I probably wouldn’t worry about it too much. First just keep an eye on her and make sure she doesn’t start acting weird. Laying around more than normal, drinking more than normal, etc. If the puppy can get it down her throat 2 things will either happen. If the strong stomach acid won’t tear it down, which it typically will very quickly but if it doesn’t it will come back up and she’ll throw up. I honestly wouldn’t worry about, my puppy ate a dead bird last year and pooped the feathers out within a couple days. Puppies and dogs for that matter eat whatever, wherever they can and don’t typically have issues with it. If it was a piece of wood or something, it’s no problem.
