Raising legs to urinate is the behavior of adult male dogs. Female dogs, whether they are adults or minors, squat down slightly on both hind legs to urinate. The little male dog also squatted to urinate at the beginning. When he was seven or eight months old, he would not lift his legs to urinate. When he was old, he would not lift his legs to urinate. However, some stubborn bitches also raise their legs to urinate, but only slightly.
So, why does a male dog lift a leg to urinate?
It turns out that there is a smell called pheromone in dog's urine. Its concentration is only one in a few million, which can only be smelled out by the same species. When other dogs smell it, they know the size, sex, age and temperament of the urinating dog. In order to occupy the territory, the male dogs raise one leg and try to make their urine sprinkle higher, so that the smell is not easily covered by the urine of other male dogs. In addition, a higher pee indicates that the male is stronger and more attractive to the females.
