Our black lab did this once...she slunk in the room with what looked like a cone around her neck, but turned out to be the bathroom trash lid. Her look said, "Um, I...uh, please don't be mad, but I...uh, need a little help...." Laughed until we cried.
This is Freyja. She is beautiful! We also adopted a stray Husky/Golden mix with heartworm. Best dog we've ever had. We went through BIG DOG RESCUE PROJECT NW. They were awesome! they are paying for his meds, too!
