Fleas and other parasites are a part of every dog’s life. Every dog will have at least one encounter with pesky fleas, and hopefully, your dog could avoid getting infected. If they do avoid getting infected, you can consider yourself a lucky dog owner. As a dog owner, you should familiarize yourself with the best flea shampoos for dogs.

Contrary to popular belief, fleas are not a sign of poor hygiene or dirty home. Most dogs get infected by other dogs that have fleas, and that can happen anywhere. Dog parks are full of owners taking their dogs for some playtime. Doggy schools and daycares are another possible infection site, so you should take precautions when it comes to fleas. 

What to look for in a flea shampoo

Deciding on a flea shampoo is not as easy as it may seem. There are more than a few things to consider when picking the right brand for your dog. If your dog has sensitive skin or the flea infestation got out of hand, some weaker flea shampoos might not work. These are the most important things to look for in flea shampoo for dogs;

Active ingredients

The effectiveness of a fleas shampoo will depend on the active ingredient it contains. Most natural flea shampoos use essential oil and plant extracts, but that doesn’t mean they are not aggressive or completely safe. Just because a flea shampoo says, “natural” doesn’t mean it can’t cause a skin reaction.

Some flea shampoos for dogs will use pyrethrins or (S)-Methoprene. These are known as insect growth regulators and are often used in different flea treatments. The best thing you can do is talk to your vet and ask for advice on how to get rid of fleas.

Fleas are pretty irritating to your dog and to you. Here is what you need to know about them - Dog fleas and what to do about them.

Residual action

Some of the best flea shampoos for dogs have a long-lasting residual action. That means that not only do they kill fleas on contact, but they also protect your dog after the bath. The shampoo residue that will stay on your dog’s coat will continue to terminate fleas and even the eggs that are buried in your dog’s skin. The best flea shampoos for dogs have residual action that can last up to a month.

For dogs, cats, and puppies

This part is mostly important for households with multiple pets. Fleas are incredibly infectious, and if you noticed one of your dogs has fleas, other pets would likely get the infestation as well. Getting the best flea shampoo might mean you get one that is safe to use on dogs, cats, puppies, and kittens. You can check the ingredient list on a flea shampoo and see if it contains pyrethrins. Pyrethrins are not safe for cats.
