Hi, my lab and whippet mix ate some field corn that I put out for deer and now she keeps throwing up everything. Should I take her to the vet?

If she ingested a cob, she should be seen by your vet as the cob may cause a GI obstruction. Moldy corn poses risk of aflatoxin toxicity and requires veterinary attention. If was regular, fresh corn off the cob then large quantities can cause GI upset such as vomiting and diarrhea. Withhold food for 12-24 hours. Allow small amounts of water or unflavored PediaLyte. Resume feeding a bland diet (1:1 ratio of plain boiled boneless chicken and plain white rice). Feed in small, frequent amounts waiting at least one hour between feedings. If the vomiting stops, transition slowly to the regular diet. If not, see your veterinarian.

    I'd schedule a visit with your vet ASAP if Maggie is unable to keep anything down at all and is acting very ill. In the meantime, keeping her comfortable, providing water at all times, and not giving any food, people snacks, or treats for several hours to help keep her stomach from getting more irritated. If she worsens, is in distress, or is vomiting without stopping, looking for an emergency vet near you is best.
