This is what a german shepherd had to endure for over 24 hours after she went chasing after a bunny.
Her head was stuck in an old stove pipe. After figuring out how to get her out, and what tools to use, it took over 30 minutes to cut her out.
The other German Shepherd in the picture (Tommy, her mate) is the one who actually found her and alerted the owner after he searched for over 24 hours. It took Tommy a couple of minutes before Tommy located her.
She seems to be fine, except for an abrasion to one of her ears and a superficial cut to her chest.
