How us humans sleep can say a lot about our personalities, our health issues, and even our relationships with others. But it’s not just OUR bedtime positions that can be revealing — how our four-legged friends’ sleep can tell us plenty, too.

You might notice that your furry pal sleeps in a very specific way and it might not be a happy accident. How your pet nods off can be very insightful into how they’re feeling mentally and physically.

Here are the seven most common pet sleep positions you’ll find your dog in and what they mean.

1. Crazy Legs

You might not have heard of the “crazy legs” sleep position — but you’ll know it when you see it! This position has your pup on their back with all four legs splayed up in the air.

Dogs that sleep like this are showing a combination of submission and vulnerability. With all four legs in the air, a dog’s stomach and organs are completely exposed, which means they are probably independent, laidback, and feeling very comfortable in their space.

2. Side Sleeper

If your doggie is passed out on his or her side, they’re in a common sleep position that is typically reserved for naps. However, it is possible for some dogs to sleep like this for longer periods of time.

The side sleeping position is a relaxed one and again demonstrates complete trust since the pup’s tummy is exposed. Side sleepers are usually very calm, care-free, usually have a strong bond with their families.

3. The Superman

Or, more appropriately, the Super-Pup! Any pet that falls asleep stomach down with their legs stretched outward is drawn to the “Superman” position.

This position is popular in puppies, mostly because it’s an easy position for a dog to wake up and jump right back into playing. As a result, the Superman position is definitely an indicator of a fun, energetic canine!

4. Legs Up, Back Down

Similar to the “Crazy Legs” position, this option sees a dog’s front paws laying over their chest while their back legs are extended completely in the air. In this position, a dog can be lying on either their back or their side.

This position may be a sign that your dog is warm and trying to cool down; since a dog’s paws contain sweat glands, and their belly has the least amount of fur on their body, this is the ideal position for bringing down body temperature. 

Be aware careful, though — if your dog has their paws curled over their chest while in this position, they are telling you they don’t want to be bothered. They could be on-guard if you try waking them up.

5. Belly Curl

Yes, dogs can be tummy sleepers, too! In the “Belly Curl,” your dog will be sleeping on their tummy, often with their front paws tucked backward.

This tightly-wound position may indicate your pup is not getting the best quality of sleep. According to Dog’s Best Life, this is because the position does not allow for a dog’s muscles to relax enough to enter the deep, REM stage of sleep.

Many dogs who tend to curl are gentle and shy, but they can often be adventurous and sweet animals.

6. Curled Up

Similarly to the “Belly Curl,” dogs in the “Curled Up” position are sleeping in a tight, unforgiving position.

Because this position allows a dog to protect their belly and share heat in a pack, it is the most common position amongst wolves and wild dogs. If you catch your pup sleeping like this, it likely means they are either a bit cold or apprehensive about something, like a new environment or people.

But don’t worry, plenty of happy pups sleep this way! It’s just an incredibly warm, comfortable way for them to nod off.

7. Back-to-Back

If you have more than one dog in your home, you might notice that they sleep back-to-back. Wild dogs tend to huddle to together for protection and warmth in the wilderness, so back-to-back sleeping is an instinctual way for a dog to show you are one of the pack.

Pups can also do this with their human pack, too! According to Dog Time, back-to-back sleeping is a way for your pup to bond with you, showing you that they can trust you 100%. So, if your pup crawls into bed with you and presses their back against yours, they’re just showing you some extra love!
