From a veterinarian's perspective, I am extremely skeptical of your article. While bathing a dog in Dawn may be safe, cheap, and effective short-term, it is very unlikely to continue to work over time. There are many terrible commercial products available that don't work at all- I completely agree. But the prescription products work tremendously well and over the long-term. There are also products that treat fleas, ticks, intestinal parasites, and prevent heartworm all in one treatment. Finally, "Frontline" is now available as a generic "Pet Armour" that is available at Walmart and several pet stores, so you no longer need a prescription for that product. All you do is apply between the shoulder blades and vacuum the house (as 90% of the flea burden is in eggs that are in the environment). I would recommend these products over bathing the pet in Dawn and having to deal with all of the house treatments that you suggest. These products are also available for cats, which is a much easier treatment than having to bathe the cat! (which can be a total nightmare).

2) 3) The last thing you need is the flea spot treatment. This really is up to you. Everyone has their own preferences. I am currently using K9 Advantix II because it works for fleas, mosquitoes, and ticks on my dogs and Frontline plus for my cat. For extra large dogs a 6 month supply is around . (Warning: Do not use K9 Advantix on cats, it can cause illness even death on cats) You can click on images below to go directly to the page on Amazon. Here are the three most popular and in my opinion most effective ones.4) The final step is you need to determine the correct dosage. Simply open your flea treatment above and empty it into a glass vial. I would suggest washing the vials with soap and water and let them dry first. Then take your syringe and take out the correct dosage depending on the weight of your dog or cat based on the chart below.If you’re using Frontline Plus: The amount of fipronil in the dog version is the same as in the cat version. The “Plus” is methoprene, an insect growth regulator. There’s LESS of it in the dog product than in the cat product, so it’s safe to use the dog product on the cats but do NOT use the cat product on a small dog. Using a dog formulation on a cat will underdose this ingredient. An insect growth regulator, methoprene effects development of the baby fleas and may reduce long-term flea control, but not anti-tick efficacy. If you have an indoor cat, the Frontline Plus for dogs should be more than adequate if your home is flea-free. If your cat also goes outdoors, it should still be enough, just use a to check for fleas and also consider using these monthly as well to supplement the Frontline. Even with the flea pills it will still be far cheaper than buying the cat version of Frontline plus and also more effective.
