I hope you have already had a good "outcome" to this situation, considering when you asked it. Barring a size or amount your dog may have ingested that could potentially cause/or lead to a blockage internally. With that said generally speaking what goes in one way, will usually come out the other way. Should there be a blockage general what goes in, does not find its way out-this would be a good time to be on the way to your vet.
