Very good advice, but give in small doses. If your dog eats anything that may be harmful the peroxide trick should work but it has to be done very shortly afterwards. Only feed 1 tablespoon at a time until the dog vomits. If the dog is small to medium size & does not vomit after 4-6 tablespoons stop & notify the vet, if it is a large dog you may give 6-9 tablespoons. The dog will ussually vomit after 2-4. And administer it 1-2 minutes apart.
