Purulent dermatitis is a common dermatological problem in veterinary offices. Often their occurrence is associated with the season (increase in temperature and humidity) or damage to the epidermis resulting from seborrhea or self-injury caused by itching. They result from the excessive multiplication of bacteria that are components of the physiological biota of the skin.
Long-haired and dense-coated dogs (Labradors, Golden Retrievers, German Shepherds, Cocker Spaniels) are the most susceptible to acute exuding dermatitis. The main cause of hotspots is the already mentioned humidity, but it can also be caused by allergic reactions (e.g. to parasites).
The first symptom that appears when such a problem occurs is skin erythema, followed by itching, which leads to licking and scratching the inflamed area. Licking also produces exudate, the area’s fur is sticky, and the bacterial contaminated area may also smell bad. Swelling caused by inflammation of the hair follicle can also join these symptoms. Such damaged skin is a very painful place that causes discomfort.
The hot spot gives very characteristic clinical symptoms, thanks to which an accurate diagnosis of the problem should not be difficult.
