Dream of eyes, hands, puppies

I dreamed I had 2 sweet Rottweiler puppies and I took them outside to use the bathroom. I was also feeding my cats and the puppies got along great with them...even sharing the cat food with them. I remember thinking that when they grow up the would really be able to protect me. Then all of a sudden a lanky, long haired evil gray dog with yellow eyes jumped up on the rail of my deck and he was in a crouched position. He looked me straight in the eyes and I somehow knew him and knew he was evil. I felt like I had dealt with him before. He bared his teeth and I was scared but I shooed him away by stomping my foot and using my hands. It worked and he ran off. I just can't shake the feeling I got when he looked me straight in my eyes.
