Best Flea and Tick Treatment and Prevention for Dogs in 2021

Every year, your dog becomes susceptible to ticks and fleas which can easily grow and multiply if left unattended. Worse is, they can even cause your dog to develop some health issues if not taken care of. This gets even worse during early Spring.

Fortunately, you can save your dog from a flea or tick infestation by using the best treatment for dogs. In this article, we’ll tackle some products which are considered to be among the best flea treatment for dogs. We’ll also guide you through the buying process so you can find out which product suits your furry friends.

Why My Dog Needs Flea Treatment?

As warmer weather begins, fleas and ticks will start emerging in massive numbers, making them quite annoying to your pets. If left untreated, a flea infestation can cause your dog to suffer from serious health conditions and may even make your house uninhabitable, not to mention it can make you and your family sick as well. It is for this reason why your dog needs a flea treatment.

Aside from that, preventing them from multiplying is way cheaper than controlling them once an infestation occurs. Flea treatments which are available on the market have insect growth regulators which are capable of preventing eggs and larvae from maturing.

However, you have to keep in mind that fleas can also be active during the winter season, although they’re less active than during the spring and summer seasons. It is, therefore, advised to use flea treatment all-year round, even if your dog spends most of his time inside your house.

In some cases, you might be the one carrying unwanted pests into your house from pests who cling into your shoes or clothing. But before you even give your dog a flea treatment, you should first consult your veterinarian so he can recommend a safe and effective year-round protection.

How to Choose the Best Flea and Tick Prevention for Dogs

Due to the number of products on the market, choosing the right one for your pet can be quite overwhelming. Therefore, we’ve listed the most important factors you should consider whenever you go shopping for one.

Without further ado, here are the factors you have to take into account:

The Extent of the Infestation

Before going for a certain product, you should first consider the severity of the infestation. Since fleas and ticks can multiply really fast, it would mean that a few ones on your pet could mean over a hundred in a day or two. Aside from that, fleas are capable of jumping over 100 times its size, which simply means they can move pretty quickly.

Therefore, if the infestation has already reached your towels, furniture, rugs, carpet, and other stuff, you’ll have to be more vigilant in treating your dog and your house at once. You’ll want to check every nook and cranny, especially in your bed and couch. Depending on the extent of the infestation, you might have to shave the affected areas in your dog.

Meanwhile, if there’s only a few fleas or ticks on your dog, you can just give him a flea bath or perhaps a dip at the vet. However, if they’ve taken over your house, you’ll have to consider treating both your dog and house at the same time.


You might not know it, but there are a hundred different species of fleas and ticks around the world. The brown dog tick and the American dog tick are just a few of them. To find the right treatment, you’ll have to consult your veterinarian so you can verify the particular species in your residence and find the most effective treatment for the infestation.

Ideally, you want to look for the best flea treatment for dogs is labeled “broad spectrum” so you can deal with several species of fleas and ticks in one go. Aside from that, it’s very easy to use as well.

Your Pet’s Lifestyle

Another important factor you should consider is the lifestyle of your dog. For example, your dog might not be fond of preventative treatments and may not stay still during the treatment. For this, you’ll have to consider buying a flea and tick collar.

However, if your dog has an active lifestyle, then you have to consider a treatment that can last for a long time and won’t be visible on your pet. For that, you’ll have to buy either oral tablets, sprays, powders, and dips. You can also find a dog shampoo that is specially formulated to combat and prevent an infestation. Technically speaking, there’s no right or wrong choice when it comes to choosing the best treatment for dogs. Just choose what you think works well for your situation.


If you also have a pet cat in your household, you’ll want to consider a treatment that applies to both dogs and cats. In some cases, they can take the same treatment, but you’ll have to consult your veterinarian first.

Therefore, before you even try to apply the same treatment you give your dogs on your cat, you’ll have to make a consultation first. This is because some flea and tick medications come with a special formulation which can be effective for dogs but contains ingredients which could be harmful, or even deadly, for cats.

That said, you should pay close attention to the label of a product and use it only as directed. For this, asking your veterinarian can really help.

Dog Size

Additionally, you’ll have to consider the size of your dog because certain flea treatments are used only for dogs of a certain size. Therefore, if you have a small-breed dog, you don’t want to apply a medication that’s designed for large breeds. Also, using a treatment that’s specifically designed for large-breed dogs on your small-breed pet, and vice versa, may result in some side effects.


Flea and tick treatments actually come in a variety of types. That said, here are the different types of flea and tick treatments you can find on the market:

Topical treatments

Topical treatments, likewise known as spot-on treatments, are directly applied to your dog’s to kill both fleas and ticks as well as eliminate any eggs and larvae left behind by the fleas. The best thing about this type of treatment is that it’s very easy to apply and is really effective as well.

Although you’ll have to prevent your pet from getting wet after an application, a lot of topical treatments available are actually waterproof, making them the ideal choice if you plan to bathe your pet during the treatment.

Dips and shampoos

A dip is a treatment which is diluted with water then applied to your dog in the same way that you would apply a shampoo. This type of treatment can last for up to 35 days. Shampoos, on the other hand, may last between 5 to 14 days depending on the product.

Shampoos are only designed for short-term use as the effects won’t last for long. However, they’re really effective for killing fleas and ticks on contact. Meanwhile, dips are concentrated solutions that can last for a longer time compared to shampoos. That said, you only have to use them right after consulting your vet.


Collars are worn around the neck of your dog and will offer treatment and prevention for a few months. Generally, they work by either releasing a chemical that can kill or repel ticks and fleas around the neck area or by releasing ingredients which are then absorbed and spread throughout your dog’s skin.

Most collars contain a concentrated chemical which is really effective for killing fleas and ticks. However, while they’re quite affordable, the strong smell they give off can be irritating for your pet. They also have some associated risks when touched by humans, particularly children.


A flea and tick powder is considered the dry version of topical treatments. You simply have to sprinkle it over your dog’s body then rub it into his hair. However, you’ll have to be careful not to sprinkle it near your dog’s eyes and mouths as it can lead to certain side effects such as vomiting, drooling, diarrhea, and even depression.

Oral treatments

Oral medications are becoming a popular option for eradicating fleas and ticks on dogs mainly because they are designed to offer a quick flea and tick relief. Some oral treatments are capable of killing fleas and ticks within just 30 minutes after being taken by dogs.

However, oral treatments don’t have the ability to prevent fleas and ticks from sticking on your dog. Therefore, you’ll have to wait for them to actually attach or bite your dogs before they can get killed. Also, they have a risk of upsetting your dog’s stomach.

That said, oral treatments offer a really quick way of treating fleas and ticks on your dogs. Aside from that, they can also help prevent heartworm disease in your pets. However, if you want a preventative measure, you’re better off using a topical treatment instead.

Flea combs

If you’re lucky to notice the pests even before they grow into an infestation, then a flea comb is more than enough to take care of them. What it does is make sure that it removes any and all fleas that are hiding in your dog. Ideally, you have to add a teaspoon of dishwashing liquid or apple cider vinegar in the comb so you can immobilize and even kill the fleas when combing.

Q: How to lower the risk of my dog getting fleas?

A: To keep your house and dog free from any fleas and ticks, here are the different ways you can follow:

  1. Start by cleaning your yard. Your very first line of defense is to keep fleas and ticks from setting up camp inside your property. To do that, you’ll have to start by cleaning your yard. That means you have to mow your lawn, trim any shrubs, and seal off the openings to your garage, crawl spaces, or any space where wild animals might stay. As much as possible, don’t let raccoons, feral cats, and opossums get into your yards considering that they’ll most likely bring fleas with them.
  2. The next step is to keep your house clean. This includes vacuuming your carpets and washing your pet’s crate, beddings, and toys. This will likely kill the larvae and eggs which might have nested in them.
  3. After keeping your house clean, the next thing to do is to eliminate any existing fleas and ticks on your pet. You can achieve this by using a flea and tick prevention designed for dogs. The types of treatment you can choose from are stated above. You should also bathe your dog regularly and apply dog colognes afterward.
  4. Lastly, you have to prevent a reinfestation from happening. There are a number of flea medications which are also effective in preventing a future infestation from happening. However, make sure you only choose the products which are intended for your dog’s age and size.

Q: How often should I use the flea treatment

A: Bites from fleas and ticks can be really annoying for your dog, not to mention they can make him sick. However, how often you should use a treatment to get rid of them will depend on the type of product you use. Here’s a useful guide you might want to look into:

  • For flea collars, they can last for up to seven months.
  • A flea spray is an effective solution that will kill and repel pests for up to seven days. However, it will prevent the eggs from hatching for up to 30 days.
  • A flea shampoo can kill any existing fleas and ticks while preventing reinfestation for up to two weeks.
  • A flea drop can prevent reinfestation for up to 30 days.
  • An oral pill can provide a quick relief but won’t prevent a reinfestation.

Q: How long does flea treatment take to work?

A: On average, a flea treatment can take anywhere between a few hours to a day to take effect. Most of the products we’ve included on this list can work within 12 hours after applying.

Q: When can puppies get flea treatment?

A: You can apply a flea treatment to puppies under 12 weeks old. However, you need to make sure you consult your vet first. Meanwhile, a topical treatment can be administered for as early as 6-8 weeks old.


Managing and preventing a flea and tick infestation from coming back will require a number of approaches. Choosing the best flea and tick prevention for dogs is just one of the many approaches you have to follow. Hopefully, you can find everything you need when it comes to the best treatment for your dogs.
