Should you use flea medicine for your dog?

If the flea infestation on your dog is advancing, you need a flea medicine to get rid of it. Aside from flea shampoos, medicines – either topical or oral – will boost its effect. Flea medicines prevent the parasites from spreading, not to mention saving your dog’s coat from injuries.

Take note that fleas can cause severe dermatitis, Bartonella, and even anemia. This is why you have to act fast before the parasite compromises your dog’s health.


Type of flea treatments for dogs

Take note that there are different types of flea treatment. Not each one is suitable for every dog, so it’s important to know each one and to ask the opinion of a veterinarian. To give you an idea, here’s a quick look at each one:

*Flea pills

Flea pills, tablets, or chews are one of the most popular solutions for fleas. This is packed with medication that spreads through your dog’s bloodstream. So when the flea bites, they will suck the blood with medication. This will either kill them or stop their reproduction.

Aside from exterminating fleas, some of these pills are combined with other substances that treat other parasites like heartworm, whipworms, and roundworms.

Moreover, flea pills may have different active compounds. Here’s a quick look at the most common types:

Nitenpyram. This is an over-the-counter pill with a fast-acting nature. It starts to work within 30 minutes upon ingestion and will keep working for a maximum of 48 hours. Within 4 hours, nitenpyram can kill up to 90% of all the fleas on your dog’s skin.

Fluralaner. This new pill can kill both adult and juvenile fleas within 8 hours. Unlike nitenpyram, fluralaner lasts for up to 12 weeks for every ingestion.

Spinosad. This is another popular flea medicine that has the same effect as nitenpyram. However, some dogs experience vomiting as the side effect of this drug.

Afoxolaner. This pill kills adult fleas and lasts for up to 30 days. 

*Topical solutions

Aside from pills, you can also opt for a topical treatment for fleas. These are liquid-form agents that you have to apply at the back of your dog’s neck and shoulder blades. This can be used to exterminate a current infestation or as a preventive treatment.

Take note that topical flea treatments will have different active compounds. Also, the choice would be dependent on your dog’s size and overall health.

*Flea sprays

For minor flea cases, pet owners have the option to use flea sprays instead of giving their dog oral or optical medicines.

Flea sprays are usually made of natural extracts made to repel fleas on your dog’s coat. Also, it’s safe to spray all over your dog’s torso, neck, and legs. However, it offers the least coverage as compared to the best flea medicine for dogs.

*Flea collars

Lastly, there are flea collars. This isn’t your typical dog collar as the band is infused with slow-acting medicine that will kill the fleas all over your dog’s coat in several days. Take note, however, that flea collars aren’t meant to be used on a leash.

Overall, flea collars are economical and can last for months.


Do you need a vet prescription?

For the oral flea medications, you don’t necessarily have to secure a vet prescription. However, it’s always best to consult the dog doctor first before giving the pill to your pooch.

Each dog will have varying reactions to a specific drug. To prevent any potential side effects, you should seek the supervision of a veterinarian.


Best Flea Medicine for Dogs – Buying Guide

*Period of protection

The first thing you have to consider for the best flea medicine for dogs is its period of protection. Usually, flea pills have the shortest coverage, though it acts within minutes. On the other hand, topical flea medicines have a better coverage period. A slow-acting flea medicine usually offers a longer coverage.

*Waterproof features (for topical solutions)

For topical treatments, waterproof formula is the ideal choice. This way, the efficacy of the treatment will remain intact even as you bathe your pet.

*Dosage (for oral solutions)

If you’re using an oral flea treatment, you have to be specific with the dosage to prevent any harsh side effects. Pups need a lower dosage, while older and larger breeds will require a higher dose so it will be effective in killing the fleas.

*Types of parasites covered

Aside from fleas, most flea medications can also get rid of other parasites like ticks, mosquitoes, lice, and worms. This way, you only need to use one product to cleanse your dog of parasites and to provide a complete parasite coverage.

*Safety

No matter how potent the flea medicine is, you should always prioritize the safety of your dog. This is only possible through vet supervision and careful selection of the medication.

*Ease of application

This may not be a big deal, but it’s worth finding a flea medicine that’s easy to apply. With this, you won’t have to deal with the mess and no flea medication will be wasted.

*Smell

For topical medication, the best flea medicine for dogs is one with a subtle to no smell. Remember that dogs have a very strong sense of smell and a pungent odor from the medication may cause irritations.
