My two dogs at chewing gum yesterday...?!?

I've had dogs chew already chewed gum (sc it up off the sidewalk, off dog show floors, etc.). They were Dalmatians and Dachshunds. Not had any problems. If they were poisoned it would have shown up by now. I wouldn't worry unless they begin vomitting. As long as they have bms today that are normal, there is no blockage, either. Just watch. After today I wouldn't worry at all.
