What Does It Mean When a Dog Cries Tears? Unveiling Canine Tear Production
What does it mean when a dog cries tears? While dogs experience emotional responses, visible tears in dogs, especially excessive tearing, are usually indicative of a physical issue irritating the eye, rather than an emotional expression like sadness.
Introduction: The Mystery of Dog Tears
The sight of a dog with watery eyes often evokes a sense of empathy. We naturally project our human experiences onto our beloved companions, assuming that visible tears signify sadness or distress, much like when we humans cry. However, canine tear production is more complex than simply expressing emotional pain. While dogs undoubtedly experience a wide range of emotions, understanding the true meaning of tearful eyes in dogs requires a deeper dive into canine physiology and potential underlying health conditions. This article, guided by veterinary expertise, clarifies what does it mean when a dog cries tears?, separating fact from fiction and providing practical guidance for pet owners.
Understanding Canine Tear Physiology
To understand why dogs “cry,” we must first understand how their tear ducts function. Like humans, dogs have tear ducts that produce tears to lubricate the eyes, remove debris, and fight infection. These tears drain through small openings in the inner corners of the eyes into the nasolacrimal duct, which connects to the nasal cavity. When tear production is normal and drainage is efficient, tears are rarely noticeable. However, several factors can disrupt this delicate balance.
Common Causes of Excessive Tearing in Dogs
Excessive tearing, or epiphora, is a common symptom that can be attributed to various causes.
- Allergies: Just like humans, dogs can be allergic to pollen, dust mites, mold, and certain foods. Allergic reactions can cause inflammation and increased tear production.
- Irritants: Exposure to smoke, dust, or other airborne irritants can trigger the tear ducts to produce more tears to flush out the foreign substance.
- Anatomical Issues: Certain breeds, particularly brachycephalic (short-nosed) breeds like Bulldogs, Pugs, and Shih Tzus, are predisposed to tear duct abnormalities or shallow eye sockets, which can hinder proper tear drainage.
- Infections: Bacterial or viral infections of the eye can cause inflammation and increased tear production.
- Blocked Tear Ducts: Obstructions in the nasolacrimal duct can prevent tears from draining properly, leading to overflow.
- Corneal Ulcers: Injuries to the cornea, the clear front surface of the eye, can cause pain and excessive tearing.
- Glaucoma: This condition, characterized by increased pressure inside the eye, can also lead to increased tear production.
- Eyelid Abnormalities: Conditions like entropion (inward rolling of the eyelid) or ectropion (outward rolling of the eyelid) can irritate the eye and cause tearing.
The Role of Breed Predisposition
Certain breeds are more prone to tear staining and related issues. Brachycephalic breeds, with their flattened faces, often experience poor tear drainage. Small breeds are also more likely to develop blocked tear ducts.
Diagnosing the Cause of Excessive Tearing
Determining the underlying cause of excessive tearing is crucial for effective treatment. A veterinarian will typically perform a comprehensive eye examination, which may include:
- Schirmer Tear Test: Measures tear production.
- Fluorescein Stain Test: Detects corneal ulcers or abrasions.
- Tonometry: Measures the pressure inside the eye to rule out glaucoma.
- Examination of the Tear Ducts: To check for blockages.
Treatment Options for Epiphora
Treatment for excessive tearing depends on the underlying cause.
- Allergies: Antihistamines or hypoallergenic diets.
- Irritants: Flushing the eyes with saline solution.
- Infections: Antibiotic or antiviral eye drops.
- Blocked Tear Ducts: Flushing the tear ducts under anesthesia or surgical correction.
- Corneal Ulcers: Antibiotic eye drops and pain medication.
- Glaucoma: Medication to lower eye pressure or surgery.
- Eyelid Abnormalities: Surgical correction.
| Treatment | Condition Addressed |

| Antihistamines | Allergies |
| Saline Solution | Irritants |
| Antibiotics | Infections, Corneal Ulcers |
| Surgery | Blocked Ducts, Eyelid Abnormalities |
Understanding Dog Emotions
While dogs don’t cry tears due to sadness in the same way humans do, they certainly experience a wide range of emotions. They express these emotions through body language, vocalizations, and behaviors. Understanding these cues is crucial for building a strong bond with your dog and recognizing when they are feeling happy, anxious, or distressed.
FAQ: What Does It Mean When a Dog Cries Tears?
Why are my dog’s eyes always watery?
Excessive tearing, or epiphora, can have many causes. It is most often caused by a physical issue like allergies or a blocked tear duct rather than sadness. Consult with your veterinarian for proper diagnosis.
Can dogs cry tears from sadness?
While dogs experience a wide range of emotions, including sadness, they don’t typically express it by crying tears in the human sense. When they do cry, it is most likely related to physical discomfort or irritation.
What is tear staining, and why does it happen?
Tear staining is the reddish-brown discoloration of fur around the eyes, common in breeds with light-colored fur. It’s caused by porphyrins, iron-containing molecules in tears. When tears don’t drain properly, these porphyrins stain the fur.
Are tear stains harmful to my dog?
Tear stains themselves are usually not harmful. However, the underlying cause of excessive tearing could be, therefore it’s important to consult your vet.
How can I get rid of tear stains on my dog?
There are many over-the-counter tear stain removers. Keep the area around your dog’s eyes clean and dry, and address the underlying cause of excessive tearing.
What breeds are prone to tear stains?
Light colored breeds such as Maltese, Bichons, Poodles, and Shih Tzus are known for tear staining. Breeds with shortened noses such as Pugs and Bulldogs are also prone to tearing.
What are the signs of a blocked tear duct in a dog?
Common signs include excessive tearing, wet fur around the eyes, and potentially a nasal discharge. Your vet can determine if there is an underlying obstruction and flush it.
Can allergies cause a dog to have watery eyes?
Yes, allergies are a common cause of watery eyes in dogs. Allergic reactions can cause inflammation and increased tear production, resulting in epiphora.
What should I do if I notice my dog’s eyes are constantly watering?
Consult a veterinarian for a comprehensive eye examination to determine the underlying cause of the excessive tearing and receive appropriate treatment.
Are there home remedies for excessive tearing in dogs?
While some home remedies, like gentle cleaning with a warm, damp cloth, can help keep the area around your dog’s eyes clean, it’s essential to seek professional veterinary advice to diagnose and address the root cause of the problem.
Is it possible for a dog’s tear ducts to be surgically corrected?
Yes, surgical correction is sometimes necessary for conditions like blocked tear ducts or eyelid abnormalities that contribute to excessive tearing.
Besides crying, what other signs indicate that my dog is feeling unwell?
Other signs of illness in dogs include changes in appetite, lethargy, vomiting, diarrhea, coughing, sneezing, and changes in urination or defecation. If you notice any of these signs, consult your veterinarian.
