If you've noticed your dog's mouth seems unusually dry or they're having trouble eating, they might be suffering from dry mouth, medically known as xerostomia. This condition, which occurs when dogs don't produce enough saliva, can significantly impact your pet's oral health and overall well-being.
While occasional dry mouth might result from simple dehydration, persistent cases could signal more serious underlying conditions, including autoimmune disorders like Sjögren-like Syndrome. Understanding the causes, recognizing the symptoms, and knowing when to seek veterinary care are crucial for maintaining your dog's health.
Common Causes of Dry Mouth in Dogs
Several factors can lead to dry mouth in dogs:
- Dehydration from insufficient water intake or excessive activity
- Side effects from medications like antihistamines and diuretics
- Autoimmune conditions, particularly Sjögren-like Syndrome
- Radiation therapy affecting the salivary glands
- Nerve damage impacting saliva production
- Systemic diseases such as diabetes or Cushing's disease
Recognizing the Signs of Dry Mouth
Watch for these key indicators of dry mouth in your dog:
- Thick, sticky saliva or complete lack of visible saliva
- Cracked or dry tongue
- Bad breath
- Difficulty eating or swallowing
- Increased plaque buildup

Immediate Care Strategies
The first step in treating dry mouth often involves addressing immediate comfort and hydration:
