Puppy vomited yellow after breakfast and is whining. What to do?
I am very sorry to hear that Nova is experiencing these problems, I am sure it is very unsettling for you both. There are a number of potential causes of such clinical signs, including dietary indiscretion, pancreatitis, parasite infestation, infection, and ingestion of a toxin or poison. I would believe the most likely cause is a dietary indiscretion, as puppies are known for getting into things they shouldn't.
Because you have only noticed one episode, I would continue to monitor Nova at home.
Rest Nova's gastrointestinal tract by holding back food for a few hours. Then you can continue with a bland and easily digested food of the boiled chicken breast and white rice diet and provide plenty of fresh water. I also find that boiled, mashed skinless sweet potato is helpful for diarrhoea if it were to begin.
If Nova does not improve, has profuse vomiting or diarrhoea, you notice fresh blood, Nova seems lethargic, in pain or depressed I would advise a trip to the veterinarian.
