Pimples on dog’s head are a common phenomenon in the classification of dermatological diseases. Pimples (acne) most often develop in young adults and puppies. The pathological process often begins with the appearance of edematous areas of red-purple color, and then seals in the hair follicles develop which are externally similar to acne. Bacteria, getting into the cavity of the follicle, multiply there, filling it with purulent contents.
Mild acne usually does not cause severe discomfort, while the severe form of the disease, when lesions cover large areas of the epidermis, can be very painful for the dog. It is important for the owner of the animal to recognize the first symptoms of the disease in time to take appropriate urgent measures, because the delay in treatment is fraught with serious consequences.
Several varieties of pimples are found in dogs: in form they resemble white bumps or red-brown color, towering above the skin level. The appearance of white pimples on dogs’ head is due to the presence of pus. Any rash on the skin of the animal is a consequence of the inflammation process. Such phenomena rarely disappear by their own, often they are accompanied by discomfort and itching, which eventually leads to combing and licking the affected areas, and this is dangerous because of the spread of infection. Most often, rashes are observed on the face, especially the lips and on the chin, under the neck, in the places where it comes into contact with the collar, in skin folds, lower abdomen, back, inguinal region, rarely on the tail. In the absence of treatment, rashes can lead to the spread of eczema and inflammation of the deeper layers of the skin.
The Main Causes
According to veterinarians, the primary cause is considered to be hormonal changes as hard pimples on dog’s head are most common among puppies and young growing animals.
In the age of 5-6 months the baby-puppy becomes a teenager. For this reason, changes of the hormonal system occur in the younger pet. Pimples can be found on the head, ears, chin and muzzle. They do not cause any inconvenience to the animal and disappear on their own as they grow up. Pimples in the puppy’s groin can be caused by contact dermatitis, for example, contact with wet litter. They are similar to the baby’s sweating. Carelessness of the owner, ignoring the rules of hygiene can also be a provoking factor in the development of acne.
One of the most common typical causes of acne on the head in dogs is a special structure of the skin, forming folds. In such breeds as Shar Pei, bulldog, Mastiff and pug rashes are formed in the skin folds, which leads to the reproduction of bacteria that cause rashes. Pimples can appear under the collar, as the skin sweats under it and does not receive enough oxygen. This provokes the development of microorganisms. The genital area is also a breeding ground for bacteria that cause irritation, itching and pimple formation. The causes of acne can be serious diseases:
- Mange (demodicosis), ringworm (dermatophytes).
Long-term observations have shown that the appearance of a rash most often occur to dogs prone to allergies. Itching and rash are the primary symptoms of allergy, but other possible causes should not be ignored.
Pyoderma is a disease caused by the bacteria Staphylococcus intermedius, which poses a threat to the health of the animal. The disease is caused by the pathogenic effects of staphylococcal and streptococcal microorganisms. The animal becomes sluggish, restless, appetite decreases. In addition to the main symptoms, purulent rashes appear on the lips, nose and genitals. Pyoderma refers to immunodeficiency diseases, formed under the influence of negative or aggressive environmental factors, unbalanced diet and improper exercise.
Demodicosis or scabies is not a contagious disease, but manifests itself as a hereditary pathology. You should not postpone the treatment, as the progressive disease causes baldness. First appear small pimples on top of dog’s head appear, then the lesions are localized on the chin, ears and lips, then all over the body. Lesions cause hard itching and bring discomfort and anxiety to the animal.
Dermatophytosis (ringworm) – a disease caused by fungal microorganisms. In the beginning of the course it is manifested by the presence of small pimples. It is difficult to differentiate the disease at once. In case of untimely therapy, baldness is possible.
A rash on the body of dogs can be caused by allergies. It is provoked by various factors:
- food and nutrition (food allergens);
- pollen allergens;
- household chemicals and environmental hazards;
- bites of fleas, wasps, mosquitoes.
Allergic rash is manifested in the form of small pimples, they itch and bother a dog.
How to Prevent the Disease?
Keeping the head and muzzle of a young animal clean and dry can prevent the development of the disease. Careful care and hygiene of the front part are especially necessary for breeds with deep folds, such as mastiffs, pugs, boxers, bulldogs. Caring and attentive attitude to your pet is the main prevention against the disease.
When pimples appear on the animal it is necessary to apply to a vet. He/she can identify the cause of the disease – whether it is caused by hormonal changes or is a consequence of infectious processes or allergies.
