Hotspot in Dogs

A hotspot is a superficial skin infection that appears suddenly and is usually localized to a specific area of your dog’s skin. This condition is very irritating for your dog because the eczema itches, which can lead to your dog spreading the eczema to other areas by trying to relieve the itch through biting and scratching.

Here’s everything you need to know about what a hotspot is, symptoms, prevention, and treatment.

What is a Hotspot?

A hotspot, also known as moist eczema or acute dermatitis, is a superficial, oozing, and acute infection of the dog’s top layer of skin. It appears as a red and irritated area with a crust on the skin, from which a sticky fluid may emerge.

Unfortunately, the infection can spread quickly, so it’s crucial to treat it as soon as possible.

Why Do Hotspots Occur?

The infection often arises from small wounds, scratches, or bites from fleas, ticks, allergies, or trauma that perforate the skin. Naturally, various bacteria live in the coat, which can access the top layer of the dog’s skin through these wounds. The thick, warm, and moist coat then provides optimal conditions for the skin eczema to flourish.

Hotspots are most commonly found on the head, neck, and ears, although they can occur anywhere on the dog’s body, frequently appearing near the base of the tail, thighs, and back.

Symptoms of a Hotspot

Moist eczema first appears as a small area of the skin’s coat exhibiting these symptoms:

·         Red and oozing areas on the dog’s skin

·         Appears very quickly; usually overnight

·         A crust forms over the skin

·         The dog licks, scratches, and bites the affected area

Hotspots are most likely to develop during the summer months when the warm and humid conditions favor infection. The dog’s coat creates the right conditions for growth as it traps moisture and heat against the skin.

How to Prevent Hotspots?

You can prevent hotspots from developing on your dog by regularly washing its coat with an antibacterial dog shampoo, preventing ticks and fleas, and ensuring both coat and skin dry completely after swims. All dog breeds can be susceptible to moist eczema, but it more commonly occurs in breeds with a lot of fur.

If your dog loves swimming, it’s even more at risk for developing hotspots. Saltwater can dry out the skin, leading to minor injuries.

The best way to prevent moist eczema is to rinse your dog with fresh water after a swim. It’s essential to ensure your dog is completely dry afterwards so the skin doesn’t remain moist.

Treating Hotspots

Since hotspots itch, you’ll likely notice your dog scratching, biting, and licking the inflamed area, which can lead to further scratches and wounds that allow the infection to spread. It’s crucial to ease the symptoms and prevent your dog from licking and biting the area.

Sometimes, it’s necessary to shave the fur around the affected skin area. This ensures the area gets air and remains dry, naturally reducing the hotspot. Plus, you can better wash the area with a disinfectant shampoo and then apply antiseptic powder.

When to Consult a Vet?

You should consult a veterinarian if:

·         Your dog is in significant discomfort from the moist eczema

·         The eczema spreads to a larger area

·         It begins to smell

·         You find it challenging to treat it at home

The vet will typically shave the fur in the area and thoroughly clean the skin. In some cases, sedatives and pain medication may be necessary during treatment.

You can receive anti-itch cream, pain medication, antiseptic shampoo, and a protective collar to help manage symptoms and prevent the eczema from spreading.

If Hotspots Recurse

If your dog experiences recurring moist eczema, underlying factors may need treatment. Therefore, the dog should be examined by the vet.

Allergy might make your dog’s skin more sensitive, causing more frequent scratching and subsequently small wounds, permitting infection access to the skin.

If the eczema is due to bites from fleas or ticks, preventive treatment against these should be initiated.
