Facial Swelling In Dogs

Facial Swelling In Dogs

If you see that your dog's face is swelling, then it's likely to be caused by another underlying health complication. Today our Ypsilanti vets illuminate what serious conditions facial swelling can be a sign of in dogs.

Causes Of Facial Swelling In Dogs

A large number of things can be behind facial swelling in dogs, but it is almost always a sign 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

Usually, allergies are behind facial swelling in your canine companion. 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. Swelling may be especially noticeable on the muzzle and eyelids, reddened skin, and they may be exhibit behavior suggesting that your pet is itchy and uncomfortable if they are experiencing an allergic reaction.

Facial Swelling And Dental Problems 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.


Facial swelling can be caused by benign (non-spreading) or malignant (spreading or growing) tumors 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.
