Why do dogs like to roll in the mud to play the dog is stupid?

Dogs rolling on the ground is an inherited behavior. First of all, it is important to understand that often the smell of feces, carrion and garbage is not at all smelly in their world, and these smells are even considered to be a sign of food. There is a theory that dogs like to roll around in places that are unacceptable to us, a behavior inherited from their ancestors, the wolves, and a way for them to bring advice back to the pack. Goodman, curator of the Indiana Wolf Museum, and assistants have extensively studied the behavior of wolves rolling in specific environments and smells. The study found: “When a wolf encounters a strong odor, it first smells and then rolls on it, getting the odor on its body, especially on its face and neck. Once it returns to the pack, its kind will come to greet it and probe in passing while greeting, probing the scent thoroughly. Then one or more of the wolf companions will track this brought back scent and find the source of this scent directly.” Dogs rolling around on the floor is deodorizing an odor we don’t like doesn’t necessarily mean they’ll hate it, and by the same token, an odor we like (perfume, body wash, etc.) doesn’t necessarily mean they’ll like it. Sometimes, after we help the dog after bathing or spraying, they are eager to rush out and find a place to rub and roll. No need to wonder, there is only one thing on its mind at the moment, how to get rid of this unacceptable smell you left on it! Some of the scents that humans enjoy, but in their smell is pungent and annoying to dogs, so they will choose to rub and roll to get rid of this dislike of the smell. Dogs rolling on the ground is rubbing itch or pain response when a part of the dog’s body feels itchy and can not scratch themselves, will choose to rub itchy by rolling; but sometimes the pain caused by internal organs, will also lead to their rolling behavior. But these two causes of rolling, but also better through their additional actions and expressions to complement the judgment. When dogs suddenly and frequently appear this situation caused by rolling behavior, it is likely that they have health problems, please owners should pay attention to and promptly take it to the hospital for examination.
