According to the ASPCA, the sweetener xylitol which is found in many sugar-free gums and candies can be harmful to your best friends. I wonder what it's doing to your kids.

Dogs ingesting significant amounts of items sweetened with xylitol could develop a fairly sudden drop in blood sugar, resulting in depression, loss of coordination and seizures. Signs can develop quite rapidly, sometimes less than half an hour after ingestion.
