Two common flea species include:

  • cat flea (Ctenocephalides felis), and the
  • dog flea (Ctenocephalides canis). [3]

With fleas having the ability to result in an enormous amount of aggravation, causing severe irritation in both animals and humans, it’s best to use preventative measures to stop fleas in the first place. Good flea treatments need to be safe, effective, and easy-to-use.

Choosing the right flea treatment

That said, how does one find the right flea treatment to use?

The best flea and tick treatments need to be safe to use around children, people, and other pets. They should also be priced reasonably and be effective for at least 30 days. It’s best to first research the ingredients before purchasing a new product to make sure that they are safe to use on your dog.

Today, there are still three main types of flea and tick treatments, which are the most popular and widely used throughout the world.

Dr. Matt Carriker answers some common questions regarding flea treatments

Oral Flea Medications

These are terrific in that they are easy to administer without any mess. Flea meds contain insecticides that are delivered into the dog’s bloodstream [4] in a short amount of time. When fleas and ticks do bite your dog, they will die right away because they are ingesting the insecticide.

Spot-On

These work by applying the concentrated liquid formulas between the dog’s shoulder blades. The medication takes 24-hours to dissipate into the dog’s skin oils, thus killing all fleas that come into contact with the skin.

The spot-on is effective for up to one month and helps prevent new outbreaks for the same period of time.

Flea Shampoos

These work by killing fleas when they come into contact with the medicated product. Before using another flea treatment product in conjunction with the flea shampoo, it’s best to consult your veterinarian for advice.

These shampoos contain chemical ingredients which may be harsh on your dog’s skin, so it’s vital to follow the recommended directions when using any flea shampoo. Most flea and tick medications make use of a pesticide, and it’s always recommended that you research the pesticides, although they are all approved by the EPA.

The National Pesticide Information Center (NPIC) discusses using pesticides on pets, and all the side effects that these pesticides may cause. The NPIC also advises that all directions need to be carefully read and followed. If your pet should become ill after administration of the pesticide you are asked to report the incident to the NPIC.

Dangerous ingredients to avoid

Three miniature longhaired Dachshunds

Pesticides, which make up the main ingredient of most all tick and flea products, can cause various adverse reactions, and it’s best to do your homework regarding these poisons. It is best to avoid the ingredients mentioned below and check the packaging for the inclusion of these in your products.

Pyrethroids

Pyrethroids [5] are organic compounds comparable to natural pyrethrins found in some flower blooms, such as the Chrysanthemum. These compounds are found in a large amount of commercial household insecticides, and overexposure in humans can lead to the following symptoms:

  • itching
  • burning
  • numbness
  • stinging.

Tetrachlorvinphos

Tetrachlorvinphos [6] is an organophosphate and overexposure may cause serious side effects like:

  • confusion
  • nausea
  • possible coma and death.

It’s important to read up on all flea and tick collar ingredients before using them on your furry best friend.

Pyrethrin

A mixture of six chemicals which are lethal to insects and some documented side effects to humans and pets. [7] Pet owners need to educate themselves about the pros and cons of certain flea and tick meds prior to applying or using on their dogs.

Tips from the NPIC when using flea & tick products

Here are some tips from the National Pesticide Information Center to keep in mind when using flea treatments on dogs:

  • follow the label closely
  • never give more than the prescribed dosage
  • certain pesticides are more toxic than others
  • products made for adult dogs should not be used on puppies
  • pet parents need to wear protective clothing if is necessary like gloves
  • do not use a flea/tick shampoo on your dog’s skin, and combine it with another flea and tick product
  • for multiple pets using flea and tick spot-on products or shampoos, it’s best to separate them to avoid licking and ingesting the product from each other
  • it’s always best to consult with your veterinarian as to their recommendations.

Multiple flea and tick products are regulated by the Food and Drug Administration, and because some of these are considered pharmaceuticals, you can look them up on the FDA website. [8]

Finally, if your dog has life-threatening side effects like:

  • seizures
  • unconsciousness, or
  • inability to breath,

. . . it’s vital to visit your closest emergency veterinary clinic. The NPIC also has an emergency helpline number to call in case of an emergency (1-800-858-7378).

Final say on flea treatments for dogs

Dogs should always be checked for fleas and ticks, most especially after they’ve been outside for a long walk. Pet parents should remove ticks with a tweezer. By brushing your dog regularly, you’ll be able to check for ticks and fleas.

All dogs need to be treated regularly with an effective, safe, tick and flea control product. If you’re living in a tick-infested area, it’s best to ask your veterinarian about the vaccination, to help prevent Lyme disease. [10]
