How to Choose the Most Effective Flea Shampoo for Your Dog?

3 types of Flea Shampoos for Pets

There are three different types of flea shampoos for pets that work differently for the same cause. Please note that different pet (dogs/cats) has different needs and using any of the products without proper consultation may cause harm to your pet. Here are three different types of flea shampoos for pets-

  • Chemical Flea Shampoos – the chemical flea shampoos include industry-made ingredients like pyrethroids and pyrehrins that we will discuss further in depth as we proceed with the article.
  • Natural Flea Shampoos – the natural flea shampoos include d-limonene and/or citrus peel extracts as the active ingredients. The citric acid present in the compounds besiege the fleas’ central nervous system thereby killing them.
  • Organic Flea Shampoos – the organic flea shampoos are composed of essential oils like cedar oil, peppermint oil, and clove oil that attacks and repel fleas. The organic shampoos have an added effect of cleansing and soothing your pet’s coat and skin.

Common Ingredients in Chemical Flea Shampoos

Chemical flea shampoos for pets are the most recommended when your pets is infected by these parasites. The strong chemical amalgamation is more effective in preventing and killing fleas, but the chemical shampoos carry a potential risk of adverse side effects to your pet. Therefore, it is necessary to understand the common ingredients found in chemical shampoos before using them.

Pyrethrins are active ingredients extracted from chrysanthemum plants. This natural extract has been used as insecticides for over a century. There are six different types of pyrethrins used for flea prevention, they are – pyrethrin I and II, jasmolin I and II, and cinevin I and II. Pyrethrins attack the nervous system of the fleas by disrupting the natural flow of sodium that ultimately kills them. Pyrethrins act quickly but fail to have a long-lasting effect. Pyrethrins are edible and the stomach acid can easily break them if ingested. However, it is not toxic but it is smart to keep an eye out on the symptoms.
Unlike pyrethrins, pyrethroids are synthetic compounds that are manufactured in laboratories. They are not found in nature and its five types are used in flea prevention and pest control products. Five types of pyrethroids include allethrin and resemethrin for killing flying insects and etofenprox, permethrin, and phenothrin for killing fleas.

Pyrethroids works similar to pyrethrins – attacking the central nervous system of the fleas. However, unlike pyrethrins, pyrethroids continue to repel fleas after killing them.

They work slowly as compared to pyrethrins but lasts much longer. It is advised not to use pyrethroids products on cats.

The above-mentioned two compounds are effective at killing adult fleas but the eggs and larvae remain untouched by them. This is the reason why manufacturers add a compound named methoprene in flea repellent products. Methoprene is also known as the Insect Growth Regulator (IGR) that targets the pre-adult fleas by preventing them from growing into complete adults.
Dioctyl Sodium Sulfosuccinate or Docusate Sodium
Docusate sodium is another chemical compound used in flea repellent products. It is used is most of the insect repellent products as it also prevents other insects and parasites like mites, ticks and lice. Docusate sodium works by altering the physical makeup of the fleas that causes internal organ failure.

There are natural flea shampoos for pets but the thing is they are not as effective as the chemically induced flea shampoos. Your dog or cat can still experience flea infestation even after you have used the product; it is not a complete remedy. Most of the natural flea shampoos for pets use a combination of potential essential oils like peppermint, rosemary, clove, and cinnamon.

However, the essential oils will make sure that no new infestation takes place.

It is not necessary that the product labeled ‘best’ proves best for your dog or cat. Like humans, animals are also allergic to certain natural and chemical compounds and if not given proper attention, it can cause some serious problems. Hence, here are some safety tips to consider before using any of the best flea shampoos for pets.

  • Read the product label carefully; determine whether the product is compatible for all domesticated animals or for a specific species.
  • Understand the ingredients and compound mixtures of the product. There are some compounds both natural and chemical that your pet might be allergic to. So determine the purpose of each ingredient and if any of the ingredient seems harmful, consult a vet and ask for an alternative to that particular product.
  • Before using a chemical flea shampoo on your pet, check with your veterinarian. Dogs or cats that are on medications, old, nursing, or pregnant may be at a greater risk of harm.
  • If you have used the product for the first on your pet, monitor your pet for at least 24 hours to see if they show any signs of irritation or discomfort. If your pet starts showing symptoms, it means that the product contains toxic chemicals. Symptoms of toxicity include seizures, tremors, fatigue, excessive salivation, and vomiting. If you notice anything similar, immediately contact your vet.
  • Animals react to allergic reactions differently. If your pet had a bad reaction to flea shampoo, immediately wash off your pet with warm water and soap to prevent any further discomfort and then take your pet to your vet ASAP.
  • Only use the products that are specific to your pet. You cannot use a cat shampoo for flea on your dog unless it is specified that it is safe for both the species.
  • The amount of product you use plays a crucial role as well. A little too much can cause severe bad reactions and too little can prove to be ineffective. Hence, it is important to use the recommended amount – not more and not less. Ask your vet about the quantity to be used.
  • Always wear gloves while bathing your pet and avoid direct contact from your skin. The chemical compounds may have allergic reactions on you as well. On the other hand, always wash your hands thoroughly before and after the application of the shampoo.
  • Make sure your pet is not licking its fur or skin while the product is still intact. Wash your pet until you are certain that the product is completely off its body. After washing, use an air blower or a towel to dry your pet or you can simply take it for a walk.
  • There are flea repellents products and shampoos that include ingredients like carbamates and organophosphate insecticides (OPs). These compounds are labeled carcinogenic to humans so avoid any product that has these compounds.
