What To Look For in Dog Flea Pills

Safety for pets and people

Flea pills use a form of pesticide to wipe out fleas. The best flea pills for dogs should be safe enough to use around children and other pets. The active ingredient used should be approved by the Environmental Protection Agency (EPA). Otherwise, it might cause serious effects in humans and animals. A small number of dogs have been reported to experience minor side effects as an initial response to the medication. This includes drooling, loss of appetite, and sluggishness that could only last for a few days. Talk to your veterinarian so he can determine any hypersensitivity in your dog.

Class formulation

Choose a formulation that is recommended for your dog’s age and weight.

Maximum killing action

Look for a brand that is labeled broad-spectrum. The efficacy of a flea pill is anchored on its ability to target fleas of all life stages in one easy-to-use form. It should kill adult fleas, and larvae, as well as inhibit eggs from growing. The best brands can even kill ticks.

Quick onset & long-lasting effects

Fleas are amongst the most resilient ectoparasites. You may kill some today but you will find some crawling on your dog a few days later. Thus, opt for a product that offers a quick onset of action and long-lasting effects.

Dog’s preference

Just like kids, dogs won’t gobble something they don’t like. You can stuff the pill in a hotdog or coat it with peanut butter, but a flea pill tasting like beef will be enthusiastically received!

Personal convenience

Some pills are designed for monthly or daily administration. In the end, the type of flea pill that is best for your dog depends on your situation.

Benefits of Flea Pills for Dogs

Faster killing action than spot-on treatments

Flea pills are particularly helpful for dogs who are suffering a heavy infestation that needs to be addressed as quickly as possible. You won’t have to wait a day or two for the medication to take effect. Once the pill is ingested, the active ingredient gets metabolized and circulates throughout your dog’s body. It kills every flea that feeds and clings onto your dog. Therefore, this type of medication is considered more effective compared to spot-on treatments.

All-in-one protection

In the past, fur parents had to buy separate products to prevent various pests from vexing your pet. This can be expensive and inconvenient, especially for families with multiple pets. The good news is that flea pills can do more than just kill adult fleas. It can eliminate fleas in all life stages along with ticks. It also prevents mosquitoes from biting your pet.

No mess and hassle-free administration

Many fur-parents prefer flea pills to spot-ons because the administration is more convenient. Flea pills are soft and deliciously flavored, which makes it easy to give to your dog. Dogs can be bathed or are allowed to swim like mad after administration since it’s not topical. Most importantly, it doesn’t leave a nasty smell and a sticky mess if your dog lollygags on your bed.


Fleas are downright frustrating! Though very small, these parasites pose a big threat to the family, particularly to our furry family members. Prevention is the best course of action, but sometimes, it is inevitable for your pet to contract an infestation.

If you suspect your canine buddy has contracted fleas, be sure to address the problem immediately with the best flea pills for dogs. Don’t wait for flea allergy dermatitis, tapeworms, and other conditions to inflict on your dog.

We highly recommend the Capstar Flea Treatment for Dogs and Cats. A single dose of this oral medication is potent enough to kill existing fleas that pester your pet. Take note that its flea-killing action does not rely on pyrethrin and organophosphates, both of which are known for being harsh. This product is FDA and EPA approved.

This treatment is also ideal for homes with multiple pets with different age groups. Although it works spectacularly against heavy infestations, you may have to invest in a flea preventative medication for a long-term fix.
