The amount ingested calculates out to about 1600mg/kg. This is a potentially toxic dose. Ideally, Cooper should be examined by your veterinarian or at the nearest veterinary ER. Either can induce vomiting via injection since the ingestion occurred less than 2 hours ago. Activated charcoal may be given afterwards to further reduce absorption. Excess magnesium may cause gastrointestinal upset, depression or negative cardiac or nervous system effects. You can also contact the Pet Poison Helpline. There will be a fee for the call. They will work with you and your veterinarian to help Cooper through this episode. Their number is 855-764-7661.
