Why is my 5-week-old puppy vomiting and has diarrhea after new food?

Thank you for submitting your question regarding Pj. I'm sorry to hear that he is experiencing vomiting and diarrhea. If a dog is going to suffer a vaccine reaction, it typically occurs the same day as the vaccination. So this is likely unrelated. He may be experiencing GI upset secondary to all the new treats. I would stop those for now. Being so young and small, he should see his veterinarian if symptoms persist. In the meantime, encourage him to eat and drink small amounts. It will be easy for him to become dehydrated at his size. I hope this information helps!

Switching foods too quickly can cause digestive upset such as vomiting and diarrhea. It would be best to return to Oli's original food until his stomach settles and then start a gradual change to the new food over a period of 7-9 days, slowly adding in more of the new food over time. This can help minimize stomach upset from the new food as he adjusts.

We can have diarrhea due to stress (of a move to new home) or diet changes, however in young dogs we also worry about intestinal parasites (both worms and Protozoa that aren't killed by deworming) and in some cases depending on vaccine status parvovirus. For this reason it is best to have your pup checked at the vet and bring a stool sample for them to test. Until then you can pick up a probiotic for dogs at the vet or pet store and try feeding plain cooked white rice and boiled shredded chicken breast for a day or two.

Hormonal changes or diet changes (such as suddenly switching to the puppy food) can sometimes cause diarrhea post-birth, however if it is continuing, bringing in a fecal sample of Lacey's stool to your vet is a good next step. Your vet can check for common parasites or other issues that could be causing the diarrhea, especially if a bland meal hasn't helped. If the diarrhea continues and the fecal comes back negative, a more thorough exam from your vet is best.

Thank you for submitting your question regarding Giacomo. I'm sorry to hear you are having all of these problems with him. About 75% of the time ongoing diarrhea in puppies is related to intestinal parasites or diet. So have your veterinarian ensure he does not have any parasites including giardia. If he is negative and has been properly dewormed, I should start him on a prescription low fat diet that is highly digestible. I use Purina ProPlan Veterinary Diets EN as it is safe for use in growing puppies. If this diet does not resolve the diarrhea, he may require a diet for a food allergy such as a hydrolyzed formula. I hope this information helps!

Hi there! Sorry to hear that she is not feeling well. The clinical signs you describe are concerning when they occur in a puppy as they can be seen with serious gastrointestinal infections such as Parvovirus. Other possibilities include intestinal worms and dietary indiscretion, among other possibilities. The sooner these conditions are treated the better the outcome tends to be. For this reason, I recommend that you have her evaluated by your veterinarian to check for these possibilities and to start therapy based on findings. At the very least they can address dehydration if present and start her on anti-diarrhea medications. Good luck! Keeping my fingers crossed for your girl!

I suggest a vet check up for Mia. The diarrhea and vomitting may be due to dietary indiscretions, parasites or viral. Even though she has received preventative care, parasites or infection such as parvo or corona is still possible.
