Tonsillitis in Dogs: Causes, Symptoms, and Treatment Recognizing Canine Tonsillitis and Treating It

Tonsillitis in Dogs: Causes, Symptoms, and Treatment

Tonsillitis, or tonsil inflammation, is a common health problem in dogs. Learn about this condition further in this article.

Do dogs have tonsils?

Yes, dogs have tonsils. However, tonsillitis, an inflammation of the tonsils, is a common health condition in dogs. Just like humans, dogs can experience throat pain, difficulty swallowing, and other symptoms associated with this condition. Many conditions, including bacterial or viral infections, allergies, or other underlying medical conditions, can lead to canine tonsillitis.

This article will discuss the causes, signs, diagnosis, and available treatments for dog tonsillitis as well as some advice for keeping your pet buddy well.


There are several potential causes of tonsillitis in dogs; some include:

  • Bacterial infections: One of the most typical causes of canine tonsillitis is bacterial infections. The common bacteria Streptococcus, Staphylococcus, and Bordetella can cause tonsillitis.

  • Viral infections: Like humans, dogs can also develop tonsillitis as a result of viral infections. Viruses that can cause tonsillitis in dogs include parainfluenza, adenovirus, and herpesvirus.

  • Allergies: In certain dogs, allergic responses to pollen, dust, or other environmental allergens can result in tonsillitis.

  • Immune system issues: Certain immune system issues, such as autoimmune illnesses, can result in chronic tonsillitis.

  • Obstruction: Obstruction of the airway due to a foreign object or tumor can cause tonsil stones in dogs.

  • Dental disease: Dental diseases, like periodontal disease, can lead to tonsillitis in dogs.

Can Dogs Get Strep Throat?

Yes, dogs can get strep throat, but it is relatively rare. Tonsillitis in dogs is frequently brought on by streptococcal bacteria, which can occasionally result in a condition resembling strep throat in people. It's crucial to remember that different strains of streptococcal bacteria affect humans and dogs and that strep throat symptoms in dogs may vary from those in humans.

Strep throat in dogs may present with symptoms such as difficulty swallowing, fever, coughing, and lethargy. If you suspect your dog has strep throat or any other respiratory illness, it's vital to seek veterinary care promptly to ensure they receive appropriate treatment.


Depending on the extent of the inflammation and the underlying reason, the signs of tonsillitis in dogs might change. Nonetheless, some typical symptoms to watch out for are as follows:

  • Trouble swallowing: Tonsillitis in dogs can cause difficulty swallowing, which can lead to decreased appetite and weight loss.

  • Excessive drooling: Tonsil irritation may be indicated by excessive drooling or drooling that is accompanied by blood.

  • Bad breath: Tonsillitis can cause bad breath, which is often a sign of bacterial infection.

  • Coughing: Tonsillitis in dogs can cause a chronic cough, especially if the infection progresses to the trachea and throat.

  • Fever: A fever is a typical sign of canine tonsillitis and may signify a deeper illness.

  • Lethargy: Dogs with tonsillitis may appear lethargic or less active than usual.

  • Swollen lymph nodes: Swollen throat in dogs can be a sign of tonsillitis.

  • Red, inflamed tonsils: Tonsillitis may be present if you observe that your dog's tonsils are red and inflamed.

Treatment and Management

The underlying cause and degree of inflammation will determine the course of treatment for canine tonsillitis. Typical forms of treatment and management include:

  • Antibiotics: If the tonsillitis is caused by a bacterial infection, antibiotics may be prescribed to help clear up the infection.

  • Anti-inflammatory medications: Anti-inflammatory medications such as Prednisolone and Meloxidyl may be prescribed to reduce inflammation.

  • Pain management: Dogs with tonsillitis may experience agony and discomfort, so pain medications may be prescribed to manage their condition.

  • IV fluids: To prevent dehydration in dogs with severe tonsillitis, IV fluids may need to be administered while they are hospitalized.

  • Surgery to remove the tonsils: If the inflammation is prolonged or the tonsils are obstructing the airway, surgery to remove the tonsils may occasionally be required.

  • Treatment of underlying conditions: If an underlying medical problem, such as allergies or dental disease, contributed to tonsillitis, that issue may need to be managed in order to stop future cases of tonsillitis.

Can You Prevent Canine Tonsillitis?

While tonsillitis in dogs may not always be preventable, there are several measures you can take to assist in lowering the likelihood that your dog may become ill with this condition:

  • Practice good oral hygiene: Brush your dog's teeth regularly and provide dental chews or toys to help keep their teeth and gums healthy.

  • Ensure that your dog receives the necessary vaccinations: Immunizations can aid in defending your dog against viral illnesses that might cause tonsillitis.

  • Keep your dog away from diseased animals: While at all possible, stay away from sick animals as bacterial and viral infections can transfer rapidly between animals.

  • Minimize exposure to environmental allergens: If your dog has a history of allergies, you should try to limit its exposure to dust, pollen, and other environmental allergens to help avoid tonsillitis.

  • Feed a healthy, balanced diet: A healthy, balanced diet can help support your dog's immune system and general health.

  • Routine veterinary check-ups: Frequent check-ups with your veterinarian can help catch and treat underlying health conditions before they lead to tonsillitis or other complications.

You may lower the likelihood that your dog will contract tonsillitis and other illnesses by adopting these preventative actions and paying close attention to your dog's health.
