Overview
An oatmeal-based liquid shampoo formulated to treat fleas and ticks on dogs, sold in an 18 oz bottle. Oat is listed as the active ingredient.
The oatmeal base points to a formula meant to soothe skin while treating fleas and ticks in the same wash, rather than a purely insecticidal shampoo. It is labeled for all life stages, so it covers puppies through adult dogs, and the listing notes it is free of cashew allergens specifically. Best-sellers data shows it ranked inside the top 20 dog shampoos on Amazon at the time of listing.

Who it's for
Dog owners treating an active flea or tick issue who also want a shampoo gentle enough for regular bathing, given the oatmeal base. Owners looking for a purely cosmetic or fragrance-focused shampoo may want a different product.
