Best Flea Shampoo for Dogs: Why PawPurity® Is the Trusted Choice
Fleas aren’t just a nuisance — they’re a real health risk. According to the FDA, “Fleas and ticks can carry and transmit serious diseases to pets, and to people too. That’s why controlling fleas and ticks is important.”
And the CDC warns: “Flea infestations can cause severe anemia in pets and can spread disease-causing pathogens such as Bartonella.”
That’s why choosing the right flea shampoo matters. Many products on the market, including some labeled “natural,” contain toxic chemicals that can irritate your dog’s skin, disrupt their health, and even cause harm if licked off during grooming. PawPurity® Natural Flea & Tick Shampoo offers a safer, proven alternative with natural botanicals, organic oils and minerals that repel fleas while healing and protecting your dog’s skin.
Why Flea Shampoo Matters for Dogs
Dogs that spend time outdoors are constantly exposed to fleas. Even a mild infestation can multiply rapidly, leading to itching, hair loss, infections from scratching, flea-borne illnesses, and even anemia in vulnerable dogs like puppies and seniors. Regular use of a safe flea shampoo helps break this cycle and protects both pets and households.
Many of PawPurity's customers say there are no fleas and tick in the Las Vegas Desert, where I live. However, too many come back to buy PawPurity Flea & Tick Shampoo. In chatting with a woman from the Nevada Forest Service, I asked her about this. Her answer was a definite yes, there are fleas and ticks in Las Vegas and they aren't just in the mountains. My takeaway from our conversation was:
Southern Nevada now sees more tick presence, including species that can thrive indoors
Fall remains a key season for tick activity—the risk persists beyond spring and summer
Local experts confirm increasing tick and flea activity
Don't be Fooled by Flea & Tick Shampoo Labels
Even popular flea shampoos — including some sold as “gentle” or “natural” — often rely on synthetic chemicals that carry risks:
Pyrethrins and pyrethroids – Neurotoxins that can cause tremors, seizures, and respiratory issues in dogs.
Organophosphates – Linked to vomiting, diarrhea, breathing difficulties, and neurological damage.
Methoprene and similar insect growth regulators – Can irritate skin and disrupt endocrine systems.
Artificial fragrances and dyes – Common irritants that can trigger allergic reactions and contain phthalates.
Sodium lauryl sulfate (SLS) – A harsh detergent that strips oils, leaving skin dry and inflamed.
These ingredients may kill fleas, but they do little to support your dog’s skin health — and may create new problems over time.

How to Use PawPurity® for Best Results
Wet your dog’s coat thoroughly with warm water, avoiding eyes and ears. This is not a sudsing formulation, as it has no sulfates. It does lather, however. This shampoo is highly concentrated with nutrients, organic oils, herbs, nuts and minerals. You only need to use a little. Massage shampoo deeply into the coat and skin, letting it sit a few minutes. Use a flea comb while the shampoo is lathered to pull off any live fleas. Rinse completely and towel dry. Repeat weekly or as needed for prevention.
Here is a thumbnail chart of how much to use depending on your dog's size:
- Small: 1 oz
- Medium: 2 oz
- Large: 3 oz
- Extra large: 4+ oz
