Experienced and professional animal trainer provide their insights in answering this question :
A. Oral products, such as NexGard, are similarly effective against fleas and ticks in comparison to topically applied products. However, keep in mind that NexGard has only been proven safe in dogs, not in cats. The active ingredient in NexGard is afoxolaner, which kills fleas by over-stimulating their nervous system.

Many pet owners prefer this product because they do not have to worry about administer a liquid product on their pet’s fur.

How to Identify Common Pet Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced pet care professionals :

Oral flea and tick preventatives can be more effective than traditional topically administered medications. Two of the biggest benefits of oral flea and tick medications are that they are FDA approved and safe for pets to ingest.
A ninety-day study published in Veterinary Parasitology (the top reference publication for veterinarians) involving 128 dogs from five states, and found that topicals were 88.4% effective, while oral treatments were 99.9% effective.
Pills with the active ingredients lufenuron, nitenpyram, or spinosad can be a better option, for both animals and humans, than treatments that leave residue on fur that might get on hands or furniture.
The most common adverse side effects of oral flea-control medication are stomach upset and vomiting. The very fact that a dog can vomit up the medication – and the possibility that he might do so without you being aware of this – is a fairly significant disadvantage, too.
Best OTC topical preventive: Frontline Plus

Among the best flea treatments for dogs, Frontline Plus is our top nonprescription recommendation because it kills ticks and fleas, controls flea infestations, and kills chewing lice, all with one easy application.

The Pros of Flea Pills

Flea pills are very effective in killing adult fleas, and many would say they`re the most effective treatment option for this purpose – as long as your dog ingests the tablet.

Studies looking at the efficacy and speed of tick kill for one of the oral tick products show that within two weeks of administering the monthly medication, less than 1/3 of ticks were killed within the 12 hour mark which means that Lyme, Anaplasma and Ehrlichia have already had a chance to infect your dog.
After ingestion, some oral flea, like Trifexis, preventatives begin to kill fleas in at little as 30 minutes and kill 100% of fleas within 24 hours. Fluralaner, afoxolaner, spinosad, milbemycin oxime, praziquantel, and sarolaner are among the many common ingredients found in oral flea and tick preventatives.
1. Best Overall: Frontline Plus Topical Treatment.
The answer is yes, flea and tick preventatives need to be applied year-round in order to keep your pets safe. Read on to learn more about how fleas and ticks operate, the dangers they can harbor, and how best to protect your dogs and cats.
You`re Applying the Flea Treatment Incorrectly

Incorrectly applying topical flea prevention is the most common cause for why it`s not working. Topical medication should be applied directly to the skin, not to your pet`s fur. You must part their hair so you can apply it to the skin.

And many vets recommend alternating the doses between topical and oral medications. Again, these are only in extreme cases. So it can be safe to use the two medications together, but it`s usually not necessary. Always talk to your vet before using more than one flea medication.
Thoroughly bathe pets with soap and water, then comb them with a flea comb. Pay careful attention to face and neck regions, and the area in front of the tail. Soap will act as a gentle insecticide to kill adult fleas. Talk to your veterinarian about choosing the right flea control product for your pet.
Prescription flea and tick medications use different ingredients that can be more effective. However, they can have a smaller margin of error when it comes to safe, effective use, so you can only buy them with your veterinarian`s guidance.
Advantages. Collars are a good choice for those who don`t want to be on a monthly schedule of applying a topical between the shoulder blades or giving tablets by mouth, which some dogs hate. They last up to 6 to 8 months at a time.
The most common reason is that the fleas are being killed and the dog is no longer being bitten by them. This can cause the dog to feel itchy and uncomfortable, which may lead to restlessness. Additionally, the chemicals in some flea treatments can be irritating to dogs, leading to discomfort and restlessness.
With regard to the number of reported deaths, the largest number was for sarolaner+mox idectin+pyrantel+pamoate (Simparica Trio®) at 6,717 (approved in 2020), followed closely by spinosad+milbemycin+oxime(TriFe xis®) with 6,662 (approved in 2011) and ivermectin+pyrantel+pa moate+praziquantel (Iverhart Max®, approved in …
You may find that the oral delivery method creates less of a mess than the topical route, while also eliminating concerns over skin reactions to the active ingredients. But oral medications may also cost more than topical treatments, and prescriptions will need to be refilled regularly to maintain constant protection.
Topical preventions have been shown to clear current flea burdens on dogs within 12–48 hours, and oral preventions often work within the first two to four hours. When it comes to ticks, both oral and topical options should cause tick death in 24–48 hours.
Fleas are typically killed by one application of a topical flea treatment that should last for 4-6 weeks or even longer, depending on the product used.
Yes, Nexgard is an incredibly safe and effective prevention for fleas, ticks, and mites. However, because Nexgard is ingested and absorbed into the bloodstream, rather than applied to and spread by the oils of the skin, the few reactions that do occur can seem more dramatic.
Disadvantages: Pet flea sprays can be messy and time-consuming because it needs to be applied to the dog`s entire body for full protection and some pet sprays need to be re-applied very frequently.
Yes. Though many species of ticks and fleas are slowed down or dormant during the winter, certain areas of the United States are not cold enough to truly kill these parasites and stop their activity. Because ticks and fleas can carry diseases that could harm your dog, it`s best to keep them protected all year long.
McLean said tick repellents for pets are more like insecticides. They contain a chemical called permethrin. And because it`s designed to kill pests rather than repel them, you don`t want it on you. “Even though this insecticide isn`t necessarily bad for mammals, you want to avoid putting it on your skin,” McLean said.

Relevant Questions and Answers :

the most relevant questions and answers related to your specific issue

Q. Which flea and tick drops are the best and why?
ANSWER : A. Your question is a good one, and unfortunately the answers are going to differ based on who you ask. Many vets are seeing resistance to Frontline, which has been the go-to product for many of us for many years. It contains the active ingredient Fipronil, which is very safe and typically extremely effective. I use it on my dogs and never see fleas or ticks. However other vets will tell you in their areas, for whatever reason, they are seeing fleas and ticks on dogs and cats on which this product was used.

Another reason opinions differ is that some people like to give an oral product, and some like to put a topical product directly on the skin. That’s a matter of personal preference mostly. Bravecto, as mentioned below, is one of those products. Most people find it safe and effective. It uses a different process that Frontline to kill fleas and ticks.

In general the products you buy over-the-counter are likely going to be less expensive and less effective than what you get from a vet. I think the reason is that the more expensive products contain newer insecticides, and likely less resistance to these products has built up in the flea and tick population but also they are maybe less “proven”, so it’s important for a vet to be involved in the use of the product in order to ensure that there won’t be a negative reaction to using it.

If I lived in an area where there was Lyme disease (in the US that’s the northeast and upper midwest) I’d most definitely add a tick collar to my standard oral or topical flea and tick prevention. AND I’d search both of my dogs everyday for ticks. It’s because nothing you buy will be 100% effective, and Lyme disease can be a very serious problem.

If you want to talk further and talk more specifically about where you live and what products you’re considering, I’d be happy to do a consult with you. Nobody here is paid to recommend products, but we do develop preferences based on what we use on our own pets and in our practices.

Q. My cat is excessively scrstching herself., to the point she has sores. She is strictly an indoor cat. Did have flees been treated for 2 months
ANSWER : A. For every flea you see on your pet, there are 100 more in the environment. Get your pet on a good topical or oral flea control through your vet. In flea control, you get what you pay for. Consider asking your vet for a dose of Capstar. It helps get the problem under control by killing the fleas on the pet starting in five minutes but only lasts for 24 hours.

You need to treat your home environment. If you use a pest control service, tell them you are having a flea problem and they can adjust their treatment. Use a premise spray that also contains an IGR, insect growth regulator. This keeps eggs and larvae from maturing into adults and helps break the life cycle. Also, vacuum EVERY DAY, throwing out the bag or emptying the canister every time into an outside receptacle and spraying the contents with insecticide to kill the fleas you’ve vacuumed up.

Treat your yard too, since fleas are opportunistic and will hop a ride into your home on your pant leg without you knowing it. Concentrate on areas under bushes, in the shade. Fleas are less likely to be located in open sunny areas where it gets hot.

If chemicals are a problem, you can use borax. Sprinkle it into rugs, into corners and under furniture, use a broom to work it into the fibers and let it sit for hours, days even. It won’t hurt you or your pet to have it present. Then vacuum it up, reapply as needed. Food grade diatomaceous earth can be gotten from a health food store and worked into the rugs and corners in the same way as borax. These treatments aren’t as fast and effective as chemical insecticides but they can help.

You might want to consider boarding your pet for the day at your vet, to give you the opportunity to flea bomb your house without having to worry about your pet being exposed. They can bathe your pet and give a dose of Capstar while you treat your home.

Be patient, you may have to repeat these steps multiple times 10-14 days apart to help break the flea life cycle.

Skin problems can have a variety of causes, sometimes more than one. It is important to have the problem checked by your vet to determine if there is a medical cause for your pet’s skin issues and treat accordingly.

In pets of all ages, fleas, food allergies and exposure to chemical irritants such as cleaners and soaps can be a cause. Any one of these may not be enough to trigger the breakouts, depending on how sensitive your pet is, but a combination can be enough to start the itch-scratch cycle. Finding out the cause and eliminating it is the best course of action. With flea allergies, if your pet is sensitive enough, a single bite can cause them to break out scratch enough to tear their skin.

Check for fleas with a flea comb. Look for fleas and/or tiny black granules, like coarse black pepper. This is flea feces, consisting of digested, dried blood. You may find tiny white particles, like salt, which are the flea eggs. Applying a good topical monthly flea treatment and aggressively treating your house and yard will help break the flea life cycle.

If you use plastic bowls, this is a possible cause for hair loss, though this tends to be on the chin, where their skin touches the bowl while they eat. If you suspect this to be the culprit, try changing the bowls to glass, metal or ceramic.

Food allergies are often caused by sensitivity to a protein in the food. Hill’s Science Diet offers some non-prescription options for sensitive skin as well as prescription hypoallergenic foods for more severe cases. Royal Canin carries limited protein diets that may also offer some relief. Your vet can recommend a specific diet that will help.

If there is no relief or not enough, consider getting your pet checked by a veterinary dermatologist and having allergy testing done.

Q. Are oral flea and tick preventative products less effective than topical products?
ANSWER : A. Oral products, such as NexGard, are similarly effective against fleas and ticks in comparison to topically applied products. However, keep in mind that NexGard has only been proven safe in dogs, not in cats. The active ingredient in NexGard is afoxolaner, which kills fleas by over-stimulating their nervous system.

Many pet owners prefer this product because they do not have to worry about administer a liquid product on their pet’s fur.

Q. Do natural flea control products work?
ANSWER : A. Although many natural flea control products don’t have to go through EPA-mandated tests, because they aren’t classified as pesticides, this doesn’t mean they don’t work.

There are several natural flea control products that are safe for your home and your pets: repellants, sprays, squeeze-ons, shampoos, flea tags and powder. Also garlic and B-vitamins seem to make blood less attractive to fleas, so many guardians supplement with garlic and brewers yeast during flea season. However, sensitive animals can develop an allergy to brewer’s yeast, so I suggest you monitor your pet to guard against worsening itchiness.

Many people use the natural approach to flea control effectively and, although it is not always as easy as using chemicals, it’s generally safer for your pet and your family. Regarding chemicals, the US Environmental Protection Agency recently completed an in-depth investigation due to the hundreds of reports of illness and death in pets and serious adverse effects were reported for every product EPA assessed. EPA is in the process of increasing restrictions on their use. You can read more information about this report here: http://www2.epa.gov/pets/epa-evaluation-pet-spot-products-analysis-and-plans-reducing-harmful-effects

Besides, most chemicals, including bombs and sprays, kill only adult fleas or adults and larvae. That leaves thousands of tough little eggs and cocoons just waiting for the proper conditions, when they’ll renew their assault once more.

That said, you must keep in mind that a product labeled as “natural” or “organic” could still be not suitable, or even harmful, for your pet. Therefore, I recommend consulting with your veterinarian or trying to find a holistic veterinarian who can offer you guidance about natural flea control products.

Q. Our cat developed a flea allergy in the form of red sores above the eyes Our vet gave him an antibiotic shot and a flea collar but they remain.
ANSWER : A. I’m so sorry to hear! Flea allergies are tough to deal with! Unfortunately when a pet has an allergy to fleas, the problem lies in the flea bite. The actual allergy lies in the flea saliva, so what we really need to prevent is the flea biting our pet! I would recommend a product that can kill the flea before they even have a chance to bite your pet! A couple of really great products on the market right now are Frontline Plus and Revolution. Both are liquid topical products that you place on the skin of your pet once a month. They work by using the skins oils to spread themselves around the body and rest in the hair follicles. Each has a slightly different mechanism of use, but they both work to kill the flea before it actually has a chance to do harm to your cat. Flea collars simply are not as effective. I would also recommend treating your home environment, such as the area where the cat sleeps and the carpets inside your home. Flea eggs and larva can live for a very long time in these environments and unless we treat all of these areas, the problem will remain. I hope this was helpful! Good luck and I hope your kitty feels better!

Q. My 13 year old male cat is acting lethargic & doesn’t seem to be feeling well. I don’t know what’s wrong except that he has fleas. Can too many fleas
ANSWER : A. Excessive fleas can cause anemia in cats, left untreated, this can be life-threatening. I recommend getting your cat seen by your vet right away for his illness. For every flea you see on your pet, there are 100 more in the environment. Get your pet on a good topical or oral flea control through your vet. In flea control, you get what you pay for. Consider asking your vet for a dose of Capstar. It helps get the problem under control by killing the fleas on the pet starting in five minutes but only lasts for 24 hours.

Q. My dog has fleas and ticks. I’ve kept her area clean and bathed her. If I took her to the grooming salon, would they be able to help her issue?
ANSWER : A. To be honest with you, the groomer will do just about the same thing you have done for her at home, which is bathe your pet to rid all the fleas and flea eggs off of her that are currently on her.
However, the problem comes with re-infestation. Everytime your pet goes outside to potty and comes back inside, she has a potential to carry fleas in with her, even if she is only out there for a few minutes a day. In fact 40% of indoor pets has fleas, so we know that they can be extremely opportunistic.
The best and only way to protect your pet from fleas and ticks is by using a flea/tick preventative. Here are my top picks!:
1) Nexgard
2) Seresto collar
3) Advantix topical

These products are going to get the job done. Also you have to treat your home with a flea fogger (can be purchased at Home depot or Lowes) and wash all your pets bedding to help rid the flea eggs in the environment. This is key to overall flea ridding and flea control.
