My Peaceful Terros

I have two beautiful dogs. Two Italian Greyhounds. Lucca, who is the older, more wiser chocolate brown and white (he looks black), and Leche who is the young baby still very active, fawn and white one. They are two real little gorgeous things, and for the most part, very sweet and cute and cuddly. However, they have their times where they are so uncontrollable that I want to give them away to the first bergie who knocks on my door. Like when I leave them at home and come back to find my carpet riped up, and chewed along with my couch and a few socks. Then I try to discipline them, but they have no idea why I am screaming at them and they look at me with that "run away, he has gone mad" look. I think they are at their best when they are sleeping. They are so peaceful and sweet then.....actually, it takes them a hour to get to sleep, they never lie still and they take over the bed. They are little terrors, but I love them soooo much. I just need to discipline them better. But how do you discipline someone that looks at you with those whites in the eyes, and the head hanging low and the tail between the legs. Its so tough!!!
