My new puppy won't eat, vomits, has diarrhea. Is he seriously ill?

Updated on September 23rd, 2025

Pet's info: Dog | German Shepherd | Male | unneutered | 1 month and 23 days old | 7 lbs

My new puppy won't eat anything and hasn't eaten in two days. He has vomitted and has diarrhea, and will only drink water. He's been laying down all day and only gets up to go to the bathroom. Should I be worried? or is this him getting used to his new life and being nervous still

Unfortunately, this is not normal behavior for a young puppy and is pretty concerning. At less than two months old, your puppy needs to eat regularly or he risks having low blood sugar, which can cause serious health problems. Vomiting is not typically caused by stress and all these signs make me worry about a more serious illness. Please have him seen by a veterinarian right away because his lack of appetite and vomiting are very serious.

A change in appetite and attitude can be from stress if a new addition but the vomiting should not be. Since it has been going on for a few days now I would have your vet check to see what is causing it and to make sure it isn't something your new puppy can catch.

Honestly it could be either. I can give you a home remedy to see if that helps. Feed Prada a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If she refuses to eat the bland diet, she vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away

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.

My 15-day-old puppy is vomiting, not eating, and has bloody diarrhea.

Whisky sounds very ill, and at his age, I would be concerned his symptoms are due to parvovirus. That would cause vomiting, diarrhea, and blood in the diarrhea (the red color of his poop). Very young puppies are extremely fragile, and his symptoms are quite serious. I would consider this a medical emergency and he needs to see a vet now. Please take him into one immediately.

My dog is vomiting, diarrhea, weak, and won't eat. Is it serious?

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. it does sound serious. Profound vomiting and diarrhea in such a young puppy can lead quickly to dehydration. If possible, please take Bailey to your local emergency service for an appointment tonight. If this is not an option, you should withhold any water or food overnight, offer him very small amount of water in the morning and take him to your regular vets as soon as they open on Saturday morning.

Why is my puppy vomiting and has diarrhea after eating 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!

My puppy has diarrhea, won't eat, and seems sick. When to see vet?

If Bruno has had diarrhea and decrease appetite for 3 days I would recommend a visit to the vet. A young pup may have parasites, viral disease or a foreign body that can cause diarrhea. But at his age he can become debilitated quickly when sick so a vet visit at this point is probably a good idea. I hope he recovers quickly.

Why is my 8-week-old puppy vomiting, having diarrhea, and not eating?

Baily is so cute! I am concerned though that he is not eating and having such intestinal upset. I would recommend you take Baily in for an exam with your vet as soon as possible. Puppies this young can get dehydrated very quickly and become quite ill. I am worried about the possibility of intestinal parasites, eating something he shouldn't have (dietary indiscretion), or even a bacterial or viral infection (like parvovirus). Baily may need some tests to see what the underlying cause is, such as a parvo test and fecal test. He also may need some anti-nausea medication, antibiotics, or even fluid therapy if he is dehydrated. I hope he gets back on track quickly!

My puppy is throwing up, not eating, and lethargic. Is it serious?

Julia should be examined by your veterinarian today. Vomiting and a lack of appetite in a puppy can quickly lead to dehydration which can kill. If she is not vaccinated, diseases such as distemper should be ruled out. At the very least, she may need supportive care (IV or subcutaneous fluids, anti emetics and parenteral nutrtion) until she is eating on her own and not vomting any longer.
