There is a theory that dogs like to roll around in places that are unacceptable to us. It is a behavior inherited from their ancestors "wolves", and it is also a way for them to bring advice back to the group.
Goodman, director of the Indiana Wolf Museum, and his assistant have extensively studied the behavior of wolves rolling in special environments and scents. The study found: "When a wolf encounters a strong odor, it will first smell it, then roll around on it, and get the smell on its body, especially its face and neck. Once it returns to the pack, its peers They will come to say hello, and while saying hello, they will explore and explore the smell thoroughly. Then one or more of the wolf companions will track the smell brought back and directly find the source of the smell."

Some fragrances that humans enjoy very much, but they smell pungent and annoying to dogs, so they will choose to get rid of this unpleasant smell by rubbing and rolling around.
