Abby needs to be examined by the veterinarian today. She is too young to be protected from diseases and certain viruses, including Parvo, can present like this. Other possible causes of vomiting include parasites, eating something she shouldn’t have or getting in to medications...etc. Abby is too young to have the reserves of adult dogs and so she needs intervention earlier. Bring in a sample of stool for testing for Parvo and parasites. Best of luck.

    Hi there and thank you for using pet coach to address your concern. With these symptoms and her age, I would recommend having a veterinarian examine her. I would consider having her tested for parvo virus and have abdominal x-rays taken as this may also be a GI foreign body obstruction. I hope this helps! If you are unable to get to the veterinarian right away, I would initiate a bland diet as directed below. If the vomiting persists for more than 24 hours on the bland diet I would strongly suggest getting her seen by a veterinarian sooner rather than later. Please let me know if you have any other questions or concerns. I am also available via consultation if needed.

    Dogs don't get morning sickness like humans do, so her recent vomiting is not likely to be from pregnancy. Common causes of vomiting in dogs includes dietary intolerance, dietary indiscretion, food allergy, intestinal parasites, GI blockage, gastroenteritis, bacterial or viral infection, IBD, pancreatitis, among others. I would recommend that you have Nancy checked out by a vet to see if there is a cause of he nausea and poor appetite. The vet may recommend diagnostics such as bloodwork or x-rays.

    It sounds as if Abby is very ill. Vomiting and loss of appetite can be caused by a number of issues including illness such as parvo, obstructions, and other problems. Since she is so ill it is best to seek veterinary care ASAP to figure out what is causing her vomiting and get her care.
