Hi there --
Welcome to Just Answer.
THe biggest single piece of information I am missing is how big your dog is ---
If he is bigger than 50 lbs -- this would likely pass --
I would give about a teaspoon to a tablespoon of olive or mineral oil to help lubricate the system -- too much will give diarrhea. This should pass in 3-5 days.
If your dog is less than 30 pounds -- this may not pass-- so you will need to watch for indication of any blockage (lack of stools, loss of appetite, tiredness, abdominal pain, and vomiting) . Any of these would indicate an ER visit
In between these -- it may or may not cause an issue --
Another couple of points ----
1) If Your dog just ate this in the pst 1-2 hours--- then inducing vomiting with hydrogen peroxide (1tsp per 5-10 pounds) with bread --- usually takes 20 minutes -- and can be repeated once. This is ok to do if your dog is in good health
2) The best approach would be to go to yrou vet and have an x ray done to see whether this has been eaten -- as it may not have. This will show where it is and how much problem it may pose.
3) There can be removal of the object surgically or by endoscope (if it is in the stomach)
before it could cause a problem.
If you have questions -- you can write me back --Shortly -- I will be away for an hour or so --
