If there was any zinc in the ingredients then that would be you toxic to the dog. From what I am reading, if I have the same brand you have , then making the dog vomit would be all that is needed. I do not see anything in here that would be toxic. Since you have made the dog vomit you may also want to give some very burnt toast to the dog to absorb anything left in the stomach. You may see vomiting, or diarrhea. Keep the dog well hydrated with 1/2 water and 1/2 children's pedialyte.
If there is suddenly a lack of appetite, stumbling or staggering, breathing difficulty or lethargy then you should have the dog seen.
