Thanks for the additional information Caryn....I really appreciate it.
The biggest concern I have with the cresent rolls is that the uncooked bread is going to rise in her stomach. This can cause a dog to have significant digestive problems including bloat.
The best thing to do is to get her to vomit up the rolls. The way to make that happen is pretty easy and instructions can be found here:
If you're unable to get her to vomit, I would recommend you have her seen by an emergency vet. The bread dough can be very be very toxic to dogs. The process of rising of the dough, the yeast produces ethanol. Dogs that eat raw bread dough may have a toxic reaction to the ethanol.
Signs that there could be a problem would be significan behavior changes, weakness, staggering, depression, and anorexia or lethargy. If this goes untreated, there can be respiratory problems, cardiac issues, and coma.
I hope this helps.
