Dogs roll on their backs as a way to communicate submission or friendliness. It's an invitation to play or a sign of respect.
Rolling in something smelly helps dogs mask their scent. This behavior harks back to their wild ancestors who used it for hunting.
Dogs may roll on their backs to cool off on a hot day. Exposing their belly to the air helps regulate their body temperature.
Sometimes, it's all about an itch. Rolling allows dogs to scratch those hard-to-reach spots on their backs.
Rolling can be a way for dogs to claim their territory. They leave their scent on the ground and establish dominance.
In some cases, dogs roll on their backs simply because it feels good. It's their way of expressing happiness and contentment.
Every dog is unique, and the reasons for rolling on their backs can vary. Understanding your dog's specific signals is key.
