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
- Red spots or pustules
- Round crusty patches
- Greasy or moist skin
- Thinning coat
- Sour or sweetish smell
- Scratches or licks more
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.
