best dog flea dropsAs a dog owner, both me and you have been through this before. One anti-flea product works so well, and then a year or two later it’s just not cutting it anymore. That’s not surprising, and it's not always due to the effectiveness of dog flea or tick treatments.

Dealing with fleas on a dog

best dog flea dropsWe've previously discussed fleas on dogs in a very extensive article, and also have a video guide on how to get rid of fleas on a dog. But to better understand how to choose the best dog flea treatments, we must first discuss how fleas and ticks attack our dogs and what do they do.

Fleas have extremely strong hind legs, which means they can jump upwards of 5 inches vertically and 8 inches horizontally, according to FleaScience.com website. They are parasites, which means they need to live off of a host to survive (in this case, your dog is the host). Once fleas are on your pet, they will bite her and suck her blood for nutrients.

The best case scenario is that these flea bites will simply cause your dog some itching and discomfort. The worst case scenario is that your dog may be allergic to flea bites, which could result in inflammation, hair loss or secondary skin infections among other issues.

How to choose a safe dog flea treatment

Preventing fleas is quite easy, as there are so many different options to choose from. From flea collars for dogs to sprays, preventative flea shampooss and topical treatments to prevent fleas on your dog (the host). Once your dog already has them, you may need to look into carpet flea sprays and dog flea powders to treat your home. Ultimately, there is a method of prevention and cure that will meet your needs and budget.

The downside is that if not chosen carefully, a lot of these measures contain toxic chemicals that can make your dog ill, cause more skin irritation than the fleas themselves, or even lead to certain types of cancers.

Topical flea treatments for dogs have been linked to many serious health conditions in dogs. Thus, it's important that you observe your pet closely for the first 24-48 hours after applying any topical treatments, even if using these best dog flea drops.

After you apply any type of flea treatment to your dog, symptoms to watch for that may indicate your dog was poisoned by those flea products include:Dog flea closeup

  • salivating
  • dilated pupils
  • tremors
  • vomiting
  • hiding
  • shivering
  • skin irritation

A study done in 2008 by the Center for Public Integrity found at least 1,600 pet deaths related to spot on treatments containing pyrethroids were reported to the EPA over the previous five years. It was also reported that these types of topical treatments account for more than half of “major” pesticide pet reactions reported to EPA over those same five years. Major reactions included those involving serious medical reactions like brain damage, violent seizures and heart attacks.

Unfortunately, there are no chemical based flea and tick treatments that can say they are 100% safe with no known side effects, and any natural treatments are unlikely to be very effective. That's why it is critical for your pet's health that you do exceptional research before choosing any topical dog flea treatment to use on him.

Discuss your options with your veterinarian, mention these best dog flea drops we discuss below, and research every product available extensively. Look into the manufacturer to find out where their products are made, what chemicals are used in the products and if there have been any recalls or lawsuits filed against them or their products.
