Have you ever wondered what makes your dog sigh? They might be subtly trying to communicate with you.
Have you ever been sitting on the sofa, or working away at your home office, when your dog lets out a huge sigh? Are you curious about what they might be trying to say, or if they are suffering from something in silence?
What Is A Sigh?
Before we go over the reasons why a dog might sigh, we should probably understand what a sigh is. You most likely already know what a sigh is. In fact, you’ve most likely sighed before.
A sigh is defined as a long and deep breath that also emits some form of emotion. A sigh is also twice the length or volume of a standard breath according to science.
But when it comes to understanding the cause of a sigh, regardless if it’s from a human or a dog, you need to know the context that led up to the sigh. If our furry friends emit some type of sigh, we need to understand the events that led them to sigh and try and piece the clues together!

There are a lot of different reasons why your dog might sigh.

Why Do Dogs Sigh?
When people sigh, it’s usually associated with feelings of relief, sadness, or exhaustion. But what if your dog sighs? Here are some reasons why your dog might sigh.
-
They are Happy and Comfortable
If your dog sighs during sweet, comforting, or relaxing moments, then their sigh might mean that they are happy. For example, if your dog sighs during any of the following activities:
- when you pet them;
- when they snuggle up next to you; or
- when you give them a big hug.
This could simply mean that they are happy. Humans tend to let out a sigh when they’re happy, and this is also true for our dogs.
-
They’re tired.
If your dog lets out a sigh at the end of the day, this could mean that they are tired and ready to hit the hay. We do this too when we’re tucked into the bed and ready to go to sleep. So the next time your dog lets out a deep sigh as the day comes to a close, just know they are cosy and entering relaxation mode.
-
Feeling Overwhelmed
If your dog appears to be stressed out when they let out a sigh, this could mean that they feel overwhelmed at their current situation. In this situation, your dog may exhibit other symptoms of being overwhelmed, such as growling, huffing, or trembling. If your dog is sighing as a sign of nervousness or struggling to cope with their current stress, it’s probably best to remove them from the situation.

Your dog might sigh because they’re happy, tired, or overwhelmed. You should look for clues in their environment to figure out which one they’re feeling!
