Why do dogs do this??

My Maggie does that all the time. She can fling a divit of grass
halfway across the yard. Smokey does not do this at all,never has.

I think the reason is they are marking scent, or covering scent like
their ancestors wolfs.

Yes, it's a "distribute my "mark" so I look like a BIG dog tactic left over from the wolf! I recently dog sat for a friend's two dogs, and one of them did that consistently, even in his own, fenced in yard!

My chihuahua does this. She also wants to pee right where one of the other girls just went. It's like she wants to cover their scent. You learn something new every day with these pups
