Coco may be stressed from the visit or having a mild reaction to the vaccinations. You can try to offer her a small meal of boiled chicken and sweet potato or rice to see if this settles her stomach. However, if her vomiting persists or if any other signs of illness develop (like diarrhea, inappetance, or lethargy) I recommend having her examined by a veterinarian right away. Usually reactions to vaccines are mild, but in some cases they require medical treatment. Thanks for using Petco Pet Education Center, formerly Petcoach and I hope Coco is feeling better soon!

    I would recommend taking bully back to the vet. If he was vaccinated yesterday he could be having a vaccine reaction. However if he was sick previous to vet visit he will need more aggressive care. A wide range of things can cause vomiting I would need more information to help. You can try a bland diet of boiled chicken and white rice.
