* Allergies: Corgis can develop allergies to various substances, such as pollen, dust mites, or food ingredients. Allergies can cause eye inflammation, itching, and discharge.
* Bacterial infections: Bacteria can enter the eye through a scratch or other injury, causing an infection. Bacterial conjunctivitis is characterized by red, swollen eyes with thick, yellow-green discharge.
* Viral infections: Viruses, such as canine distemper or adenovirus, can also cause eye inflammation. Viral conjunctivitis is often accompanied by other symptoms, such as fever, coughing, and sneezing.
* Dry eye (keratoconjunctivitis sicca): This condition occurs when the tear glands do not produce enough tears, which can lead to eye inflammation and damage to the cornea (the clear outer layer of the eye).
* Foreign objects: A foreign object, such as a piece of dirt or a blade of grass, can become lodged in the eye and cause irritation and inflammation.
Causes of medium-sized bumps on the muzzle of a 7-month-old Pembroke Welsh Corgi:
* Puppy acne: This is a common skin condition that affects puppies, characterized by small, red, or white bumps that appear on the chin, muzzle, and around the eyes. Puppy acne usually resolves on its own within a few months.
* Bacterial infections: Bacterial infections can also cause skin bumps on the muzzle. Staph and MRSA are two of the most common types of bacteria involved in the cause of these infections.
* Fungal infections: Fungal infections, such as ringworm, can also cause skin bumps on the muzzle.
* Skin allergies: Allergies to food, environmental allergens, or flea bites can cause itchy, inflamed skin and the development of bumps.
* Pemphigus foliaceus: This is a rare autoimmune skin disease that affects Corgis and other breeds. It causes large, crusty skin lesions that often start on the face and then spread to other parts of the body.
If your 7-month-old Pembroke Welsh Corgi has eye inflammation or skin bumps on the muzzle, it is important to take them to the vet for a diagnosis and appropriate treatment.
