This oral administered product works best and safe for puppies from 8 weeks of age and above, weighing 4 pounds and above.

It comes in an easy-to-use and odorless collar and effectively kills and repels fleas in and from your dogs.

This dual-action collar is water-resistant, and thus no matter your dog’s exposure to water (whether by swimming, bathing, or under rain), it remains effective.

If you’re looking for a holistic strategy rather than a preventive measure in battling dog fleas, you may want to check this product out – Capstar Fast-Acting Oral Flea Treatment for Dogs.

Each tablet contains a formulation of Nitenpyram, a very effective chemical substance for addressing flea infestation.

How To Tell If Your Dog Has Fleas

Fleas can cause serious harm to dogs, and depending on the stage of their growth, can be very small and somewhat invisible to the careless eye.

When not given adequate treatment, they can make your dog’s life so miserable and even lead to flea-related conditions.

Here are signs of being aware, so you address the situation before it becomes serious.

Sign 1: Itch/Scratch

Fleas are known for their release of saliva when they bite, which can be very irritating to your dogs. One of the ways it manifests is itching.

I used to think this was an old wife’s tale until I saw restlessness in my dog characterized by severe itching.

Sign 2: Hair Loss

One way you can tell that fleas have been up to something with your dog is by noticing hair loss on them. This hair loss is not a direct effect of the flea bite but a result of its irritation while attempting to get them off.

This is commonly observed in the dog’s hindquarters, such as on the neck, legs, back, or tail’s base.

Sign 3: Pale Gums

Fleas are known to be heavy drinkers of blood. Imagine having this parasite in large numbers and on your dog? The result is seriously drained blood.

As this happens, the supply of hemoglobin is affected, thereby leading to anemia signaled by the gum’s paleness. That could also lead to dizziness, weakness, and breathing problems.

Sign 4: Tapeworm-infested Feces

Fleas are sometimes carriers of the larvae of tapeworms.

A dog tends to ingest them (together with the fleas) when they resolve to biting and licking the parts of their body that itch in an attempt to find relief.

The tapeworm tends to shed off its parts into the waste in your dog’s intestine.

Sign 5: Flea Droppings and Eggs

A dog flea can lay eggs in its mature life stage, as much as 20 to 50 in one day.

Also, like any living organism, they produce waste that appears like tiny black dots. These eggs are usually white-colored and oval in shape, looking like granules of pepper and salt.

There’s always a tendency that these dropping and eggs will be found on the ground. (1)


 

Types Of Flea Treatments

Like I said earlier, there are many anti-flea treatments on the market. But, they are commonly placed under the following categories:

Oral/Pills

Oral medicines are probably the best dog treats for fleas options, in my own opinion. They come in the form of tablets and pills containing insecticides having nitenpyram or imidacloprid as a major ingredient.

As they are ingested, the ingredients make their way to the bloodstream and settle there, waiting for the next flea bite. When that happens, the fleas get to ingest the poison contained in the insecticide and die.

Pills generally last for an average of 24 hours, and as such, they need to be administered to your dogs every day until the infestation is completely handled.

Topical

Topical flea treatment generally refers to flea drops or spot treatments featuring insecticides such as pyriproxyfen or permethrin (or (s)-methoprene and fipronil), applied behind the neck of your dog, which then spreads to other areas of their skin’s surface.

As this happens, every flea bite is in danger of ingesting chemicals and dying. They don’t make it to the dog’s bloodstream but rather directly on the fleas.

Generally, topical medications will last for about 30 days, after which they will need to be reapplied. They are also an effective means of dealing with fleas.

Collar

This is another type of flea medicine that is effective and popular in keeping fleas at bay.

They are particularly effective at repelling fleas rather than when the infestation is existing.

Like the topical option, flea collars are designed to release chemicals on your dog’s neck, which then spreads to the surface of your dog’s skin.

This option is considered a problem as pets are likely to chew on other pet’s collar or their own when it slips out. When such happens, your pets stand a chance of poisoning.

Shampoos

Like other types of flea medicines, a flea shampoo contains poisonous ingredients such as pyrethrum but is to be used as shampoos.

When used to shampoo your dog’s skin, the poisonous ingredients stay on their coat. They, in turn, either kill any existing fleas or make your dog’s coat undesirable for them that they leave.

This type of medication might not be suitable for puppies or kittens of a certain age. That way, it is important to read through the label carefully.

Spray

Sprays are another effective type of flea medicine in protecting your furry pal against recurring flea infestations.

They are also designed for use in your yard or home. All you have to do is spray your dog’s entire fur.

They also contain insecticides whose purpose is to kill fleas of all life stages they encounter.

Applying flea sprays requires some care, such as the mouth and eyes. Apply with care so that you don’t end up adding to the hurt your dog already feels.

Powders

This is a unique type of flea medicine for dogs. Rather than using them on your furry pal, you apply them in your home.

But, just like the other types, they contain a variety of natural and chemical insecticides. You have to sprinkle on your upholstery and carpets, brush in and allow for some hours before you vacuum.

This way, it kills every flea and any laid eggs it comes in contact with.


 

What To Consider When Choosing Best Flea Medicines For Dogs

Purpose of Product

We have already established that there are countless numbers of flea medicines in the market, and certainly, they all come with different purposes.

For instance, some are for preventive purposes and act as flea repellants. Others are specialized in eradicating fleas in their developing stage, like larvae.

You also have medicines that are primarily designed to terminate adult fleas.

Active Ingredients

Flea medicines for dogs are generally a combination of substances and ingredients. Different medicines come with different ingredients, and even among these ingredients, some are the major.

Also, certain dogs can react to certain ingredients differently. You want to be aware of your dog’s allergy and avoid treatments with those ingredients.

At the end of the day, the effectiveness of an ingredient is subject to personal opinions, but popular ones include Afoxolaner, Fipronil, Fluralaner, Nitenpyram, and Spinosad.

Potential Side Effects

It is true that most flea medicines have been considered safe by the FDA and may only have mild side effects, but as I have already mentioned, some flea medicines can cause significant and consequential side effects such as seizures.

This is especially true of certain forms of topical treatments. This may not be rampant and common but should very well be considered to avoid harm/regrets.

Flea medicines are meant to protect your pets and not cause them harm.

Specifics of your Dog

You must have known by now that the best flea medicines for dogs are not a one size fits all solution. Different dogs, for certain reasons, may react differently.

1. Your dog’s age: Generally speaking, most flea treatment products are not considered safe for dogs below, say, 7 weeks of age.

For this reason, it is important to either consult a specialist or check the product’s label to be sure it says to administer to puppies lower than a certain age.

This also applies to very old dogs, as some preventives may likely have adverse reactions to them.

2. Your dog’s weight: Another specific of your dog that impacts your choice of flea medicine is their weight. This information may likely be seen on the product label.

Administering a product meant for a small-sized animal to a big-sized animal and vice versa is bound to be either ineffective or destructive.

For the former, it may not be enough to produce the needed result. For the latter, it may be toxic to them.

3. Your dog’s medical condition: It is important to take care of dogs with a medical condition. This goes beyond allergies but other forms of health conditions.

For instance, there are some treatments not suitable for pregnant or nursing dogs.

Should they be on another ongoing medication, you want to certain the flea medicine will not interfere, disturb, or disrupt.


 

Final Words On Best Flea Meds For Dogs

Getting rid of fleas has been a battle of the age. Outlined above are some of the best options you will ever find, and they all do a great job at getting rid of those blood-sucking pests.

But, the best overall is the K9 Advantix II Flea and Tick Prevention for Large Dogs.

It is vet-recommended and thus safe for your dogs. All it needs is just to make contact with the fleas, and they’ll be all dead.

It is easy to use and generally goes gentle on your dog’s coat. It contains active ingredients popular for its anti-flea properties and action.

It might not be an all-natural treatment, but there are little to no side effects. What more could you want from a dog flea treatment.

I hope that the information provided in this post helps get you started on finding the best flea medicine for your dogs.
