As a caregiver, your four-legged friend’s behavior might sometimes leave you baffled. One such behavior that you might have noticed is your dog sleeping with its tongue out. This is a common phenomenon, but did you ever stop to wonder why they do it? Let’s explore the reasons behind this adorable yet intriguing behavior.
1. A Sign of Complete Relaxation
When your dog is in a deep sleep, they enter a stage called the REM (Rapid Eye Movement) cycle. During this phase, their body relaxes completely, which may cause their tongue to slip out a little. It’s the equivalent of us snoring when we’re in a deep sleep.
“Dogs are most vulnerable when they are asleep, so they only enter this total relaxation phase when they feel safe and comfortable,” says Dr. Jennifer Coates, a veterinary advisor.
2. They May Be Too Hot
Dogs don’t sweat like humans do, so they use panting as a method to cool down. If your dog is sleeping with their tongue out, it might be because they’re trying to cool down, especially during hot weather.
| Weather | Dog’s Reaction |
|---|---|
| Hot | Tongue Out |
| Cold | Tongue In |
3. It Could Indicate a Dental Problem
Sometimes, a dog sleeping with its tongue out could indicate a dental problem. This could be anything from loose teeth, gum disease, or even an overbite.
- Loose Teeth: If the teeth are loose, the tongue might slip out.
- Gum Disease: Inflamed gums can push the tongue out.
- Overbite: An overbite can make it difficult for your dog to keep its tongue in its mouth.
4. It’s a Breed Characteristic
Some breeds are more likely to sleep with their tongues out than others. Breeds with shorter snouts, like Shih Tzus and Pugs, often sleep with their tongues out due to their unique facial structure.
“Brachycephalic dogs have shorter skulls, which can sometimes lead to the tongue sticking out,” explains Dr. Coates.
5. It Could Be a Sign of an Underlying Health Issue
While rare, in some cases, a dog sleeping with its tongue out could be a sign of an underlying health issue, like neurological disorders or even a stroke. If you notice any other strange behaviors along with this, it’s best to consult with a vet.
