Tonsillitis

Tonsillitis is an inflammation of the tonsils in the throat area of the dog, which manifests itself through difficulty swallowing and a gagging reflex. Your dog scratching at its neck, gagging after drinking, and avoiding its favourite dry food are the first warning signs of tonsillitis.

The tonsils sit on the left and right in the back of the throat and normally catch bacteria before they can penetrate deeper into the respiratory system. In cases of tonsillitis, they are swollen, red and painful, just like when you have tonsillitis.

How do I recognise tonsillitis in my dog?

The most noticeable sign: your dog drastically changes its eating behaviour. It approaches the bowl, hesitates, takes a bite and immediately gags or coughs.

Further symptoms that occur together:

• Increased drooling, especially after contact with food
• Scratching at the neck or rubbing the head on the floor
• Gagging noises when drinking
• Avoidance of hard food despite normal interest in soft treats
• Unusual bad breath that does not smell like typical “doggy breath”

A dog with mild tonsillitis often still eats wet food or soft treats, but completely avoids dry food. This distinguishes it from general loss of appetite.

What triggers tonsillitis?

The most common trigger is bacteria that infect the tonsils when the immune system is weakened or following dental inflammation. A typical scenario: your dog had tartar removal or an injury in its mouth a week ago, and now the tonsils become secondarily inflamed.

Viruses such as kennel cough often attack the entire respiratory system, including the tonsils. You can recognise this by the fact that, in addition to difficulty swallowing, coughing and possibly nasal discharge also occur.

Foreign bodies in the throat, a blade of grass hanging between the teeth, a bone fragment, mechanically irritate the tonsils. This form develops quickly over a few hours.

When do I need to go to the vet immediately?

Go on the same day if your dog has not eaten or drunk anything at all for more than 6 hours. Dehydration develops quickly with tonsillitis because swallowing is painful.

Further warning signs:

• Heavy drooling with bloody foam
• Breathing difficulties or wheezing breathing noises
• Swelling of the neck visible from the outside
• Apathy despite interest in the surroundings

In cases of mild symptoms, you can wait 24 hours and observe the development, but only if your dog continues to consume soft food and water.

How is tonsillitis treated?

The vet diagnoses by visually examining the tonsils with a throat mirror. Swollen, red tonsils with whitish deposits confirm the suspected diagnosis.

If the cause is bacterial, antibiotics are used, usually for 7-10 days. Important: Do not stop treatment prematurely, even if the symptoms disappear after 2-3 days.

Anti-inflammatory agents relieve pain and reduce swelling. This allows your dog to swallow normally again before the antibiotics have fully taken effect.

Dietary adjustments support healing: wet food or soaked dry food, lukewarm (not hot) broth. Cold sometimes relieves the pain; try an ice cube or frozen liverwurst.

Can I prevent tonsillitis?

Regular dental checks prevent oral inflammation from spreading to the tonsils. Have tartar removed professionally before inflammatory foci form.

In dogs prone to respiratory infections: avoid contact with coughing conspecifics and ensure good air quality. Cigarette smoke and dusty environments additionally irritate the tonsils.

After foreign body injuries in the mouth, observe your dog for 3-4 days for difficulty swallowing. Early treatment prevents chronic courses.

Can tonsillitis become chronic?

Yes, with incomplete treatment or repeated irritation, some dogs develop chronic tonsillitis with recurring complaints.

Is tonsillitis contagious to other dogs?

Only if caused by viruses, then via droplet infection when barking or coughing. Bacterial forms are usually not contagious.

How long does healing take?

With proper treatment, symptoms disappear after 3–5 days. Complete recovery takes 1–2 weeks.

Can home remedies help with tonsillitis?

Honey (only for adult dogs) can have a soothing effect, but never replaces vet treatment for bacterial infections.

When is tonsil surgery necessary?

Very rarely, only in cases of recurring severe inflammation that does not respond to any treatment. The tonsils serve a protective function and are removed only as a last resort.
