Do Dogs Cry - Dog Tears And What They Mean

In an updated for 2019 version of “Do Dogs Cry,” we investigate dog emotions and look at the way our Labs show us how they feel.

If you are a dog owner, then you surely understand that your canine has feelings. And research increasingly supports the view that dogs experience a range of emotions.

A study in 2016 showed that dogs are able to recognize emotions not only in other dogs but in humans too. In addition, many dog owners share stories about their dogs trying to comfort them when they are crying or upset.

Excitement, fear, love and anger are some emotions that your dog is likely to feel.

When trying to understand your canine’s emotional range and figuring out their overall health needs, you may wonder whether your dog feels sadness and cries like a human.

You also may be curious whether they cry due to pain or illness.

Keep reading and we’ll discover whether dogs feel sad and if they shed real tears.

Do Dogs Feel Sadness?

Unlike humans, dogs become emotionally mature early and have an emotional range equivalent to a two- to two-and-a-half-year-old child.

If you are familiar with toddlers, then you certainly know that they cry. Like a toddler, dogs feel emotions like fear, distress, anger, and suspicion.

Do Dogs Cry: Dog Tears And What They Mean
We know now that dogs experience a wider range of emotions than previously thought.

These emotions are related closely to sadness. However, more complex emotions like shame and guilt never develop in dogs. So, dogs do not feel sadness quite like humans do.

Despair, remorse, depression, dejection, and misery are a few words that you might use to describe your own sadness. But when it comes to your dog, stress, discontentment, and uneasiness are better descriptors.

Do Dogs Cry When Sad?

When a dog is sad, you may see telltale signs that it is upset.

According to the American Society for the Prevention of Cruelty to Animals (ASPCA), canines have specific types of body language that can tell you how they are feeling.

While body language may not directly indicate a specific emotion, it can tell you if your dog is content, scared, or feeling aggressive.

Relaxed features indicate contentment. When relaxed, your dog’s mouth will be slightly open with the tongue out, and it may be panting. Its eyes may almost seem to be squinting, and the ears and tail will be in neutral positions.

In the case of fear or stress, your dog may take a submissive posture. Eyes will be partially closed, the ears will be pinned back against the head, and the tail will be between the legs. You may also see the mouth closed and the snout angled toward the floor.

It may seem as though your dog is cowering in front of you.

When your dog is in distress, you may notice some vocalizations.

Stress vocalizations include high-pitched barks, whimpering, and yelps. Yelps, whines, and whimpers may also indicate that your dog is experiencing pain. A dog in pain is more likely to growl or bite, so use caution if you think your dog might be suffering.

In some cases, you may even notice your canine companion mimicking human words or sounds. This is a common tactic your dog may use to show affection if you have reinforced this behavior.

While all of these things may be noted, there is one thing you will not seeyour dog crying tears.

Can Dogs Cry Tears?

You may want to know, can dogs cry? Yes, dogs can shed tears.

However, they do not cry in the way we do in response to emotion. To understand tears and crying, it may help if we take a look at how a dog’s eyes are constructed.

Dogs have the same basic eye structure as other mammals. The cornea, lens, conjunctiva, and sclera make up the different tissues within the eyeball, just as they do in our eyes.

Do dogs have tear ducts? Yes they do, and dogs can make tears to wash out their eyes
Sore eyes can be very uncomfortable and a symptom that something is wrong.

The eye sits in the orbit—or eye socketand is protected by the upper and lower eyelids.

The tissues of the eye need to be kept moist. Moisture lubricates the tissues so the eyes can move smoothly in the socket and the eyelids can glide over the eyes.

We all know how uncomfortable dry eyes can be, and it’s the same for dogs.

Moisture also helps to wash away grit and debris that can scratch the sensitive surface of your dog’s eye.

Humans have a fairly simple lubrication system that involves the secretion of fluid from glands. They are called lacrimal glands, tear glands to you and me, and each eye has one.

These glands release fluid that is then forced over the surface of the eye with the help of your eyelids.

Do Dog Tears Differ from Human Tears?

Yes, our dog’s tears are different from ours.  Dogs have much more complicated lubrication and eye moisture systems.

First, canines have a third eyelid located in the inner portion of the lower eyelids. This third eyelid, or nictitating membrane, is a clear structure that moves over the eye to protect it. It also moistens the cornea while maintaining vision and produces lymph fluid that helps prevent infection

Why do dogs cry tears - well, dogs like this French Bulldog are prone to eye problems
Flat faced dogs like this French bulldog are vulnerable to eye problems that cause watering and tears.

Dogs also have three types of glands that provide moisture for the eyes. These glands work together to produce the moisture your dog needs to keep its eyes healthy and functioning properly.

They are the lacrimal glands, like humans have, the meibomian glands and mucus glands. The lacrimal glands create watery tears, the meibomian glands produce an oily tear while the mucus glands produce mucus.

When your dog blinks, these three are mixed together. This creates a thicker fluid that takes longer to evaporate and offers better protection to the eyes.

Is Your Dog Crying Tears?

No, your dog isn’t crying tears of sadness. Dogs do not cry when they are sad.

In fact, humans are the only beings that cry. According to Scientific American, humans even stand out against other primates as the only animals that cry emotional tears.

So, what is going on if you see dog tears? Well, it is likely an issue that requires the assistance of your veterinarian.

In medical terms, the excessive production of tears is called epiphora.

Epiphora is a medical condition that can be caused either by disease or a congenital disorder. In the case of a congenital disorder, your dog may be predisposed to watery eyes due to the shape of its face, particularly the eyes and nose. Excessive tears may cause red or brownish stains.

Congenital epiphora conditions are most commonly caused by the turning in of the eyelashes, the folding inward of the eyelids, or the bulging of the eyes themselves. 

Labrador Retrievers, Cocker Spaniels, Bulldogs, Pugs, and Mastiffs are just a few breeds that are prone to these sorts of issues. 

Other symptoms of epiphora include:

  • redness
  • crusting or discharge
  • eye sores or ulcers
  • odor
  • loose or inflamed skin around the eyelids
  • squinting.

If your dog is exhibiting these symptoms, speak with a veterinarian as soon as possible. Treatment should be provided right away so your dog feels as comfortable as possible.

Treatment may be as simple as applying a topical medication daily or as complicated as corrective surgery.

What Causes Tearing?

If not caused by a congenital issue, a medical issue may be causing the eyes to water excessively.

The following conditions may result in excessive tearing:

  • foreign matter or debris in the eye
  • conjunctiva infections
  • sinusitis or acute sinus infections
  • allergies
  • tear duct obstructions
  • immune-related illnesses.

In order to diagnose the cause of epiphora, your veterinarian may need to use imaging tests to find the problem.

  

Specifically, X-rays may be needed to find eye abnormalities. Imaging and visual examinations may be done with contrast dyes to help your veterinarian distinguish the structures of the eye.

In situations where simple tests cannot be used to locate the issue, the veterinarian may order blood tests, MRIs, or CT scans. In cases where a serious issue is suspected, but cannot be positively identified, surgical exploration may be required.

Do Dogs Cry – Summary

Dogs produce excessive tears from their eyes in response to injury or infection or due to inherited problems with their facial anatomy.

Dogs don’t cry tears in response to emotions, such as sadness or fear, or when they are in pain.

That doesn’t mean that dogs don’t feel emotions. On the contrary, recent research shows that dogs experience and understand a range of emotions. Learning how dogs display their emotions through body language can help us understand them.

If your dog’s eyes are producing excessive tears, they are likely to be sore and uncomfortable, so do get it checked out by a veterinarian as soon as possible.

  1. When 9/11/2001 happened and i sat watching the news for days and crying, my lab slept by my side in my arms for two nights. She never did that before that night or again after that. She knew I was in utter despair as was the rest of our country, and that I needed her.

  2. I groom and board dogs and all my dogs are rescue dogs, some from appalling backgrounds. Dogs do cry by howling – finishing the howl with a wow, wow, it is the most heart rendering sound to hear. Dogs also suffer from depression particularly if in an abusive situation over a period of time – in this case the dog ‘switches off’ and just goes through the motions of living – this is very similar to a human. This can also occur following major trauma. Some dogs recover from their abusive situations but this takes time, patience, however, if the abuse is so severe, the dog may never recover as the memory may be triggered by sight, sound or smell.

    If you read ‘Elephant Tramp’ by George Lewis – the story of a training routine for Sadie the elephant is told
    ‘Sadie just could not grasp what we were trying to show her. In frustration she attempted to run out of the ring. We brought her back and began to punish her for being so stupid. We stopped suddenly, and looked at each other, unable to speak. Sadie was crying like a human being. She lay there on her side, the tears streaming down her face and sobs racking her huge body.’ …. So yes, other animals do cry !!!
