Before you apply a topical flea treatment to your dog, it would be good to ascertain how clean your dog is.

Does your dog look like it has been living out in the wild for years?

Is its fur caked with mud and debris?

Bathing ensures that your dog’s skin and coat are clean.

Removing dirt and debris can potentially improve the effectiveness of the flea treatment, as there are no barriers between the medication and the dog’s skin.

How Bad Is Your Dog’s Flea Infestation?

Ascertaining the severity of your dog’s flea infestation can also help you come to a decision.

Does your dog’s coat resemble a flea vacation retreat?

Or do you just notice a few fleas on your dog?

If your dog is having a bad flea episode, it might be a good idea to give it a flea bath with flea shampoo first to get rid of as many adult fleas as possible.

This can give your dog some immediate relief from itching and discomfort.

After showering your dog, use a flea comb to further remove more fleas.

Why You Should Not Bathe Your Dog Before Flea Treatment?

“This natural oil is critical in helping to spread the topical flea medication across your dog’s body.”

While there’s some debate about bathing your dog before flea treatment, one aspect seems consistent.

The role of your dog’s natural skin oils.

Your dog’s skin secretes sebum which is an oil that helps to keep its skin soft, makes its fur waterproof and also has antibacterial properties.

Protip: Avoid taking your dog for a walk right after a bath during cold or wet conditions. It takes a few days for your dog’s fur to become waterproof again.

This natural oil is critical in helping to spread the topical flea medication across your dog’s body.

When you bathe or shower your dog, the shampoo can strip these oils away, leaving the skin less conducive to medication distribution and absorption.

Topical flea treatments work better on a “dirty” dog. Wait a few days after washing to apply.

This doesn’t quite apply if you are giving your dog an oral treatment like Nexgard.

When giving your dog Nexgard, feed the right amount according to your dog’s weight. You don’t want to overdose your pup on Nexgard.

If your flea-infested dog is badly in need of a bath, then do it soon and apply the flea treatment only after 24 hours.

Do not apply the treatment immediately on your dog after a bath as that would reduce its effectiveness drastically.

The solution gets pooled up at the neck because it can’t travel down the natural oils in the dog’s coat.

If you can wait for 48 hours, that would be even better.

That would allow your dog’s natural oil to sufficiently build back up and help to better distribute the topical solution.

You can bathe your dog after applying flea treatment but only after waiting for at least 48 hours.

This waiting period allows the solution to be fully absorbed into the skin and start doing its job effectively.

It will be even better if you can give it 72 hours before showering your dog.

Bathing your dog too soon after application could wash away the medication and reduce its effectiveness.

Why A Flea Infestation On Your Dog Is Dangerous?

As mentioned earlier, fleas on your dog in more than just a nuisance like a mozzie bite.

A bad flea infestation can cause severe itchiness and lead to skin infections from persistent scratching.

Some dogs can even develop an allergic reaction to flea bites, causing nasty skin lesions and bleeding.

Here are other complications that can arise from a flea infestation.

Parasite Transmission

“These fleas can be carrying tapeworms in them which will then be transmitted to your dog and live in its digestive tract.”

Not only are these pesky blood suckers parasitic but they can also pass on parasites to your dog.

Fleas can give your dog tapeworms.

When your dog licks itself, it can accidentally ingest the fleas on its body.

These fleas can be carrying tapeworms in them which will then be transmitted to your dog and live in its digestive tract.

Tapeworms can cause a multitude of health issues for your dog as they feed on the nutrients that your dog eats.

Loss Of Too Much Blood

Fleas feed on your dog’s blood to stay alive.

And each female flea is capable of laying up to 50 eggs a day.

If you do the math, these can quickly lead to many of these parasites feeding on your dog’s blood as sustenance.

It might not matter for large adult dogs but for small dog breeds and puppies, this problem can lead to anemia which is a lack of red blood cells.

This can be life-threatening if not promptly addressed.

How Do I Prevent Fleas In My Dog?

Your dog’s health is paramount and managing fleas is a crucial aspect of that.

Truth be told, it won’t be possible to totally prevent your dog from getting fleas due to their lifestyle.

Our dogs love playing in fields and with other dogs where the chances of getting fleas are a lot higher as compared to an indoor cat.

Here are some ways that can help minimize the risk of getting fleas.

Watch Where Your Dog Goes

One practice that really helps to keep fleas away from my dog is to not let him venture into areas where they might live.

Fleas like to live in high grass and damp shady places.

Make sure to keep your dog away from these areas.

Regular Checks

Another effective way is to manually check your dog for fleas at least once a week.

It is a bonding time with my dog where he will just lie in front of me and I will check him.

Fleas like to set up camp at the base of the dog’s tail so make sure to check there too.

If your dog is dark in color, spotting fleas can be challenging.

Use a flea comb to brush your dog and see if there are any fleas or crusty red debris on it.

Regular Flea Treatment (Maybe)

Many dog owners are not fans of applying topical flea treatments on their dogs on a regular basis.

Even though the manufacturers have claimed that it is safe, there’s no telling the kind of long-term impact it can have on our dogs.

I don’t use flea control on my dog regularly unless he has signs of an infestation.

The only thing I will do is give him a flea bath or shower him with flea shampoo as a preventive measure.

But you can’t do it too often as these treatments can dry out your dog’s skin.


How Long After Flea Treatment Will Fleas Be Gone?

It usually takes about 24 to 48 hours for fleas to start dying off. The complete elimination of all fleas, including eggs and larvae can take several weeks depending on the severity of the infestation and the effectiveness of the treatment used.

How Does Flea Medicine Work?

When the fleas feed on your dog, they will also ingest the topical solution that is in your dog’s skin. The active ingredient targets the nervous system of the fleas and making them unable to feed on your pet.

Can You Use Flea Shampoo And Flea Medicine Together?

Using both flea shampoo and medication together is generally not advised. This is because using both simultaneously may lead to an overdose of active ingredients which could potentially be harmful to your pet.

Does Bathing A Dog Help With Fleas?

Bathing your dog can certainly help in the battle against fleas. A good bath with an anti-flea shampoo can remove some fleas currently on your dog’s body and soothe its irritated skin.
