Skin infections

Skin infections are caused by bacteria or yeast that start to multiply when the skin's defences are weakened, for example by an allergy, parasites, moisture trapped in skin folds or constant scratching. An infection can stay on the surface or reach the deeper layers of the skin, causing pain and intense itching. What caused the infection and what keeps it going is for a vet to work out.

What it is

Healthy skin is a tough barrier with its own bacteria and yeast living quietly on it. Trouble begins when that barrier is damaged: an allergy leaves the skin red and itchy, the dog scratches, tiny breaks open up, and microbes that were harmless guests start to multiply. Warmth and moisture help them along, so skin folds, armpits, paws and ears are the places to watch.

An infection points to something underneath that let it start, such as an allergy, parasites, a hormone disorder or skin folds that stay damp, and it can come back while that cause is still there.

A quick look at the skin while you brush or cuddle your dog catches changes early. Dry your dog well after swims and baths, paying attention to folds and the spaces between the toes, and notice any new smell: infected skin gives off a sour or sweetish one that is hard to miss.

Signs you may notice

You may notice red pimples, small pustules or round crusty patches, moist or greasy areas of skin, a thinning coat or an unpleasant, sweetish smell. The dog may scratch or lick more than usual.

When to see a vet

Book a visit if a rash, smell or itch lasts more than a few days or keeps coming back. A hot, swollen, painful patch, or a dog that seems unwell with it, should be seen promptly.

This is general information, not veterinary advice. For your own dog's health, tests and treatment, see a vet.
