Welcome to Justanswer! I am Dr. Altman and happy to assist you both today!
There is a good chance that if she is >50 pound this will pass but it is simply not worth the risk. If your dog ingested this within the last hour then you can induce vomiting with 3% hydrogen peroxide 1 tsp per ten pounds then walk around to mix it in the stomach and agitate the lining. If no vomiting within 10-15 minutes it can be repeated once only in hopes of inducing vomiting.
If there is no vomiting:
1.) Feed 3 pieces of bread
2.) Take a nice walk to help move the material through. Not running around but a leash walk which helps encourage emptying of the stomach and digestion
3.) In about 2 hours repeat the bread which is used to help bulk up the foreign body to hopefully push them through
4.) Monitor for signs of the material coming out the other end in the next 24-48 hours
5.) Again tomorrow a few nice long leash walks to help encourage gi motility and pushing the foreign material through the intestinal tract
This is the difficult part, the watching and waiting because all we can do is see if it passes on its own but if at any point there is vomiting (after tonight with the peroxide) then please consider a veterinary exam
Please let me know if I can be of any further assistance to you both
