Splooting is when a dog or cat lays on his belly with his hind legs stretched out behind him. There’s no known scientific reason why some animals like to sploot, but it’s most likely because stretching their back legs feels good.
They may also do it on a hot day to press their bellies closer to the cool pavement or shaded grass.
Not every dog that stretches this way is considered to be splooting. Sometimes, pets who stretch their legs do that because they’re in pain, which could be caused by arthritis or hip dysplasia, so make sure that you rule out any medical problems before you go aww!
