Our verdict

A medicated shampoo aimed at bacterial and yeast skin problems in dogs and cats, built around chlorhexidine. Contact time and frequency are not in the listing, so a vet's directions decide use.

Overview

Not a routine coat wash, Douxo S3 PYO is a medicated shampoo with chlorhexidine as its antibacterial and antiseptic agent. Ophytrium is listed as a special ingredient, and the scent is coconut and vanilla.

The listing positions it for dogs and cats whose skin has a bacterial or yeast problem, and it also claims soothing and moisturizing benefits. It is the opposite of a cosmetic shampoo, since the active is there to treat. Nothing in the listing covers how long to leave it on.

Who it's for

Owners of dogs or cats with a diagnosed bacterial or yeast skin condition who have been told to use a chlorhexidine wash. It suits a short course rather than weekly maintenance. A healthy pet does not need a medicated product.

Pros and cons

Pros
  • Chlorhexidine for antibacterial action
  • Covers bacterial and yeast problems
  • Works for dogs and cats
  • Paraben and sulfate free
Cons
  • Medicated, not for routine bathing
  • Contact time not listed
  • Small bottle for large dogs

Performance notes

Chlorhexidine acts on the skin and coat while it is in contact, so the time left on the pet before rinsing governs the effect. A thorough lather to the skin surface matters more than the amount used. Directions on the bottle or from a vet set the schedule, since none appears in the listing.
