My puppy threw up once but is eating and active. Is he okay?

Updated on September 23rd, 2025

My 40 day gsd puppy vomits one time in today's morning. Now after 12 hours he don't vomit again. He is active and interested in eating. He seems ok. Is this a good sign. I was so tensed because of this because my previous puppy died because of chronic vomiting. Tell me in details the reasons of vomit. Thanks

It is difficult to tell you exactly the reason of the vomiting episode. What I can tell you is that in puppies the most common reasons for it are related to diet and to gastrointestinal infections/parasite infestations. Chronic vomiting is dangerous because it can lead to dehydration and severe secondary complications in puppies.
Make sure your new gsd is regularly vaccinated and dewormed.

    Good question. Vomiting in young puppies usually indicates either a transitory stomach or intestinal upset or possibly a viral infection, especially if your puppy has not had any puppy vaccinations. Due to the small size of this puppy, I feel you should seek out your local veterinarian or emergency veterinary service in order to have him examine and treated as soon as possible. Hopefully its just a simple intestinal upset from eating something besides his pet food. If not, your veterinarian will run diagnostic tests to rule out specific diseases and provide therapy to rehydrate and support him while he is recovering. Be sure to continue to gather information regarding Bo's vomiting, if it continues, before you have him examined. In addition, check around the house to be sure Bo hasn't chewed up and eaten any foreign materials. Glad you reached out to us for advice as I feel you should try to have Bo looked soon in order avoid complications such as dehydration, Thank you and all the best to you and Bo. Steve Popish, DVM.

    Vomiting could be caused by parasites, change in diet, toxin ingestion, infectious viral diseases, blockage in the intestines caused by ingestion of a foreign body, or a mass/growth in the gastrointestinal tract. There is also the possibility of parvovirus infection (a potentially fatal disease that causes gastrointestinal issues such as vomiting and diarrhea) which can be very severe in puppies. Please make an appointment to have Leo seen by a veterinarian as soon as possible for diagnosis and treatment, as a puppy who is vomiting and not eating can rapidly develop low blood sugar and dehydration that can be very dangerous and even fatal if left untreated.

My 6-week GSD puppy threw up white after vaccination. What's wrong?
I recommend to call your veterinarian. Puppies can vomit for many reasons but something like a vaccine reaction may be the cause and this needs to be treated. Your vet will make a recommendation based upon her exam yesterday. Just so you know, German Shepherds need to eat diets formulated for large breed puppies. This helps to ensure that they grow and develop properly. I recommend Royal Canin German Shepherd Puppy. It will ensure even, normal growth and is very easy to digest because the GSD can be prone to an upset stomach. I hope this helps and please feel free to post any additional questions.

My active dog vomits a little in the afternoon. Is that normal?
It can be normal for dogs to vomit occasionally. You should be concerned if your dog continues to vomit and can't stop. You should also watch for other symptoms like diarrhea. If your dog continues to decline, I would suggest a Vet asap. However, if this was a one time thing and your dog seems fine, it could just be that your dog had an upset tummy, or was too active and just vomited. It happens!

My 1-month German Shepherd puppy is vomiting. Should I see a vet?
It sounds as Jackey is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. i would recommend taking him to the vet the first chance you get, he will need to be checked first, if the vet thinks it's a simple gastrointestinal infection he will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better.

Why is my German Shepherd puppy throwing up undigested food?
Spirocerca Lupi is a parasite that can be found in dogs in Egypt, it causes a mass in the esophagus which causes chronic regurgitation, which might be what Misa is suffering from. it could also be a gastrointestinal infection, possibly parvo if she is not vaccinated. you need to take her to the vet ASAP in order to get that checked and treated.

My puppy threw up after playing and then ate it. What should I do?
It is not that unusual for a puppy to be sick, especially if he has been running around and eaten recently. As long as the pup seems in goid form I wouldnt worry too much. However if he seems dull or continues to vomit then a trip to the vet would be wise.

My German Shepherd puppy is weak after vomiting. What should I do?
Hello, You can try to syringe her water to keep her hydrated and rub syrup on her gums to prevent low blood sugar. However, Olie must see a veterinarian to determine the cause of vomiting and receive proper treatment. Typically, vomiting in a puppy her age is secondary to parasites, a virus, or even an intestinal obstruction.

Vet Q & A
My 9-week-old puppy won't eat and keeps throwing up. Is it serious?
This could be a number of things - parasites, a bacterial or viral GI infection, or even an intestinal blockage. At 2.5 months of age, Gus is especially at risk for parvovirus, a serious GI infection. We always worry about fluid loss in young puppies, so I would recommend getting him to a vet ASAP, to diagnose the cause of the vomiting, and start appropriate therapy.
