My 10lb Havanese ate a prenatal vitamin with iron. Will he be okay?
Oh no, that's not good that Atticus at one of your prenatal vitamins!. A toxic dose of iron is considered to be greater than 20mg/kg. He weighs 4.55kg, so he would need to ingest 91mg of iron to have a toxic reaction. Given that he has eaten only one pill and therefore ingested 27mg. this is not enough to cause toxic symptoms. That being said, it can cause GI upset, and it can take a couple of days for these signs to appear. You may see vomiting, diarrhea, lethargy, and/or anorexia. If you see any of those signs, withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. If the vomiting continues in the absence of food, he vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away. Hopefully, however, Atticus will be ok. Good luck, I hope this helps!
