What case is used for walking a dog? - in detail
In Russian, the case used for expressing the action of walking a dog is the instrumental case. When forming a sentence about this activity, the word "собака" (dog) would be declined in the instrumental case, which is typically marked with the preposition "с" (with). For example, the phrase "гулять с собакой" translates to "to walk with the dog." This usage is based on the principle that the instrumental case indicates the means or instrument through which an action is performed. In this context, the dog serves as the means by which the activity of walking is carried out, hence the use of the instrumental case.
