Pet's info: Dog | Labradoodle | Female | spayed | 7 months and 4 days old | 33 lbs
In the past two days my dog has been vomiting. Sometimes it a yellow, foamy bile looking product. Other times it’s her kibble - unchewed and she then starts eating it. She has been on puppy food since we got her at 12 weeks (she is now 7 months old and near 40 pounds). Otherwise she is active and alert and playful. Bowls are fine as well with no blood or runny poop. She completed antibiotics for a UTI on Monday. Could this be a side effect of the meds?

Antibiotics and urinary tract infections themselves can both cause nausea/vomiting. However, as you finished the antibiotics 5 days ago, it is less likely that the vomiting is due to the UTI antibiotics. If she has recently gotten table food or had access to food from the garbage, she may have a condition called pancreatitis caused by a sudden high fat meal that may cause vomiting, diarrhea, abdominal pain. A trip to your veterinarian for screening bloodwork to rule out a liver/kidney/pancreas issue as the cause of the vomiting, subcutaneous fluid therapy, anti-nausea medication (cerenia), and a prescription intestinal diet is advised. If you are not able to get an appointment immediately, I recommend feeding only a bland diet of boiled rice and chicken (with no regular kibble) for the next 3-5 days. Sometimes this alone helps resolve the symptoms of mild gastroenteritis. Good luck!
