My 8 lab puppies have opened their eyes! Scary episode today when one of them got his head stuck in the chain link fence on one side of their pen. Momma was freaking out attacking her pack mates who wondered what was with the screaming pup. I had to push his head back through the chain link, then spent 15 minutes getting momma to calm down. All fixed now so no more exposed chain link in the pen. Puppy is fine: I can't even tell which one it was.
