What is a hot spot on a dog?

A hot spot — also called acute moist dermatitis — is a sudden patch of inflamed, infected skin. It can appear anywhere on the body: hind leg, feet, rump, neck. The cause varies, but the common factor is infection — bacterial, fungal, or yeast — driving intense itching.

What triggers a hot spot?

Many things: allergies (grass, pollen, food), parasites (fleas, mites), insect bites, and even tiny scratches from a clipper blade. Some dogs are sensitive enough to simple lawn grass that they'll develop inflamed skin and hair loss after a normal walk. Biting and chewing at the irritated area turns it into a full hot spot.

What's the link between hot spots and matted coats?

Moist eczema is one form of hot spot. If the coat is dense or allowed to become matted, moisture stays trapped against the skin long enough for surface bacteria to multiply and cause an infection. Regular brushing and proper drying after baths or swims is the simplest prevention.

What does a yeast infection look like on a dog's skin?

Yeast infections create greasy, odorous, inflamed skin. Symptoms include blackening of the skin, dry flaky patches, or a greasy grit on the skin. As it gets worse, a distinct bad yeasty smell appears, severe itching kicks in, and the dog bites, chews, and loses hair.

Why does bacterial dermatitis appear so suddenly?

Healthy dog skin already carries large numbers of many bacteria — they're kept in balance by the skin's defences and by each other. When something upsets that balance — antibiotics eliminating one type, contact with grass or plastic, an abrasion, trapped moisture, or a parasite — the remaining types proliferate and opportunistic bacteria take over.

Hot Spots, Rashes and Dog Skin Irritations Explained

July 12, 2013 · Skin Conditions, Hot Spots, Dog Allergies

Hot spots, rashes and dog skin irritations — what they are, why they appear so quickly, and how to clear the infection driving them naturally.

Hot spots, rashes, and skin irritations are among the most common complaints in dogs and cats. The trigger varies, but the engine driving the misery is almost always the same: infection. Here’s how to recognise what’s happening and what to do.

What a hot spot actually is

One of the most common medical complaints in dogs and cats is the familiar “hot spot” — also called acute moist dermatitis.

There are many causes of hot spots, including allergies and parasites, but the common factor is infection — whether bacterial, fungal, or yeast (yeast is a type of fungus). A hot spot can appear anywhere on the body: hind leg, feet, rump area, neck.

The bottom line for your pet is the same regardless of how it started: there’s an infection, and there’s intense itching.

Why they appear “out of thin air”

Sometimes hot spots seem to come from nowhere. A few common triggers:

Lawn grasses — many animals are very sensitive. They look physically and nutritionally normal but show signs of inflamed skin and hair loss after time outside. If the dog bites and chews at the inflamed area, it quickly becomes a hot spot.
Minute scratches from a clipper blade — these can be enough to trigger one.
Moisture trapped against the skin — if the coat is dense or matted, moisture remains long enough for superficial bacteria to reproduce and create an infection. This is moist eczema — one of the hot-spot types.

Rashes and skin infections (infectious dermatitis)

Bacterial, fungal, and yeast organisms are notoriously obnoxious skin and coat pathogens. They cause skin infections, itching, rashes, dog dandruff, and other problems even in otherwise healthy dogs.

Bacterial dermatitis

Bacterial dermatitis rarely occurs spontaneously. Normal healthy skin already has tremendous numbers of varied bacteria present at all times. If something upsets the normal balance — antibiotics wiping out one or two types — the remaining types proliferate.

Any contact with grass, plastic, an abrasion, moisture, or a parasitic invasion can bring down the skin’s defensive barriers. After that, opportunistic bacteria have their way.

Fungal infections

Fungal infections first appear as one or more small areas of hair loss that may be reddened or inflamed. As the infection progresses, crusts form on the area of hair loss, the patches increase in number and size, and large portions of the skin can become involved.

Yeast infections

Yeast — a type of fungus — can irritate an already diseased skin surface. Yeast infections typically create:

Greasy, odorous, inflamed skin
Blackening of the skin
Dry flaky patches or greasy grit on the skin

As the condition worsens, a distinct bad yeasty smell develops, and the dog experiences severe itching — leading to endless biting, chewing, and hair loss.
