Does my dog have fleas?

If you suspect your dog may have fleas but you’re not completely sure, there are a few examinations you can do at home. The first step is to examine your dog’s fur and skin for the presence of fleas or symptoms of flea bites. You could also brush through your dog’s fur with a flea comb. For further tips, check out our article on the 6 signs that your dog has fleas.

What are the consequences of untreated fleas?

The issues that fleas can cause will vary between dogs. Most commonly, dogs will experience intense itching and scratching as a result of flea bite dermatitis, an allergy to flea saliva. Not only is this incredibly uncomfortable for pooches, but fleas can also create internal infections such as tapeworms. These parasites are passed onto dogs if they inhale a flea.

Ultimately, it’s important to eliminate fleas as soon as you notice them for the health of your dog and others in your home.

Dog Flea Shampoo: Buyers Guide

Fleas bite and feed on a dog’s blood. Not only does this leave your dog feeling uncomfortable and itchy, but it can lead to weakness, blood loss and diseases. In fact, flea larvae can become infested with tapeworm eggs and if consumed by a dog, they can become host to this parasite. This means a dog with fleas must also be treated for worms.

Because of the potential consequences of fleas, it seems clear why it’s important to keep these parasites away. This section covers a complete buyers guide, describing everything you need to know when looking for the best dog flea shampoo.

What Is Dog Flea Shampoo?

Flea shampoos are specially formulated medicated treatments. They act as the first line of defense against fleas, quickly eliminating a large ratio of the pesky insects. High quality flea shampoos can safely cleanse a dog’s coat, soothe and relieve the itchiness of flea bites, while also killing and preventing fleas from returning. Though, shampoos will only remain effective if they are continually used as part of the grooming process.

If you notice any of the signs that your dog has fleas, it is important to treat the infestation as soon as possible to stop the flea life cycle.

Note: Although a shampoo can claim to be safe, each dog is different and will vary in reactions. Be vigilant for any adverse effects and contact your veterinarian if you spot any issues.

How to Bathe Your Dog With Flea Shampoo

Use flea shampoo in the same way as regular shampoo. Start at the head and behind the ears, and lather down towards the tail. Allow the lather to do its work by leaving it in for at least five minutes. Always follow the manufacturers’ instructions.

Tip: As with all grooming procedures, owners should help make flea shampooing a positive experience for their pup. Keep your dog busy with their favorite treats while you lather and wait patiently for the fleas to decease.

Flea Treatment Is More Than Shampoo

Using flea shampoo is a great start, but the somewhat painstaking treatment does not end there.

As mentioned previously, flea shampoos quickly eliminate a large ratioof fleas. To be specific, a large ratio can mean up to 90% of the infestation. Even the most costly and effective flea shampoos won’t be able to kill the whole flea population on your pup.

Flea infestation is likely to have grown a lot further than your dog’s fur. While fleas lay their eggs on dogs, these eggs tend to roll off around the home. This means that the fleas currently on your dog can be successfully eliminated; but as soon as they chill on the carpet or bed, the infestation will begin again. Therefore it is especially important that you also remove the fleas in your home, as well as on your pooch.

Summary: A single wash is not going to result to a flea-free dog. It is only the combination of repeated, thorough shampooing and a clean, flea-free home that will guarantee the flee of fleas!

How to Choose the Best Dog Flea Shampoo

Selecting the best dog flea shampoo can be difficult because different shampoos contain different ingredients. You want a product that contains effective flea killing ingredients but you are concerned about exposing your dog to harmful chemicals that can further irritate your dog’s flea-infested skin.

While it is true that pesticides have been associated with potential side effects, it is also difficult to ignore the fact that they are unquestionably effective. So what is the solution? Try opting for a flea shampoo that has effective insecticides that will eliminate flea eggs and adult fleas, together with soothing gentle ingredients such as oatmeal, aloe vera or coconut. These ingredients can almost act as a conditioner, which can make a dog’s coat even better than the pre-flea days!

A flea shampoo that ticks all these boxes is the Natural Chemistry Flea and Tick Shampoo.

Flea Pesticides in Dog Flea Shampoos

There are many complex chemicals listed in a flea shampoo’s ingredient list. It can be quite confusing, but it doesn’t have to be. To help you on your journey in finding the best flea shampoo, we have summarized a simple explanation for each of the pesticides commonly found in flea shampoos:

  • Pyrethrins: originated from chrysanthemum flowers and have been historically used for flea and tick control. Pyrethrins kill fleas by attacking their central nervous system to cause paralysis.
  • Pyrethroids: a group of synthetic compounds created in laboratories including permethrin, etofenprox, allethrin, phenothrin and resmethrin. These work in a similar way as pyrethrins. However, pyrethrins act more quickly and pyrethroids have longer lasting effects.
  • Methoprene: is an Insect Growth Regulator (IGR). Unlike pyrethrins and pyrethroids, methoprene targets flea eggs and larvae by preventing them from developing into adults. Only adult fleas suck blood.
Important: Permethrin is safe for dogs but highly toxic for cats. So if you’re thinking about using a dog flea shampoo on a cat, be cautious that it does not contain permethrin.

What About 100% Natural Flea Shampoos?

After all the pesticides talk, we understand if you’re thinking about a 100% natural flea shampoo. They definitely exist, but they’re not often effective enough to remove an active flea infestation. Mixtures of strong essential oils such as cinnamon, rosemary and peppermint are common ingredients in natural flea shampoos. While these cause little effect on fleas, they do have the potential to repel the tiny pests away.

Summary: All-natural flea shampoos are a great for protecting your dog against fleas. To manage an existing infestation however, we advise using Natural Chemistry Flea and Tick Shampoo or Adams Plus Flea & Tick Shampoo.
