How to Tell If a Dog Is Crying: Understanding Canine Emotions and Eye Health
While dogs are well-known for being emotionally expressive companions, their ways of showing feelings differ significantly from those of humans. One frequently asked question is:
Can dogs cry like humans? The answer lies in distinguishing emotional expressions from physiological reactions.
Do Dogs Shed Emotional Tears?
Unlike humans, who produce tears as a result of emotional arousal,
dogs do not shed emotional tears in the same way. Though dogs can have teary eyes, these are typically due to
physical causes rather than sadness.
Recent research, such as the 2022 study published in Current Biology, suggests that dogs may produce slightly more tears during emotional reunions with their owners. This was measured using the Schirmer tear test, indicating a
possible link between oxytocin (the bonding hormone) and tear production. However, scientists emphasize that more data is needed to determine if these tears are truly emotional.
Common Causes of Watery Eyes in Dogs
Veterinary experts agree that most instances of dog tears are due to
medical or environmental reasons. These include:
- Irritants like dust, pollen, or foreign materials
- Allergies to substances or foods
- Blocked tear ducts from genetics, inflammation, or infection
- Eye infections caused by bacteria, viruses, or fungi
- Eye injuries such as scratches to the cornea
- Chronic diseases like glaucoma, dry eye, or ingrown eyelashes
These issues are especially common in
brachycephalic breeds, such as Bulldogs and Pugs, due to their facial structure.
Signs Your Dog Is Expressing Emotion
Rather than crying tears of sadness, dogs express emotions through:
- Vocalizations such as whimpering, whining, or howling
- Body language including flattened ears, tucked tails, or avoiding eye contact
- Changes in activity like lethargy or hiding
These cues can indicate various emotions like stress, fear, excitement, or discomfort.
How to Tell if Watery Eyes Are a Problem
Look for signs that suggest a health issue rather than emotional crying:
- Persistent or excessive tearing
- Yellow, green, or bloody discharge
- Redness or swelling around the eyes
- Excessive blinking or pawing at eyes
- Behavioral changes indicating discomfort or pain
If any of these symptoms are present, consult a veterinarian for an appropriate diagnosis and treatment.
Caring for a Dog with Watery Eyes
To keep your dog's eyes healthy, you can:
- Gently clean the area around the eyes with warm water or a pet-safe wipe
- Prevent scratching by using socks on paws or an Elizabethan collar
- Trim hair from around the eyes to reduce irritation
- Control allergens in your home by cleaning and using air filters
Never apply human medications to your dog’s eyes without veterinary advice.
When to Seek Medical Attention
Consult a vet if your dog displays ongoing symptoms, as eye issues can quickly worsen and lead to complications, including vision loss. Some conditions require prescription treatment such as antibiotics, anti-inflammatory medications, or surgical intervention.
Understanding Canine Sadness
Dogs do experience emotions and can show signs of
sadness or depression, such as:
- Lack of energy or withdrawal
- Loss of appetite
- Reduced playfulness and enthusiasm
Providing support through routine, affection, and enrichment helps maintain a dog’s emotional well-being.
Emotional Crying: A Human Trait
Most scientists agree that
emotional crying with tears is unique to humans. While dogs are empathetic and sensitive to human emotions, their method of emotional expression is different. Further research may one day clarify whether dogs can produce true emotional tears, but for now, any tearing is generally considered a physical response.
Conclusion
Dogs may appear to “cry,” but it’s vital to understand that
dog tears are typically due to physiological reasons. Understanding your pet’s body language, vocal signals, and health symptoms is key to identifying emotional states and addressing any underlying issues. When in doubt, professional veterinary guidance ensures your dog receives proper care—both emotionally and physically.
