Is It Normal for a Female Dog in Heat to Stop Eating and Vomit Yellow Liquid?

When a female dog is in heat, it's common for her to experience various changes in her behavior and physical condition. These can include decreased appetite and gastrointestinal issues such as vomiting.

Why She May Not Be Eating

  • Hormonal Changes: Estrogen and progesterone levels fluctuate during heat, which can affect appetite.
  • Vaginal Discharge: The discharge from the vagina can be foul-smelling and unappetizing to dogs.
  • Pain and Discomfort: Heat can cause uterine contractions and discomfort, which can lead to decreased appetite.

Why She May Be Vomiting Yellow Liquid

  • Bile Acid Reflux: When a dog doesn't eat, its stomach acids can accumulate and cause reflux, leading to vomiting of yellow liquid.
  • Gastritis: The hormonal changes and increased vaginal discharge can irritate the stomach lining, causing inflammation and vomiting.
  • Liver Issues: In rare cases, severe vomiting during heat can indicate liver problems.

Is This Normal?

Mild decreased appetite and occasional vomiting of yellow liquid during heat are generally considered normal. However, if your dog is vomiting excessively, refuses to eat for more than 24 hours, or has other concerning symptoms such as lethargy, fever, or diarrhea, it's important to seek veterinary attention promptly.
