simple application, Frontline Plus is a popular nonprescription suggestion. Each dosage of Frontline Plus may last up to three months when administered just for flea control. If ticks or biting lice are a problem, use it once a month. Frontline Plus kills parasites on touch, so they don’t have to bite your dog to work. Fipronil and S-methoprene, the active chemicals, work together to kill parasites and terminate the flea life cycle. Adult fleas and ticks are killed by fipronil. S-methoprene prevents the development of flea eggs, larvae, and pupae.

I will not use anything else on my dogs. if applied correctly you have zero bugs on your dogs. You really have to part the hairs and apply it to the actual skin of the dog for it to work (I use two small tooth combs to part dogs hair). I bath dogs and then wait 3 to 4 days for their skin oil to return and then apply. You can't go wrong!

Capstar for Dogs is the only flea control treatment available without a prescription that is safe for pups as young as four weeks old and weighing at least two pounds. Capstar’s main component, nitenpyram, starts working in 30 minutes and kills over 90% of adult fleas on dogs in as little as four hours. Capstar’s flea protection is only good for 24 hours, but it’s safe to use it every day if required. This is beneficial for small pups who may not be mature enough to utilize a long-term protection oral or topical treatment.

This is amazing this is by far the best flea medicine I’ve ever purchased, it works amazingly fast, in like one hour all the visible fleas were dead I just couldn’t believe it I would give this product 10/5 if I could

I have been using these for years and they work amazing!! I have bought off brands trying to save money and it wasn't worth it they were a waste these don't irritate any of my dogs and they work!!! I have never found a flea or tick on them with this on or a bite of any kind to be honest. I love how they're water proof and don't smell. I will never go with a different one ever again

With this dog shampoo from Adams, you can kill fleas and ticks while still keeping your dog clean. It’s soft on both you and your dog’s skin, including aloe, lanolin, coconut extract, and oatmeal in the formula—and it smells great, too. Because a little goes a long way, the bottle should last quite a while. The shampoo includes an insect growth regulator (IGR) that, according to the makers, may kill fleas and prevent them from developing for up to 28 days.

Worked great. My poor dog must have been super infested or the other stuf we used previous just wasnt good enough. I would definitely buy this again.

Lemongrass and cedarwood oil, which are naturally repellent to a range of insect pests, are the major active components of Wondercide spray. This spray may be used on your dog directly or as a room spray to eradicate fleas and ticks on your furniture and carpet. It’s available in a variety of fragrances. When spraying your dog, make sure you don’t forget to spray their armpits and in between their toes, two common parasite hiding locations.

I have all of a sudden been experiencing severe allergic reactions to gnat and mosquito bites and someone suggested this. The fact that I can share it with my dog as a flea and tick repellent?? WIN WIN!! The scent is not offensively strong at all and it seems to last. Get the set of 2 bottles so you can keep 1 in car and 1 at home. A little goes a long way too!!

A small dog does not need the same amount of flea and ticks preventive medicine as a large dog, and the same is true for topicals. Sentry’s product is designed for dogs weighing 4 to 22 pounds. It kills fleas, flea eggs, flea larvae, ticks, and chewing lice on contact and may be applied to your dog’s back every 30 days. To open the tubes, you’ll need scissors. Your dog won’t be able to lick it off after it dries, and it’s okay for him to get wet after a few days.

I have been using this product for a few years now. It works on both my dogs -- 16 lb terrier mutt mix and a 90 lb. lab. no fleas or attached ticks (knock wood).

Because not all flea and tick medications are safe for puppies, you should consult your veterinarian before buying one. K9 Advantix may be used on puppies as early as seven weeks old, and the small dog type is designed for canines weighing four to ten pounds. To combat pests at various phases of their lifecycle, the therapy combines three separate ingredients: a flea adulticide, a repellent, and an insect growth regulator. The topical lasts 30 days and kills fleas, ticks, and mosquitoes on contact, so fleas, ticks, and mosquitoes don’t have to touch your dog to be killed. It kills fleas within 12 hours of treatment.

Just took a camping trip with my dog and we walked lots of backwoods trails...before we realized that there were more deer than usual (in Florida) and with them deer ticks! Every tick, which I later found on my dog, was near death or dead. I had applied the product 5 days before we went camping. It worked beautifully! Great Seller, price and product.
