Repel fleas, ticks, and mosquitoes with Wahl’s Flea & Tick Shampoo for dogs. This flea and tick prevention shampoo is a safe and effective option for keeping your four-legged family member safe from unwanted pests and the diseases they carry. Gently clean your pet’s coat with plant-based ingredients and EPA-approved non-toxic essential oils that will not wash off topical flea and tick treatments. Free of sulfates, phthalates, and formaldehyde, this paraben-free shampoo’s eco-friendly packaging contains 55% less plastic than Wahl’s traditional pet shampoo bottles. You’ll love the easy, one-handed operation of Wahl’s new flexible squeeze packs so you can keep one hand on your wiggly pup while shampooing. Enjoy the self-sealing feature that prevents leaks and spills, even when accidentally knocked over.
