How do your emotions affect your dog?

You may have heard that dogs “lip lick” or “tongue flick” when they are stressed.  A recent study by Albuquerque et al. (2018) used lip licking in dogs to assess their ability to respond to emotional cues in humans and dogs.  Previous research suggests that dogs can differentiate between happy and angry facial expressions in both humans and dogs.  This paper took that concept a step further and asked if dogs are able to respond appropriately to those emotions.

Why is this important?  How dogs respond to our body language and emotional state influences our relationship with them.  It’s possible that dog who struggle to recognize and correctly interpret our emotional state also struggle to adapt well to family life.  Imagine that Fluffy steals a favorite shoe.  Her owner is furious, but Fluffy does not recognize this – or maybe doesn’t care.  As a result, Fluffy may be more likely to repeat the same behavior in the future, leading to more tension between her and her owner. On the other hand, dogs that are overly sensitive and responsive to an owner’s emotional state may struggle as well.  For example, Lassie may have a difficult time regulating her own emotions when family members get emotional, increasing the likelihood of mouthing or even aggression in times of emotional intensity.

This also has implications for dog-dog interactions.  It’s easy to see how dogs that are insensitive – or hypersensitive – to other dogs’ social cues might have a difficult time interact appropriately with other dogs.

Methods

Seventeen dogs of various breeds and ages participated in the study.  About half were male, half female.  This is a small sample size, yes, but this is typical in cognition studies on dogs because it is often difficult to recruit dogs.  The dogs were simultaneously presented with pictures of humans or dogs – happy/playful or angry/aggressive – and sounds (positive, negative, neutral).  During the presentation, the dogs’ body language was observed and recorded.

Results

Dogs mouth licked significantly more often when they were looking at negative (angry or aggressive) faces than positive (happy or playful) faces.  They also licked more often in response to human faces, compared to dog faces.  Interestingly, the sounds had no effect on their behavior.

Conclusions

(A note about language:  You may notice in the paragraphs below that I use a lot of words like “suggest”, “could” and “may”.  This is intentional.  This is a single study and as a result, we need to be careful about reaching strong conclusions.  The results are interesting and I think it is worthwhile to keep them in mind when working with dogs, but until we see the same kind of results replicated many times, we don’t want to make definitive conclusions.  For that reason, I avoid words like “definitely”, “clearly” and “do”.)

The results suggest that dogs may react appropriately to negative emotions.  That is, dogs seem to be able to interpret these negative facial expressions as what they are – an indication of a negative emotion.  Further, their interpretation triggers a corresponding emotional response in the dog, indicated by mouth licking.  If the mouth licking was a more general response to stress, you would expect to see it consistently across ALL conditions.  Instead, they only showed increased mouth licking when presented with images of negative emotions.

This may seem self-evident to many of us – yes, dogs know when you are upset and it impacts their behavior.  However, having observations tested by research is always a good idea.  Remember how much trouble we got into by making assumptions about dominance in dogs without good research?  It can lead to all kinds of misconceptions, which can have serious implications for animal and human welfare.  In addition, basic research like this allows us to lay the groundwork for exploring deeper, more interesting questions.

For example, the researchers speculate that social cognition – including the ability to read, interpret and respond appropriately to emotional cues in group members – plays an important role in social cohesion.  That is, dogs that struggle with this task may not cope well in group situations.  This could lead them to struggle in a family environment.  Now that we have some evidence that dogs can respond and react to these cues, we can start to ask other questions like:

  • Are dogs that are less sensitive (or hyper sensitive) to social cues more likely to have behavior problems?
  • Are they more likely to be rehomed?
  • Why did they respond more to the faces of people than dogs? Does this have implications for dog-dog relationships and dog-dog aggression?  Is this related to selective breeding – are we inadvertently focusing more on dogs’ behavior toward people than other dogs?  If so, is this leading to increasing levels of dog-dog aggression?

Applications

How can you use this information to apply to your life with dogs?  Try to be aware of how your mood is affecting your dog.  Is you are stressed or angry, that may not be the best time to train your dog.  Or, maybe that’s a good time to give them something else to do – like chew on a Kong or play outside for a while – so that you don’t get overly frustrated with them.  If you work with clients, make sure your clients understand that dogs are impacted by their negative moods and facial expressions.

I also think there is value in filing this information away.  Think about it when you are interacting with and observing dogs.  Stay up-to-date on future research on social cognition in dogs and gradually build up a strong picture about what we think is going on inside their heads.  This will inevitably make you a better at training, living with and working with dogs.

Are there other questions that came to mind when you read the results of this study or other ways you can think of to apply this information to working and living with dogs?  Please share your thoughts in the comments section below!

  1. I read your article about how our emotions affect our dogs.
    I have been always an emotional person, I’ve had losses and struggle with love life issues. We got our Dog about 9 years ago, She is a Border Collie mix Austerian Shepherd, her name is Sparkles. She has been a great companion and loves going on walks, Although I have noticed that she , I believe loves my husband more. She rarely licks my face, and runs away when I’m crying. Which makes me cry more, because I love her, feed her, walk her everyday, we spend time in the yard. I’m with her 19 hours a day, But She does not comfort me if I am hurting, and I am still grieving the loss of my Parents for 7 years now. And I have no children, my husband works long hours, So I guess , I’m lonely alot. But she is company and wants walks, but why does she not comfort me when I cry, I’ve been so hurt by this for years.
    We had 2 dogs before and the beagle which was my baby Bingo always came to lick my face and sat beside me, I miss him, He was my world. He lived 13 years and died in 2010 . The other dog died 3 months later, but Bingo was the dog who understood my pain.
    So After Bingo died we got Sparkles, I didn’t notice anything different at first but when my Parents died, I was devistated, and Sparkles just never filled that void for comfort, Basically she will sit next to me but her affection goes to my husband. He is stable and firm, non emotional type man, But I need support, Am I expecting to much from my dog, I hear stories of closeness and love of animals comforting the hurting, I got that from my beagle, but not Sparkles. If I am happy she seems happy, but If I’m Sad or crying she runs and hides. Is it something with her do I make her run away with emotions? Any advice is appreciated.

    1. Great question. I think how a dog reacts to someone when they are feeling upset varies a lot from dog to dog. Some dogs are very sensitive to our emotions and will solicit attention when we cry. Other dogs seem to be completely oblivious or unmotivated to interact when we’re emotional. Other dogs seem to be scared of crying. I don’t think it has anything to do with you and would hesitate to say it means she’s less attached to you than to your husband or than your other dog was. They just have different personalities! Maybe you could try to find a fun way to interact together, like doing some trick training or going on walks to a favorite nature area.

    1. Yes! If we train our dogs using intimidation and pain, they can experience fear and anxiety. On the other hand, training using positive reinforcement can generate positive emotions in our dogs because they associate training with good things. Having clear expectations for our dogs is also very important. If they don’t know what is expected of them and/or feel they have control over their environment, that is another source of stress that can create negative emotions as well.
