My mom bought fish for lunch, so I made some marinade for them, and pan-fried them. It only took a second for the back bone to fall to the ground, with all the little bones on it. My brother managed to catch one of our dogs, but the other ran forward and swallowed it. It only took a second. So I got so afraid, this could do serious damage to his internal organs, so my mom and I took him to the vet. The vet said there was nothing to do, and if we're lucky the thing will get out with food. I'm afraid, still afraid.
