My dog is in heat, not eating, and vomiting water. Is this normal?

These are not normal symptoms associated with being in heat, so I would be concerned about some other illness. If she hasn't eaten in several days and is still vomiting, I would recommend taking her to the emergency vet. She is likely very dehydrated at this point, and we need to figure out what is causing the nausea.

Dogs can feel lethargic and not want to eat during their heat cycle especially their first one. However, this shouldn't last long. Vomiting is a bit unusual for a heat cycle. She should get a physical examination by a veterinarian to make sure she doesn't have gastroenteritis or pancreatitis.

Vomiting is not usually a symptom of being in heat. It sounds as if she might have eaten something that either disagreed with her or something that has gotten stuck somewhere in her gastrointestinal tract. She could have been exposed to some sort of toxin or irritant in her environment or this could be early signs of another condition or disease process. She could also have a uterine infection causing these symptoms. I recommend getting her seen by your veterinarian as soon as possible. Your vet will do an exam, blood work and possibly x-rays to determine the cause of the illness and suggest an effective treatment plan. Additionally, unless she is a purebred that will improve the breed by producing offspring, I highly recommend getting her spayed once she is over her illness. This will eliminate the chance of her getting a life-threatening uterine infection and greatly reduce her chances of developing breast cancer in the future.

Vomiting is not normal for a dog that has recently been in heat. It may indicate an infection in her uterus which can be life threatening. Or she may have a primary GI cause for the vomiting. If she continues to vomit or otherwise act sick I recommend a vet visit

Thank you for submitting your question regarding your dog. No, this is not normal. I recommend having her seen by her veterinarian today. It is best to determine why she is vomiting and refusing food. From there, proper treatment can be started. I worry that she will become dehydrated if she is not already. In this case, she will needs fluids to help her feel better. Good luck!

This episode may be dietary related and completely incidental. As a first line approach, I would suggest to withhold food for the next 8-12 hours and then start feeding with a bland diet based on boiled chicken and rice in small portion every 6 hours for the following 48hours. Then gradually reintroduce the normal diet over 5 days. I would definitively recommend a veterinary check up if the signs persist or you notice diarrhoea, more vomiting, lethargy or inappetence. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

I am so sorry to hear that Coco is not well! I would also be concerned if she is vomiting and not feeling well. It is possible it is related to her intact status- uterine infections, for example, can cause you to be very ill. It is also possible that it is unrelated- viruses, dietary indiscretion and foreign bodies are also examples of common causes of vomiting. It would be safest to take her in and have an exam done and possibly other tests to see if there is an underlying cause that can be remedied. I hope it is nothing too serious!
