Same Formula, Different Bottles
If you're comparing Hydra Moisturizing Shampoo and Hydra Moist Shampoo, here's the short answer: they are the exact same concentrated, professional-grade formula. The difference is purely the bottle size. Hydra Moisturizing Shampoo comes in a 33.8 oz bottle, while Hydra Moist Shampoo is the larger 169 oz option.
Both are designed for dogs and cats, offering a 10:1 dilution ratio. That means one gallon of shampoo concentrate makes 10 gallons of ready-to-use wash. The formula includes oat extract for moisturizing and soothing properties, plus grape seed oil to leave a healthy natural sheen. The scent blends citrus, peach, jasmine, and amber.
Your choice comes down to volume and value. Let's look at the numbers.

Hydra Moisturizing Shampoo Sizes: Key Differences
Both products share the same ingredients and performance. The only differences are size and price. Here's how they compare.
- Volume: Hydra Moisturizing Shampoo: 33.8 oz. Hydra Moist Shampoo: 169 oz.
- Price per bottle: Hydra Moisturizing Shampoo: $19.98 (catalog comparison price $27.00). Hydra Moist Shampoo: $51.80 (catalog comparison price $70.00).

- Best for: 33.8 oz: home groomers, single-pet households, or trying the formula. 169 oz: professional salons, multi-pet households, or anyone who goes through shampoo quickly.
Which Size Should You Choose?
For most professional groomers, the 169 oz Hydra Moist Shampoo makes more sense. The lower cost per ounce and larger volume mean fewer reorders and less packaging waste. At 10:1 dilution, a single 169 oz bottle yields over 16 gallons of ready-to-use shampoo.
If you're a pet owner bathing one or two dogs at home, the 33.8 oz Hydra Moisturizing Shampoo is plenty. It still gives you over 3 gallons of wash, and the smaller bottle is easier to store and handle.
Either way, you get the same oat extract and grape seed oil formula that soothes itchy skin and leaves a natural sheen. Pair it with Hydra Moisturizing Conditioner for best results, as the manufacturer suggests.
