What It Really Means When a Dog Shows You Their Belly

You’re arriving at your friend’s home, and their dog is greeting you at the door. They’re happy you’re here! Their tail is wagging, their tongue is out, and they flop onto the floor, showing their tummy. 

Are they simply begging for belly rubs, or should you have caution before going for it? 

Typically, dogs flipping onto their backs to show their stomachs means they’re begging for belly rubs, but the true reason why they’re showing their belly is a mystery. “We’d really have to talk to dogs directly, but I’m sure there are some dogs that get some pressure off their back by laying on it” or are scratching their backs, says Brian Lee, a Los Angeles-based dog behaviorist and owner at Way of the Dog.

If they’re truly scared, dogs won’t show their bellies. They need some confidence to be expose themselves in that way, Lee says. “That’s why you see your dog laying on his back while sleeping. Obviously, if it didn’t feel it was a safe environment, it wouldn’t sleep that way.” 

Similarly to when a person can’t be vulnerable or intimate due to trauma, their guard is up. When dog is in fight or flight, they won’t roll on their back. “That’s why a dog rolling on its back; in general, 90 percent of the time it’s a good sign,” Lee says. 

But what about when it’s not a good sign? 

Why would a dog show their belly if they’re scared?

Dogs aren’t always showing their bellies in a grab for attention or affection. A common reason is submissive behavior, also called a submissive rollover, says Sara Scott, a certified professional dog trainer who owns a training business the Bay Area.

“It’s sort of like the dog is saying, ‘I mean no harm to you, don’t hurt me’ as they roll over, which is the opposite of the dog saying, ‘please touch my body and pet me,’” Scott says. 

She adds that submissive rollover is something that animals do in the wild. In groups like wolf packs, exposing the belly is a way to appease and avoid conflict with more dominant pack members, showing that they aren’t a threat. “That said, our domesticated pet dogs are certainly not wolves,” Scott says. 

How can you tell belly exposure is being done out of fear?

“Body language doesn’t lie,” Lee says, adding that their body movements are all that animals can really use to communicate. Half the body can’t be comfortable enough to be excited for belly rubs while the other half is tense. “All the cues add up,” and it depends on the context, he says. 

If they’re doing a submissive or fearful rollover, the dog will be tense, with a stiff body and will either avoid eye contact or be showing “whale eye.” This is when their head is slightly turned, and their eyes are wide with the whites showing. 

Here are signs that rolling over isn’t for belly rubs, and people should take caution: 

• Closed mouth

• Yawning

• Licking their lips

• Tail is tucked

• Crouching lower

• Trembling

• Freezing in place

• Head turned away, with only the whites of eyes showing

• Moving away when someone reaches out

If a pup exposes their belly, that doesn’t automatically mean they want belly rubs. If a dog is showing any combination of the above body signals, they are “not feeling secure, and you should give them space,” Scott says.

What if they really do want belly rubs?

If a dog really is wanting belly rubs, their body language is going to be much different. “A dog that’s truly soliciting belly rubs will have a relaxed, wiggly body, tail wagging, open mouth (maybe with their tongue out), and will be making eye contact with you. They might even paw at you or nudge you, and they’ll approach you and then flop over,” Scott says. This is the go-ahead that rubbing the dog’s belly is safe, because they clearly feel comfortable and unthreatened. 

Some dogs learn to ask for belly rubs — and they will do it repeatedly. “In other words, they rolled over and a human touched their belly enough times that they started realizing that rolling over would produce the consequence of a belly rub,” Scott says. When they enjoy the belly rubs, they will roll over more and more frequently.

Lee has also worked with pet parents whose dogs roll over to beg for belly rubs constantly. “Owners can’t help themselves but bend over and pet the dog,” Lee says, adding that doing this repeatedly is “total manipulation.” If a dog is requesting belly rubs too frequently, Lee recommends to his clients that they only pet the dog when they are laying on their stomach to eventually train them out of the behavior. 

“Dogs are very good at working their owners,” Lee says. But just like they can show us they don’t actually want to be touched, we can also tell them “that’s enough” — well, if we can resist them.
