Payotraumatic Dermatitis is very common in hot and humid weather especially in dogs with thick and long hair coats.Hot Spot in Dogs (Pyotraumatic Dermatitis, Moist Dermatitis) Symptoms, Diagnosis and Treatments
Anything that initiates an itch-scratch cycle can predispose a dog to developing Payotraumatic Dermatitis In most cases, the exact cause is unknown, although Payotraumatic Dermatitis are often caused or exacerbated by self-trauma due to an underlying factor such as fleas, mites, lice, ticks, bacteria, fungi, ear infections, allergies, anal sacculitis or topical irritants. In some cases, a severe essential fatty acid deficiency may be a contributing factor. Hot spots typically are exacerbated by licking, biting, rubbing and scratching.

Hot spots often occur after a dog has been swimming. Dogs that are prone to allergies also tend to get hot spots more readily than non-allergic dogs. Certain breeds are over-represented, including Golden Retrievers, Rottweilers, Saint Bernards and German Shepherds, although these breeds tend to develop a deeper bacterial dermatitis on the face or cheek region without obvious evidence of self-trauma.

Here is other underlying problems associated with Hot Spots :
Otitis externa, Ectoparasites, Ocular disease, Food hypersensitivity, Contact dermatitis, Atopic dermatitis and Anal sac disease.

Symptoms and Diagnosis :
There is two different kinds of Payotraumatic Dermatitis :Hot Spot in Dogs (Pyotraumatic Dermatitis, Moist Dermatitis) Symptoms, Diagnosis and Treatments

Superficial hot spots:
Superficial hot spots are, as the name implies, on the skin surface and appear as a moist patches of inflamed, ulcerated, itchy skin with matted hair.

Deep hot spots:
this kind is quite different from the superficial form in that there is itchiness, Hot Spot in Dogs (Pyotraumatic Dermatitis, Moist Dermatitis) Symptoms, Diagnosis and Treatmentsulceration, and inflammation but also a very deep infection and oozing.

Affected animals typically lick or scratch persistently at an area of skin. The periaural and the dorsal and dorsolateral lumbosacral regions are commonly affected. The skin is erythematous and moist may be exudative. Alopecia or thinning of the hair may be evident later on in the condition.

Clipping the haircoat allows visualization of the extend of the lesion and identification of the satellite lesions associated with pyotraumatic folliculitis.

Please note that underlying problems should be investigated as the cause for these lesions.



Management and Treatments :
As we mentioned above there is two different kinds of Hot Spots , the required treatment for these two are different ,

Superfacial Hot Spots :
They are easily treated by clipping back the hair from the affected area, then cleansing with a medicated soap and water, followed by application of an appropriate topical medication.

Deep Hot Spots :
Unlike the superficial kind of hot spot, these hot spots must be treated with antibiotics as well as topical treatment. They are seen most often in young dogs and in Golden Retrievers and Saint Bernards.

Sometimes hot spots can be painful, so sedation or anesthesia may be necessary in order to shave and clean the spot properly. Your veterinarian may need to perform cytology or culture the hot spot, to determine the best antibiotic to use during the treatment phase.
Treatment may involve antibiotics (topical and/or systemic, either oral or injectable); anti-inflammatory drugs (NSAIDs); glucocorticoids (steroids to reduce itchiness, pain, and swelling); topical medications; or e-collars or similar collars to prevent your pet from bothering the infected area.

Differential Diagnosis :
Superfacial burn, clipping or grooming, flea bite hypersensitivity, atopic dermatitis, calsinosis cutis, irritant contact dermatitis, deep folliculitis and furunculosis, food allergy, demodicosis, dermatophytosis, anal sac disease.

Prevention :
Prevention is difficult, if not impossible, unless an underlying cause can be determined. If you cannot determine the cause, there are some things you can do to lessen the probability of your dog getting hot spots. For example, giving medicated bathes (e.g.benzoyl peroxide shampoos ) on a regular basis may help prevent some cases from re-occurring. Supplementing the diet with an essential fatty acid supplement may prove helpful in others. Early detection of hot spots before they become serious is also an important part of any preventative program.
