Causes of Face Swelling in Dogs
The potential causes of facial swelling in dogs are numerous and varied. Since a swollen face is often a harbinger of further underlying health problems it is common for dogs with facial swelling to present other symptoms like lethargy and loss of appetite.
Allergic Reaction
The most typical cause of facial swelling in dogs is an allergic reaction. Bug bites, bee stings, vaccinations, medications, certain foods, toxin exposure, and pollen are just some of the many potential allergens that could be affecting your dog if they are presenting a swollen face. Mild reactions tend to improve with minimal intervention, but severe reactions are an emergency that demands immediate veterinary attention.
Allergies result in an inflammatory response that can cause hives and swelling, on a dog's face. You may especially notice swelling of the muzzle and eyelids, reddened skin, or behavior that suggests your canine companion is itchy and uncomfortable if they are experiencing an allergic reaction.
Dental Problems and Facial Swelling in Dogs
Face swelling in dogs can be the result of dental health issues. Tooth abscesses and other dental infections can go deep beneath the gums and cause a pocket to fill with pus, which in turn causes facial swelling. Broken teeth, oral injuries, and periodontal disease are all potential causes of facial swelling in dogs as well.
Traumatic Injury
Trauma is capable of causing swelling in dogs just as much as it is in people. Whether from a fall or the bite of another animal, a facial injury is as likely an explanation as any for a swollen face in your dog.
Tumors
Tumors both benign and malignant causes facial swelling whilst growing on a dog's face or head. Tumors can cause pressure and pain, and furthermore are possibly a sign of cancer - if you suspect your dog may have a tumor on their face we strongly suggest contacting your vet as soon as possible. As well as tumors, cysts can grow large on your pet's face and be confused for swelling. Cysts are fluid-filled growths that are most often benign and only require attention if they grow to an unignorable size.
