Although the name suggests otherwise, ringworm is not caused by a worm at all-but a fungus. This highly contagious infection can lead to patchy areas of hair loss on a dog, and can spread to other animals-and to humans, too.
Common Causes and Treatments of Dog Facial Swelling
Facial swelling in dogs can be life-threatening if the swelling progresses to the throat, so don't try to diagnose the cause of your dog's swelling yourself. If your pet's face looks swollen, or lopsided, get your dog to a veterinarian immediately.
Some common causes of facial swelling in dogs include:
Often caused by animal bites or other wounds, head and neck abscesses show up suddenly, usually accompanied by a fever, and can leave a lopsided look to your dog's head or neck. These are extremely painful; if your dog has facial swelling and is refusing to eat or drink, an abscess could be the cause.
It's important for abscesses to be treated right away. Treatment may include surgical drainage and antibiotics.
Infected or fractured teeth and untreated gum disease can also lead to abscesses, accompanied by facial swelling, fever, depression, and great pain for your dog.
Treatment for dental abscesses may include removing the infected tooth along with a course of antibiotics.
Tumors (Noncancerous and Cancerous)
Mouth and throat tumors can occur in dogs and, along with facial swelling, symptoms may include problems eating, bleeding, and excessive odor. Dogs can also get tumors associated with the eye socket, which can make the eye bulge.
