How we tested these 5 products

Medicated dog shampoos treat specific skin conditions – bacterial infections, fungal overgrowth, excessive sebum, or parasites. Unlike regular shampoos, medicated formulas contain active pharmaceutical ingredients and should generally be used under veterinary direction. This guide covers the top options available in Australia, what each treats, and how to use them correctly.

What to look for – AU buying advice

When to use medicated shampoo

Medicated shampoos are appropriate when your vet has diagnosed a skin infection, fungal overgrowth, or specific skin condition that responds to topical treatment. Using an antifungal or antibacterial shampoo on a dog with simple dry skin can cause further irritation. If your dog is scratching, check for fleas first (the most common cause in Australia), then consult your vet before choosing a medicated product.

Correct contact time is critical

Medicated shampoos require a minimum contact time (usually 10 minutes) to be effective – this is very different from regular shampoos. Apply, lather, then keep the dog still (use treats and distraction) for the prescribed time before rinsing. Rinsing immediately after application dramatically reduces effectiveness.

Using with a conditioner

Many medicated shampoos are drying, as the active ingredients that kill bacteria and fungi also strip oils. Follow medicated shampooing with a veterinary conditioner (Aloveen Intensive or Episoothe leave-on) to restore the skin barrier. Never use a human conditioner as a follow-up.

Treatment frequency and duration

Follow your vet’s prescribed frequency – typically 2-3 times per week initially, reducing to weekly maintenance. Do not stop treatment when the skin looks better – yeast and bacterial populations can rebound quickly. Complete the full course as directed, and follow up with your vet if there’s no improvement after 4-6 washes.

Common Questions

What is the best medicated dog shampoo in Australia?

Malaseb by Dermcare is the most trusted medicated dog shampoo in Australia – it’s the first-line treatment for Malassezia yeast infections recommended by Australian veterinary dermatologists. It’s available at Petbarn, Pet Circle and vet clinics across the country.

How do I know if my dog has a yeast infection?

Malassezia yeast infections typically present as itching (especially ears, paws, groin, armpits), a musty or corn-chip odour, greasy or thickened skin, redness and hyperpigmentation (dark discolouration of skin). Ear infections often run concurrently. A vet diagnosis (skin cytology) confirms yeast presence before starting Malaseb treatment.

Can I use Malaseb every week?

Malaseb can be used 2-3 times per week during active infections and weekly for maintenance control. It’s drying with extended use – always follow with a veterinary conditioner. Consult your vet if your dog requires ongoing weekly Malaseb use, as this may indicate an underlying condition (allergies, hormonal disorder) that needs addressing.

Are medicated dog shampoos safe for puppies?

Some medicated shampoos (like Pyohex) are safe for puppies 6 weeks and older. Always check the specific product label and consult your vet before using any medicated shampoo on a puppy under 12 weeks. Dermcare Malaseb has specific use instructions for puppies – your vet can advise appropriate dilution.

⭐ Our Pick

For Australian dogs suffering yeast or bacterial skin infections, Dermcare Malaseb is the definitive first choice – it’s what Australian vets prescribe and what groomers reach for. For maintenance after an infection clears, Aloveen Oatmeal or Episoothe provide excellent ongoing skin barrier support. Always consult your vet before starting medicated shampoo treatment.
