I just went outside and fed the dogs, and I was going to give them a hot dog that was leftover... so I opened the pen, and my un-obedient or my Dad's "huntin' dog" jumped up, grabbed the sack, and ran away from the other dogs. Then the other dogs chased after her, and she swallowed the hot dog and the sack... in one bite. The sack is one of those little sandwich bags... really thin, and doesn't have any "zip lock" stuff on it. This dog has eaten an ENTIRE QUAIL several times... and she's been okay. I'm kinda worried about her. She continued to run around and jump and play after she ate it. How long should I keep a good eye on her??? About how long does it take for something to "pass" in a dog??? Oh, she's a Llewellin Setter by the way... if size matters. She's the black and white one in the signature pic. Thanks in advance.
