Have you ever noticed your dog drooling one side of its mouth? This common symptom can be alarming, but it’s important to understand the possible causes and what you can do to help your furry friend. In this article, we’ll explore the reasons behind one-sided drooling in dogs and provide tips on how to address this issue.

Drooling is a natural behavior for dogs, as it helps them cool down, clean their faces, and express excitement. However, when a dog starts to drool excessively on one side of its mouth, it could indicate an underlying health problem. Here are some of the most common causes:

1. Dental Issues

One of the most common reasons for one-sided drooling is dental problems. Tooth decay, gum disease, or a broken tooth can cause pain, leading to discomfort and an increased salivation on one side of the mouth. Regular dental check-ups and proper dental care can help prevent these issues.

2. Nerve Damage

Nerve damage, often caused by a head injury or a condition like a stroke, can disrupt the normal function of the facial nerves, resulting in one-sided drooling. If you suspect nerve damage, it’s crucial to seek veterinary care immediately.

3. Ear Infection

An ear infection can cause pain and discomfort, leading to one-sided drooling. The affected ear may also have a foul odor or discharge. Cleaning the ear and treating the infection can help alleviate the symptoms.

4. Tumors

Although less common, tumors in the mouth, head, or neck can cause one-sided drooling. These tumors may be benign or malignant and require veterinary attention for diagnosis and treatment.

5. Temporomandibular Joint (TMJ) Disorder

TMJ disorder is a condition that affects the jaw joint, causing pain and difficulty in opening and closing the mouth. This can lead to one-sided drooling. Your veterinarian can provide a diagnosis and treatment plan for TMJ disorder.
