Salivary gland and perisalivary swelling in dogs refers to a visible or palpable enlargement of the glands in the oral region, which can be triggered by various factors, including infections, injuries, or other pathological conditions.

Can Occur with the Following Diseases:

Basics and possible causes

The salivary glands of dogs are responsible for the production and release of saliva, which plays an important role in digestion and oral hygiene. There are several salivary glands, including the parotid, mandibular, sublingual, and zygomatic glands. Swelling in these areas may indicate an inflammatory condition, also known as sialadenitis, or the formation of a salivary cyst, known as a salivary mucocele.

One of the most common causes of salivary gland swelling is an infection, which can be bacterial or viral in nature. Bacterial infections often arise as a result of injuries that allow bacteria to enter the glands and cause inflammation. Viral causes are less common but can be triggered by certain systemic infections.

Traumatic injuries from bites, impacts, or other accidents can also lead to swelling. These injuries cause tissue damage that triggers an inflammatory reaction, leading to swelling of the affected gland.

Another cause can be the formation of a salivary mucocele, which occurs when saliva leaks from the gland and accumulates in the surrounding tissues. This leads to a fluid-filled swelling that can be painful depending on its size and location.

In rare cases, tumors or systemic diseases such as autoimmune disorders can also affect the salivary glands and cause swelling. These require a more comprehensive diagnostic evaluation and treatment.

Typical accompanying symptoms

  • Swelling in the area of the jaw or neck: A visible or palpable enlargement in these regions may indicate an affected salivary gland.

  • Pain or discomfort when eating: Dogs may show difficulty or pain when chewing, which indicates painful swelling.

  • Salivation (Hypersalivation): Excessive saliva production may occur along with the swelling.

  • Difficulty swallowing: The swelling can constrict the throat and make swallowing difficult.

  • Fever and general lethargy: These systemic symptoms may indicate an infection that requires medical treatment.

  • Bad breath: Infections or saliva accumulation can lead to bad breath.

When to visit the vet?

A veterinarian should be consulted if the swelling increases rapidly, is very painful, or if the dog shows other symptoms such as fever, loss of appetite, or lethargy. These signs indicate that a serious infection or other serious condition may be present that requires immediate medical treatment.

Even if the swelling does not subside or worsens after a few days, a visit to the veterinarian is necessary. Early diagnosis can help identify and effectively treat the underlying cause before complications arise.

If the dog has difficulty breathing or shows signs of choking, an emergency veterinarian should be consulted immediately, as this may indicate severe swelling or a possible blockage of the airways.

Symptom recognition for animal owners and veterinary diagnostic procedures

It is important for pet owners to regularly examine their dog’s head and neck area and pay attention to swelling, pain, or other unusual changes. Careful observation of behavior, especially when eating and drinking, can also provide clues to problems.

The veterinarian will usually begin with a thorough clinical examination to assess the affected region. He will palpate the area to assess the size, consistency, and tenderness of the swelling. Depending on the suspicion, blood tests can be carried out to confirm infections or inflammatory conditions.

Imaging techniques such as ultrasound or X-rays can be used to more accurately locate and evaluate the swelling. These methods help to better understand the cause of the swelling, especially if a salivary mucocele or a tumor is suspected.

In some cases, a fine needle aspiration or biopsy may be necessary to take samples from the affected gland. These samples are then analyzed in the laboratory to make an accurate diagnosis and determine the best possible treatment strategy.

What can pet owners do and professional therapy options

Until the veterinarian visit, pet owners can try to relieve their dog’s symptoms. Gently cooling the affected region with a cloth soaked in cold water can help reduce swelling and pain. However, it is important to be careful and not apply ice packs directly to the skin to avoid frostbite.

The dog should be kept as calm as possible to avoid stress and further injury. Stress can worsen the symptoms and should therefore be minimized. In addition, the dog should receive soft food to make chewing easier and avoid pain.

It is important not to allow the dog access to hard or sharp objects that could worsen the swelling or further injure the glands. Playing with other dogs should also be avoided to prevent further trauma.

Pet owners should not administer any medication without consulting the veterinarian, as this could worsen the symptoms or make diagnosis more difficult. It is crucial to follow the veterinarian’s instructions carefully and to consider an immediate re-consultation in the event of ambiguities or deterioration of the condition.

Outlook on current research

Salivary gland and perisalivary swelling in dogs is a symptom that is receiving increasing attention in veterinary medical research. Scientists are investigating various mechanisms and causes that can lead to this type of swelling. It is believed that inflammatory conditions caused by bacterial or viral infections may play a role. Current studies are focused on identifying specific pathogens that trigger such inflammatory conditions in order to develop more targeted treatment strategies.

Another branch of research is investigating genetic predispositions. Some dog breeds may be genetically more susceptible to salivary gland swelling. By mapping genes associated with susceptibility to certain diseases, scientists hope to develop preventive measures. In the long term, this research could lead to the development of selective breeding programs to minimize the risk of such symptoms in future generations.

The role of the immune system in the development of salivary gland swelling is another significant area of research. Abnormalities in the immune response could cause the body’s own defense system to attack the salivary glands, leading to swelling and inflammation. By studying the immune response in affected dogs, researchers are trying to develop immunotherapies that can correct this malfunction.

There is also progress in diagnostics. New imaging techniques, including high-resolution ultrasound and MRI techniques, allow for a more accurate assessment of swelling. These technologies help veterinarians to better determine the severity and exact location of the swelling, leading to more precise diagnoses and targeted treatment approaches.

The development of new pharmacological treatments is also a focus. Researchers are working on drugs that specifically have an anti-inflammatory effect without the side effects of traditional corticosteroids. These new drugs could be of great benefit to dogs with chronic or recurrent salivary gland swelling.

In preventive research, nutrition and lifestyle are being investigated as potential factors. Some studies suggest that certain diets can reduce the risk of salivary gland swelling. Exploring the role of dietary supplements and specific diet plans could contribute to the development of prevention strategies that mitigate the occurrence of such symptoms.

Collaboration between veterinary and human physicians is also an emerging field. Since similar symptoms also occur in humans, the exchange of knowledge and research results could offer new insights into the treatment of salivary gland swelling in dogs. This interdisciplinary collaboration could lead to the development of new, more effective treatment protocols.

Another interesting aspect of the research is the investigation of the effects of environmental factors. Various environmental toxins or irritants could potentially cause or worsen swelling. By identifying these environmental influences, preventive measures could be developed to protect affected dogs from such factors.

In addition, the role of stress and psychological well-being in the development of salivary gland swelling is being investigated. There is evidence that stress can impair immune function, which in turn increases susceptibility to inflammatory conditions. Exploring these connections could lead to holistic treatment approaches that consider both physical and psychological aspects.

Finally, long-term monitoring of dogs with recurrent salivary gland swelling is considered important to improve understanding of the course of the disease and the long-term effectiveness of treatments. Such studies could provide valuable data that contribute to the optimization of future therapies.
