What are fleas?

All of the species of fleas are categorized under the name of Siphonaptera. There are many hundreds of species of fleas. They are insects that thrive in warm and moist environments. Fleas subsist on blood from the host animal, be it dog, cat, human, or anything else. Most flea hosts are mammals, in fact, 95% of all flea hosts are mammals.

Flea saliva contains an ingredient that will soften the skin of the host, allow for easier penetration, and then allow the flea to feed. It is the saliva that causes all of the itching, scratching, and similar allergic reactions.

Fleas have four stages in their life cycle, which are egg, larva, pupa, and adult. The complete life cycle can last from a couple of weeks, up to several months, depending on the environmental conditions.

Flea eggs are not sticky, and they usually fall off of the animal into carpet, soil, or any other surface. Flea eggs can hatch between two days and a few weeks. The larva emerges from the egg, and this stage actually has three developmental stages.

Larvae eat feces of adult fleas, organic debris found in the carpet, bedding, soil, and other surfaces. Depending on the food in the environment, the larval stage can last between 5 and 18 days. At that point, the larva spins a silken cocoon and pupates.

Flea pupa is the final developmental stage before the flea becomes an adult. The adult flea can emerge from the cocoon as early as 3 days, or it can stay for one year or more, waiting for an appropriate time to emerge. Humidity, warm ambient temperatures, and similar conditions and cause the adult flea to emerge sooner.

Adult fleas have a very flat body, and they have hair-like bristles on the body and legs. Adult fleas live on the animal, and their diet consists of blood meals thanks to the host animals. Female fleas lay eggs, up to 50 per day, and 500 over several months.

How to control fleas

There are different treatments for fleas on dogs. Today, we will talk about the best flea shampoo for dogs. But there are other treatments as well.

Shampoos or flea baths are usually the first attack on fleas for a pet that has a large number of fleas visible on the body.

Collars are great for preventing fleas, but also treating. They absorb into the animal’s subcutaneous fat layer. They are effective for adult fleas mostly, but can also prevent larval development.

Spot on treatments are applied between the shoulder blades of the pet and last about one month. They can treat adult fleas, but also inhibit larval development.

Pills, be it oral or injectable medications can stop the larva from emerging from the egg and break the life cycle.

What is flea shampoo?

Pet flea shampoos are special medicated shampoos that contain safe ingredients for your pet’s coat. You can use these shampoos to safely cleanse the coat of your pet, all while killing fleas and prevent them from returning.

Once you remove fleas, you will have to continue using the shampoo for one year, to ensure it is effective, and prevent fleas from returning.

Use the pet flea shampoo on infested areas as soon as you notice a problem. Your goal is to stop the flea life cycle.

You can use a flea shampoo just as regular pet shampoo, applying at the head and behind the ears, and then moving down and toward the tail. Just allow the shampoo to remain in the hair coat for five minutes before rinsing, so that it can kill any pesky insects.

Should you buy flea shampoo for dogs?

Some owners think they do not need a flea shampoo for their pet. The answer to the question “who should buy the best flea shampoo for dogs” is everyone. Your dogs can easily pick up any fleas or ticks. Even if your dog is under regular preventive measures like spot treatments and collars, he can pick up fleas.

So, with that in mind, it is nice to have it at your arm’s reach if fleas attack. Now, remember, flea shampoos are not good for dogs that do not tolerate bathing. Sadly, there are dogs that get too irritated when bathing, and they do not stay calm. If that is the case, you might be better off with another flea treatment product.

What to look for in a flea shampoo?

A good flea shampoo should do several things well.

Here are some important features you need to consider before buying the flea shampoo:

  • Efficacy, which is arguably the most important factor. Does the shampoo work? Sadly, not all flea shampoos are as efficient and effective
  • Check what the shampoo eradicates. Most work on both fleas and ticks, but just to be safe, check whether the shampoo work for ticks as well. Also, check whether the shampoo works only on adult fleas, or it can help with larvae and eggs as well
  • Some shampoos offer flea prevention as well. Those are the best, and usually, more expensive
  • Size of the package, as you will need to use the shampoo for a whole year to prevent returning fleas

How to use the flea shampoo?

You might think, using shampoo to bathe your dog is not rocket science. All you have to do is lather, rinse, and repeat, right?

Well, not quite. Flea shampoos come with specific instructions depending on the formulation. Some of them have powerful pesticides in them that should kill fleas. Therefore, be careful not to leave the foam on too long, and rinse thoroughly to protect your pet.

Here are some tips for how to bathe your dog with a flea shampoo.

  • Start with the shampoo at the head, being careful around the ears
  • Don’t set the dog in a tub of water immediately, as you do not want the fleas to head for high ground in his ears. Instead, use a shower spray to pour water over your dog
  • Leave the shampoo for five minutes at max, or less, depending on the instructions
  • Rinse your dog thoroughly to make sure you remove all of the shampoo and fleas
  • Once you rinse your dog, fill up the bath for a thorough rinse
