Overview
["This 16.9 fl oz bottle of Douxo S3 SEB is the larger-size version of the brand's seboregulating shampoo, built around 0.5% Ophytrium to help support skin affected by dandruff, unpleasant odors, and oily or flaky patches in dogs and cats. It's the same core formula as the smaller 6.7 oz bottle, just sized for owners who bathe their dog regularly for an ongoing skin issue.", "The shampoo is labeled hypoallergenic and paraben free, phthalate free, and sulfate free, which matters for dogs already dealing with sensitive, reactive skin on top of oiliness or flaking. It's approved for use on both dogs and cats.", 'At $35.99 for 16.9 ounces, the per-ounce cost works out lower than the smaller bottle, making this the better value if you already know the formula suits your dog. With 652 reviews and a 4.6 star average, plus around 500 units bought in the past month, it has a smaller but steady following, likely made up of repeat buyers restocking a formula they trust.']

Performance notes
Since this is the same Ophytrium-based formula as the 6.7 oz version, performance for managing dandruff, odor, and oily or flaky skin should be consistent between the two sizes, with the larger bottle simply reducing how often you need to reorder. This isn't veterinary advice, so persistent dandruff or odor is worth having a vet check for an underlying cause.
What buyers say
With 652 reviews averaging 4.6 stars and around 500 units bought in the past month, this larger size sees less volume than the smaller bottle but holds the same rating, suggesting it's mainly bought by owners already sold on the formula.
