When a dog rolls over and reveals their belly to you, you can't help but feel special — and, of course, give them a good scratch. But why do dogs like belly rubs? And if your dog doesn't roll over for you, does that mean your pet doesn't like you? Let's take a look at the science behind a dog belly rub.

Why Do Dogs Like Belly Rubs?

It's important to first understand why dogs show us their bellies at all. When a dog lies on their back with their belly and neck exposed and tail tucked between their legs, they're communicating to show you they trust you. They're putting themselves in a vulnerable position, exposing very sensitive parts of themselves and trusting that you won't take advantage of that.

Many pet parents interpret their dog rolling onto their back as an invitation for a belly rub. And for some dogs, that's exactly what it means. After all, getting a rubdown feels good! When you pet your dog, they release endorphins, the feel-good hormone, and their levels of oxytocin, the bonding hormone, go up, says Wag!. And, similar to a scalp massage for you, petting your dog provides them with positive hair follicle stimulation, says ZME Science.
