I have chips in mine, too. Katie was my escape artist but now at 16 she doesn't do it as often..still, she loves to find a neighbor out having coffee on their deck. Last time she did it the neighbor said, "This puppy was starving and she is shaking like a leaf! I fed her and wrapped her in a blanket." She had her breakfast about 30 minutes before she took off and she shakes a lot. She is a Silky terrier and weighs about 8 pounds...she is really an actress. You have to love them. Glad your boy made it home.
