Why Swelling in the Face Occurs in DogsSwelling in the face of a dog is not normal and needs to be addressed. If your dog is swelling in the face, jaw area, or any part of his body, immediately make an appointment with your veterinarian. Reasons for facial swelling may include: Allergies If your dog has allergies, he may have swelling in the face. If you know your dog has allergies and is not taking medications, perhaps a visit to the veterinarian can help. If your dog has sudden facial swelling after being outside or in a different location than normal, take your dog to the veterinarian immediately. They may be having an allergic reaction to e.g. a wasp sting. Trauma An incident such as a dog fight or being hit in the face with force will inevitably result in bruising and swelling. Sometimes, the injury doesn't look too bad on the surface but there is significant damage underneath the skin. Poisoning If your dog has been outside or eaten any indoor toxins, such as a poisonous plant, he may have swelling occur in his face. Certain toxic plants that contain oxalates can cause immediate swelling, as well as other symptoms of toxicity.  Tooth or Gum Infections An abscess in the tooth root can cause painful swelling on one side of the face. A gum infection can also cause facial swelling. Your dog will more than likely show signs of pain and may have difficulty eating as well. Tumor If your dog has a tumor, it may be the source of the swelling. Typically, tumors appear over time and not suddenly, so it is careful to always be aware of your dog’s body and face. If you notice your dog’s face is swelling over time, contact your veterinarian. Lymph Node Swelling  Swelling of the lymph nodes can occur due to infections or cancers can cause swelling of the face or neck area. Swelling can be on one or both sides, depending on the cause. Your dog may be fatigued or listless or have other symptoms of illness with the lymph node infection.Salivary mucoceleA collection of saliva that leaks from a damaged salivary gland can cause significant swelling.What to do if your Dog is Swelling in the FaceObserve where your dog is swelling in his face. You may notice his face is swelling all over or only on one side. Call your veterinarian immediately, as sudden face swelling can be a sign of something serious, such as a toxicity or bite from a snake or insect.  Once you arrive at your veterinarian’s office, he will take a closer look at your dog’s face. He will immediately treat him if he finds a bite or sting, or if your dog looks as if he is having a severe allergic reaction. Once your dog is stable, your veterinarian will ask questions about what you suspect caused it, such as if you were outside with him and noticed he was bitten or stung.  Your veterinarian will want to know if your companion has ingested any plants or other toxic substances in your home. Once he gathers all of the information possible, he may then perform a few baseline tests. These tests will include blood work, a biochemistry profile, a skin test, and a possible urinalysis. Once your veterinarian finds what has caused your dog’s face to swell, he will give you the treatment options that are the best for your companion. Of course, this will depend on the diagnosis and the severity of his condition. He may also keep him overnight to give him fluids and to keep him stable, especially if he is having an allergic reaction to something harsh.Prevention of Swelling in the FaceTo prevent insect bites, try your best to monitor your dog while he is outdoors. This can also prevent him from getting into plants that are poisonous. Also, if you have plants that are toxic, have the plants removed from your property or from your home. Some of the prettiest houseplants can be very poisonous, so be sure to check with your veterinarian on the types of poisonous plants before you purchase them.  Do not allow your dog to roam in environments where there is a large amount of insects or where there could be snakes, as a snakebite can be lethal to your companion. For allergies, try to keep the allergens to a minimum in his environment, or speak to your veterinarian about allergy medication if he has a severe case.Swelling in the face can be expensive to treat.
