Pet's info: Dog | Labradoodle | Male | neutered | 3 years and 1 month old | 63 lbs

My labordoddle had his first injection for heart worms on Tuesday. He started throwing up last night. Is drinking water and has an appetite. Should we call the vet or is this just a side effect. Thanks

If there is no coughing or respiratory distress then I would not worry over a single instance if vomiting. If it continues or his appetite changes and coughing is noted then I would have him checked to see what is going on
