Which medicated shampoo does your dog's itchy skin need?

An itchy, red, flaky patch on your dog could be a fungus, bacteria or mites. They look the same but need different treatment. Get a quick skin test at a vet before you buy anything, and don't start with a steroid lotion until you know which one it is.

Key Takeaways

• Fungus, bacteria and mites all cause the same itchy patch. A quick skin test at a vet tells them apart.
• Leave medicated shampoo on the skin for the time on the label, usually around ten minutes, or it won't work.
• Don't start with a steroid lotion. It stops the itch but can hide an infection that keeps spreading.

Why skin problems start after the rains

Yeast and bacteria live on healthy dog skin all the time. They only cause trouble when the skin stays warm and damp.

After the monsoon, dogs come home from walks a little wet. The coat dries quickly, but the skin under the collar, in the armpits, between the toes and inside the ears stays damp. That's where problems start, which is why we see more skin trouble in the weeks after the rains than during them.

Bathing more often with ordinary shampoo makes it worse. It strips the skin's natural oils, and it leaves the coat damp more often.

What the itchy patch might be

• Ringworm is a fungus, not a worm. It's often a round patch of hair loss with a scaly edge, and it isn't always itchy. It can spread to people, so watch for a round, scaly patch on anyone at home.
• A hot spot is a bacterial infection: a wet, red, smelly patch that appears almost overnight, sometimes with small pus spots. Something else usually sets it off, so it tends to come back unless that is found.
• Mange is caused by mites. The dog scratches far more than the skin looks like it should. No shampoo clears mange. It needs a vet's treatment.
• Flea allergy shows over the lower back and the base of the tail. One flea bite is enough, so not seeing fleas doesn't rule it out.
• Yeast makes the skin greasy and sour-smelling, and leaves brown stains on paws the dog keeps licking.

You can't tell these apart just by looking, and neither can we. A skin scrape or tape test takes a few minutes at the clinic and shows which one it is.

Which product for which problem

Medicated shampoo is the right start when the problem covers a lot of the body. Virbac Ketochlor at Rs 349 treats fungus and bacteria together, which matters because the two often turn up at the same time. Vivaldis Viv Keto Forte does the same job for Rs 250.

The most important part is leaving it on. Lather it in, then wait for the time on the label, usually around ten minutes, before rinsing. A normal quick bath does almost nothing. Set a timer on your phone. And finish the full course, even once the skin starts to look better.

Antiseptic spray such as Savavet Chlorhex at Rs 185 is for one small spot, or between baths. It doesn't replace the bath when the problem is widespread.

Iodine spray like Venkys Iopaint at Rs 35 is for cuts, grazes and patches your dog has chewed open. On generally itchy skin it stains, dries the skin and does nothing for yeast or mites.

Steroid lotions need care. Wokazole Plus at Rs 81 works fast because it contains a strong steroid, and that is also the risk. On ringworm or mites it stops the itch while the infection keeps spreading underneath, and it makes the skin harder for a vet to read later. It's a prescription product. Use it after a diagnosis, not instead of one.

Homeopathic drops such as Dermisule at Rs 414 don't kill fungus or bacteria. If you want to use them, use them alongside proper treatment, never in place of it.

Antifungal and antibiotic tablets need a vet's prescription, so we don't give doses here.

How to stop it coming back

Dry your dog properly after walks and baths, especially the skin folds, under the collar, the armpits, between the toes and inside the ears. Let the air finish drying before the collar goes back on.

Wash your dog's bedding in hot water, because ringworm can survive in a home for months. And keep flea prevention going, even if you've never seen a flea.

When to see a vet

See a vet if the patch is still spreading after a week of treatment, if it smells, if the skin is open or bleeding, or if the itching keeps your dog awake. Go too if anyone at home gets a round, scaly patch.

Ears need a vet first. If your dog keeps shaking its head or has a smelly brown discharge, don't put anything in the ear until a vet has looked inside it.

Our clinic is next to the store in Gachibowli, so the test and the right product can happen in one visit. Please come early. Skin that has had weeks of home treatment is much harder to read.

The research behind this

This page is based on what we see at our clinic and on the product labels. Here is what is actually in each product, taken from the labels.

Virbac Ketochlor pairs ketoconazole, an antifungal, with chlorhexidine, an antibacterial. Wokazole Plus lotion contains four ingredients: ofloxacin, miconazole, zinc sulphate and clobetasol at 0.025%. Clobetasol is a potent corticosteroid, which is why the lotion calms a patch so quickly, and why prolonged use on open wounds should be avoided. Venkys Iopaint is povidone iodine, a wound antiseptic.

Medicated shampoo labels ask for the lather to stay on the skin for between five and fifteen minutes, depending on the brand, before rinsing.

Frequently Asked Questions

How long should I leave medicated shampoo on my dog?

For the time printed on the label, usually around ten minutes. Lather it in, wait, then rinse. A quick bath doesn't give the medicine time to work.

Can I put a steroid cream on my dog's itchy skin?

Not before a vet has seen it. A steroid stops the itch but can let ringworm or mites keep spreading, and it makes the problem harder to diagnose.

Can ringworm pass from dogs to people?

Yes. Ringworm can spread between dogs and people. Wash bedding in hot water, and see a doctor if anyone at home gets a round, scaly patch.

अक्सर पूछे जाने वाले सवाल

कुत्ते पर दवा वाला शैम्पू कितनी देर लगा रहने दें?

डिब्बे पर लिखे समय तक, आमतौर पर लगभग दस मिनट। झाग लगाकर इंतज़ार करें, फिर धोएँ। जल्दी से नहलाकर धो देने पर दवा को असर करने का समय ही नहीं मिलता।

क्या कुत्ते की खुजली वाली जगह पर स्टेरॉयड क्रीम लगा सकते हैं?

पहले vet को दिखाए बिना नहीं। स्टेरॉयड खुजली तो रोक देता है, लेकिन अंदर फंगस या माइट्स का इन्फेक्शन फैलता रह सकता है, और बाद में बीमारी पहचानना मुश्किल हो जाता है।

क्या कुत्ते का रिंगवर्म इंसानों को भी हो सकता है?

हाँ, रिंगवर्म कुत्ते से इंसान में फैल सकता है। कुत्ते का बिस्तर गरम पानी में धोएँ, और घर में किसी को गोल, पपड़ीदार दाग दिखे तो डॉक्टर को दिखाएँ।
