Once we thought we had the whole "look before you move" down pact, this crazy cute mutt jumped out of her carrier. She slipped right through the hole for her head, right onto the cement. I screamed, she screamed, her back leg was tucked. She limped around...I gave her half an hour, or I would find an ER. She was running within the hour...but dont risk it, listen to your gut...if you want to take her in, do it for peace of mind...
