Our scorecard

The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other dog and cat food, health, gear and grooming we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.

Overview

This earthbath shampoo ships in a 2.5-gallon size and dilutes at a 33:1 ratio, which means the bulk container turns into a large volume of usable shampoo once mixed. It's built as a gentle, fragrance-free, cruelty-free formula for sensitive skin, and it's made in the USA.

The label markets it specifically as a dog shampoo rather than a cat product, so while it appears in a cat shampoo lineup, cat owners should know it wasn't formulated or labeled with cats as the target species. It's a better fit for households or professionals bathing dogs in volume, where the diluted cost per wash is low.

With 1,800 reviews and a 4.7 rating, it's clearly a trusted product in its own category, even though recent purchase activity looks slower, likely because a 2.5-gallon bulk size isn't a frequent repeat purchase for most households.

Performance notes

The 33:1 dilution ratio and 2.5-gallon container point to a product designed for volume grooming rather than occasional home baths. The fragrance-free, hypoallergenic formula is aimed at sensitive skin, but the dog-specific labeling means cat owners should weigh that against options actually built for cats.

What buyers say

A 4.7 rating from 1,800 reviews shows strong satisfaction among its buyer base, though softer recent purchase activity suggests it's a slower-moving, bulk purchase rather than a frequent restock item.
