Wow. It sure is scarey when something like that happens to one of our animal family members, isn't it? Glad your dog is okay.
It is amazing the items that dogs will swallow that eventually come out the opposite end, often with a little pulling and tugging!
I was at a dog show in May and my dog's breeder had a dog swallow a leash. It also came out fully intact. I don't recall if there was assistance needed - but probably.
That kitchen knife incident that Gollick shared is one of the worst ones I have heard about.
When glass accidently falls and breaks in my kitchen, I immmediately order my 4 munchkins "Outside! Outside!" and they run out the doggie door. They aren't allowed back in until I have made sure I have gotten all the pieces up -and that sometimes mean I end up with a sliver in MY foot (Of course I am always barefoot in the house - but never pregnant).
Be eccentric now. Don't wait for old age to wear purple.
