Known Causes of Facial Swelling In dogs

Dental Infection

If your dogs suffer from periodontal disease, they can also be prone to a dental abscess, which often takes place on their back teeth (upper molar teeth) and spreads into their gum, causing pain and facial swelling.

Besides, your dogs will also develop halitosis (a scientific name for bad breath), as well as become afraid to eat or chew their food on the hurting side.

If your dogs show these signs, you should bring them to your local vets to remove the offending tooth, drain the abscess, and heal your dog’s swelling with painkillers and antibiotics.

Penetrating Objects

In the summer, small objects such as grass seeds can penetrate into your dog’s skin on the outside of their faces or from the inside of your eye or mouth. The appearance of unexpected materials may sometimes cause facial swelling in your dogs.

To remove those tiny objects, you will have to take your dogs to professionals who will then do some exploration of the affected area to remove the culprit while keeping your dogs under the influence of the anesthetic. After that, your dogs will be healed with antibiotics and pain relief.

Bite Wound

If your dogs get bitten on the faces by other animals, the bacteria from that bite will penetrate deeply into their skin and multiply, causing infection. When the wound heals, the bacteria will have nowhere to go, leading to the previously bitten areas becoming swollen.

This type of facial swelling is noticeably painful and will make your dogs unable to enjoy their food, thus, causing your dogs to feel unwell.

In this case, the best thing to do is to bring your dogs to your local vet to receive proper treatments, with antibiotics and pain relief being used. Also, you have to keep the swollen area clean with some antiseptic solution prescribed by your vet.

Head Trauma

In some cases, your dogs will bang their heads into hard surfaces like furniture or trees while they are playing, running around, or fighting with other dogs. This will leave bruising which can cause facial swelling on their faces and head areas.

Usually, you can manage these mild bruising and swelling at home without using any types of antibiotics or painkillers. However, it is recommended that you contact your local vet if the swelling happens to be near their eyes, as it can be a sign of further damage.

Reactions To Allergies

Just like cats, dogs are naughty creatures that can sometimes provoke a bear or wasp, and then become the receiving end of their stings. Interestingly, the stings usually take place on the dogs’ mouths, as your companions will most likely bite back at the insects in retaliation for being attacked.

After your dogs are stung by the insects, you may notice them using their paws to ease the pain in their mouths or salivating more frequently.

Finally, there will be an out-of-the-blue onset of facial swelling, which will heal in a short time. However, the swelling will sometimes spread, causing breathing difficulties in some sensitive dogs. If this happens, rush your dogs to your local vet for immediate treatment.


Sometimes, facial swelling inside your dogs’ mouth, nose, or near their eyes can be caused by the development of a tumor. In this case, the tumor can be growing at a rapid rate and an urgent assessment is needed for your local vet to tackle the condition as soon as possible.
