Brown and white dog running through fall leaves on the ground.
Two dogs jump into leave piles
It is not clear if the first sentence is talking about one brown and white dog or one brown and one white dog. The two dog(s) were not jumping in the leaves, they were running through them. Also, the leaves were on the ground, not necessarily in piles.
