What to Consider When Picking the Safest Flea Treatment for Dogs







It’s important to remember that no two pets are alike. As a result, a product that is widely thought to be healthy flea and tick prevention for dogs may be perfect for one animal but disastrous for another. Consider the following factors:

  • Age: Flea remedies must be age-appropriate; many are not suitable for puppies under the age of six months. This detail can be found on the product’s name.
  • Breed: The type of coat you have can influence your decision. Topical treatments can be difficult to apply to thicker coats.
  • Other drugs or supplements you offer your pet, concurrent health problems, and prior responses to flea and tick preventatives should all be considered. When large doses of ivermectin (a heartworm preventative ingredient) are combined with spinosad, a flea preventative ingredient, dogs have developed neurologic issues.
  • The presence of children and other pets (especially cats) in the home, as well as your pet’s daily activities and exposure to the outdoors, are all important considerations.
  • Where do you reside: In your country, what parasites are common? Is there a question about resistance to such preventatives?

Your veterinarian will consider these factors while advising you on the right flea and tick preventative for your dog.

Since many of the safest and most reliable solutions include a veterinarian’s prescription, it’s best to have this conversation as soon as possible.

Flea Treatments for Dogs of Various Types

To fully secure their patients, veterinarians usually prescribe dog flea and tick collars, topical flea and tick remedies, or oral flea and tick medications (sometimes in combination). Here are some of the best flea remedies for dogs currently available, along with some of their benefits and drawbacks.

Collars for Dogs with Fleas and Ticks

Newer dog flea collars are healthy choices for flea and tick prevention in certain situations (unlike older collars, which were largely ineffective). Right now, the Seresto collar is a very common option.

It kills fleas and ticks at various stages of development with flumethrin and imidacloprid. The collar’s effectiveness lasts for 8 months (as long as it isn’t exposed to water), making it a practical alternative to monthly preventative treatments.

If you have small children, don’t let them play with the Seresto collar or the reflector clips that come with it. Since both flea and tick collars appear to leave traces of the chemicals that make them successful in the dog’s environment and on your pet, this may be a problem for small children who like to eat anything.




Local skin reactions to the collar have occurred in some dogs, which have resolved once the collar has been removed. “Consult your veterinarian before using this product on debilitated, elderly, raising, pregnant, or nursing animals,” Seresto’s product insert adds. Both flea and tick preventatives fall under this category.

Treatments for Fleas and Ticks on Dogs’ Skin

There are many effective flea remedies for dogs that are topical (or spot-on), and several of them protect against more than just fleas.

Advantage Multi, for example, is a prescription drug that kills heartworms, hookworms, whipworms, roundworms, sarcoptic mange mites, and fleas with the active ingredients imidacloprid and moxidectin. Ticks aren’t killed by it, and dogs shouldn’t be able to lick the application site for at least 30 minutes to prevent significant side effects.

Frontline Plus is an over-the-counter flea and tick treatment that uses fipronil and (S)-methoprene to kill fleas and ticks at all stages of their life cycle. It also helps to combat sarcoptic mange infestations and prevents chewing lice. Although it should not be consumed, a few covert licks from your dog won’t cause too many problems.

A topical treatment, including flea and tick collars, may not be the best option if you can’t keep your pet away from small children or animals that may come into direct contact with the drug until it has dried or absorbed into your pet’s skin.




If you have cats, you can consult a veterinarian before selecting a topical flea and tick treatment for your dog. Some contain pyrethrin or permethrin, both of which are extremely poisonous to cats.

Bathing a dog should be done several days after the filing. Topical therapies are usually applied once a month.

Dogs’ Oral Flea and Tick Medications

There are a number of prescription oral flea and tick drugs that are considered healthy for dogs. These preventatives are available as pills or chewables. Your veterinarian will assist you in determining which one is appropriate for your puppy’s age.

Trifexis uses spinosad and milbemycin oxime to protect dogs from heartworms, intestinal parasites, and fleas, but it is not effective against ticks. This medication must be prescribed by your veterinarian.

Bravecto chews (also available as a topical) provide flea and tick protection for 8-12 weeks per dose. Fluralaner is the active ingredient, and it destroys adult fleas and ticks. Bravecto also needs a veterinarian’s prescription

Oral flea and tick treatments are ideal for families of young children or other small pets that may come into contact with the drug.

Vomiting is the most common side effect of prescription oral flea drugs.




There are side effects of any drug, but leaving parasites untreated is much more harmful. Depending on your dog’s age, lifestyle, health status, and other specific characteristics, your veterinarian will help you choose the best and most appropriate flea and tick treatment.
