Dogs sigh to express their emotion. Sometimes a dog will sigh if they are feeling content, while other times it could signal underlying anxiety. Your dog may also sigh more if they know it will get your attention.

When dogs sighs, they will take in a deep breath and exhale, usually quietly. Occasionally, you may hear a faint noice as the air travels through the vocal chords. It should sound like an extended breath with a small hint of emotion.

Why do dogs sigh?

Sighing in dogs can reflect several feelings, including boredom, contentment and disappointment.

"Dogs use their body language and behaviour to communicate and sighing is just another way that they show how they're feeling," PDSA Vet Nurse, Nina Downing, tells Country Living UK.

Do dogs sigh when they are annoyed?

"To work out what a sigh means, you need to look at the whole situation. If your dog is looking at you expectantly when they are due a walk and then you instead go and sit down with a cup of tea, your dog may walk off and lay down with a big sigh; this is their way of showing their disappointment."

If your dog is feeling content, you may notice they will appear relaxed with their eyes half closed, body loose. Nina adds: "A dog sitting upright, wagging their tail, staring at the treat tin may sigh a big, deep sigh, if you're not being quick enough in responding to their request! Dogs are communicating with us all of the time, we just need to read them to understand them."

If you are unsure about your dog's behaviour, always head to your local vet.
