Common causes of facial swelling in dogs include allergies, abscesses, dental and oral infections, tumors, parasitic infestation and congestive heart failure.
Dogs react adversely to a variety of substances, and one of the signs that a pooch has come in contact with a substance that its body doesn’t react well with, is swelling of the face.
That said, some of the substances that are commonly responsible for triggering allergic reactions in dogs include food, chemicals, medication, insect bites or plant materials like pollen.
In some cases, swelling of a dog’s face, along with discoloration of the gums and fainting can be an indicator that the pooch is suffering from a severe allergic reaction that’s causing a blockage in the canine’s windpipe; This, in turn, results in breathing difficulties, and immediate medical attention is needed to keep such a pooch alive and healthy.
Dog abscesses are characterized by the collection of pus within a swollen region on the pooch’s face. And if you observe a loss of appetite in your pooch, coupled with characteristic face swelling, then such a dog is most likely suffering from an abscess of the head or neck.
Abscesses in dogs develop due to several reasons, but some of the most common causes include bites from insects or other animals, trauma from an injury or bacteria attacks.
Dental And Oral Infections
Dogs are prone to developing several dental and oral infections, and these tend to cause the infected pooch’s face to swell. A broken or fractured tooth, tooth root abscesses and gum diseases are some of the common dental problems that most dogs are predisposed to.
And along with the swelling of the face, dental infections are also very painful for dogs, and they usually cause high fever, loss of appetite, and subsequent weight loss.
Similarly, the swelling of a dog’s salivary glands can also trigger a corresponding swelling in the dog’s face.
Tumors can develop anywhere on a dog’s body, but they all have one thing in common – they cause swelling; Hence, the swelling of a dog’s face may also mean that a tumor is growing on such a pooch’s face.
There are several reasons for growth of tumors on dogs, but some of the most common include cancer, hormonal imbalances, exposure to chemicals, and in some cases, genetics.
Dogs are susceptible to several parasites, and a swollen face may be telling you that a pooch is under attack from either tapeworms, hookworms, roundworms or whipworms.
The aforementioned parasites typically attack a dog’s intestines, but the presence of external parasites such as fleas, ticks and lice can also induce swelling of a pooch’s face.
Congestive Heart Failure
The facial swelling of a dog can also be an indicator of a highly serious health condition such as congestive heart failure.
Dogs suffering from a congestive heart failure typically experience inappropriate and excessive fluid build-up in the tissues surrounding the heart; The excess fluid, in turn, infiltrates surrounding tissues, and eventually makes its way up to the dog’s face, where it causes swelling.
How Does A Dog With A Swollen Face Look?
The first and immediately noticeable sign that a dog’s face is swollen is a distortion of the doggie’s facial shape. And along with this distortion, you will also notice signs such as:
- Swelling of the eye region – this may lead to the pooch not being able to close its eyes well
- A swollen muzzle
- Swelling of the jaw and throat area
- Bumps or hives on the dog’s face
A dog with a swollen face may also be itchy, depending on what is responsible for the swelling.
