Acute Moist Dermatitis: Hot Spots in Dogs
Summer heat may predispose to hotspots
Hot Spots in Dogs
Your dog was doing well and was acting playful one second, and the next thing you know, he starts scratching at an area and within seconds, chunks of hair start flying everywhere. Alarmed, you look at the area and find a pretty large red, inflamed, hairless area. Within a short time, aggravated by the dog's licking and possibly, scratching, the area gets weepy with a yellow discharge. Your dog yelps in pain as you touch the area and you realize it must really burn for your dog to react that way. Concerned, you take your dog to your veterinarian wondering what kind of malady must be affecting him this time!
What are Hot Spots and What Can Be Causing Them
If your dog just experiences something similar as described above and the picture appears familiar, chances are high your dog may be suffering from a hot spot. Hot spots, medically known as ''Acute Moist Dermatitis'' are generally patches ranging in size between one to four inches. They often are characterized by a yellowish exudate that may emanate a foul odor. They tend to occur just about anywhere on the dog's body but they are most commonly found under the ear flaps and on the neck.
Dogs most commonly affected are those with longer coats due to the likeliness of trapping moisture. Hot spots can also develop underneath hair mats or hair that is shedding but still clinging on the dog's coat. They can be caused by a variety of factors including but not limited to:
- Food allergies
- Flea infestations
- Skin parasites
- Insect bites
- Summer heat
- Presence of burrs
- Leaving a wet collar on
- Not drying dog after a bath or swim
- Poor grooming
As seen, there are many predisposing factors that make the warmer months more at risk for hot spots. In the spring/summer time dogs shed more, they are exposed to burrs, and are more likely to be under the summer heat. Pesky parasites are around more and insect bites are not uncommon. Dogs are also most likely to swim in water or get bathed without being dried well, trapping moisture and bacteria.

How Hot Spots are Diagnosed and Treated
Your vet may want to collect a sample in order to rule out any fungal or yeast infections as these may require a different course of treatment.
Because hot spots are painful, sometimes dogs need to be sedated for treatment. The first step is to trim the area of all hair in order to let the hot spot dry and heal. A good pair of clippers for dogs will do the job. The veterinarian will often prescribe a Betadine or a chlorexidine shampoo like Nolvasan to dry up the area.
To prevent aggravating the area, an Elizabethan collar is often recommended. Dogs are often put on cortisone-like drugs and antibiotics to speed up the healing process.
