I woould advise you to call the company on the back panel and ask concerning the ingredients. I can't find the ingredients online. Make sure the ingredients do not pose a health hazard. Dryer sheets usually pose a problem ONLY from the aspect of GI impaction. So depending on how many they ate and how big of a dog they are........
I think you have a couple options:
1. Take them to the vets office-obviously what we would recommend
2. Induce vomiting-feed a couple slices of bread to help surround it and then give 1tbsp of peroxide every 5 minutes until they vomit-obviously do this outside if you can.
3. If you can't make them vomit and the ingredients are nontoxic then feed a cushion diet of bread, mashed potatoes, rice with a little boiled chicken or beef-this type of diet is used to push things thru the system-feed it for 3-5 days and monitor the stools.

In any case you need to watch for evidence of obstruction......vomiting, not eating, lack of stool production, belly pain.
Good luck and let me know how it turns out!!
